Calling void methods but deference parameters

I call two methods void at the same time, the problem is that the second method I call is not executed, only the first call works fine. The only difference is the parameters
Which calls the method :
private void calculateDistributorRabat(InvoiceHeader invoice, Distributor distributor) {
insertRabatToWallet(distributor.getUser(), invoice.getPurchaseOrder());
insertRabatToWallet(distributor.getBranchOffice().getUser(), invoice.getPurchaseOrder());
}
This is the void method that is being called :
private void insertRabatToWallet(User user, PurchaseOrder purchaseOrder) {
Map<ProductType, Rabat> rabatMap = rabatService.getRabatMapPayPo(user.getUserType());
Wallet wallet = walletDao.findByUser(user);
if (wallet == null) {
wallet = new Wallet();
wallet.setUser(user);
}
for (PurchaseOrderDetail pd : purchaseOrder.getPurchaseOrderDetails()) {
Rabat rabat = rabatMap.get(pd.getProductType());
if (rabat == null) {
continue;
}
BigDecimal rabatAmount = rabat.getNominal().multiply(new BigDecimal(pd.getProductQty()));
wallet.setTotalDebet(wallet.getTotalDebet().add(rabatAmount));
wallet.setCurrentAmount(wallet.getCurrentAmount().add(rabatAmount));
WalletTransaction wt = new WalletTransaction();
wt.setAmount(rabatAmount);
wt.setDescription("Rabat " + user.getUserType() + " [" + purchaseOrder.getPurchaseOrderNumber()
+ "] (" + pd.getProductType().getCode()
+ "): Rp." + rabat.getNominal().setScale(0).toString()
+ " x " + pd.getProductQty());
wallet.addWalletTransaction(wt);
walletDao.save(wallet);
}
}

How to fix "double printing when I clicked twice on the pretty dialog button"

I debugging my application then I tried clicking twice and fast on the pretty dialog button and it print twice I expect that even I clicked twice it will not print twice.
I tried error handler codes but it was not working.
prettyDialog.addButton("YES",

}
});
prettyDialog.dismiss();
}
})
.show();
I expect that it will not print twice even I clicked the "YES" pretty dialog button.

i think you can just do a trick like this
create a count variable count=0;. In button click, validate condition such that if(count==0) show dialog and make count = 1. (with this dialog will not open second time) while dismissing dialog make count = 0 again.
I think this will work
Hope it helps.
if(count == 0){
count = 1 ;
//showdialog process
}
and right before dismiss()
......
count = 0;
prettyDialog.dismiss();

Android moving GraphView and play MediaPlayer at the same time

I'm working on a project, where I need to show the pitches of the words (from the song) in a GraphView. I wrote a program that would get the pitches from a song and create a .txt file from it.
Then I wrote a class, that reads the file and creates a list from it. So in the end I would have a list that consists of words and word contains pitches. In the MakePitchesList you can see what the pitches output from a song looks like. I have 0,14:23281,61 on every line. The first part of the line is timeOccurance meaning, when this pitch was heard and the second part is the pitch itself. So in this example the timeOccurance would be 0,14 and pitch at that given time 23281,61.
Here are the three classes that make a wordsList out of a pitch .txt file.
public class Pitch{
float occuranceTime;
float pitch;
public void setOccuranceTime(float occuranceTime) {
this.occuranceTime = occuranceTime;
}
public float getOccuranceTime() {
return occuranceTime;
}
public void setPitch(float pitch) {
this.pitch = pitch;
}
public float getPitch() {
return pitch;
}
}
public class MakePitchesList {
String[] pitches;
List<Pitch> listOfPitches = new ArrayList<Pitch>();
public List<Pitch> getListOfPitches(){
getPitches();
for (String pitchString: pitches) {
Pitch pitch = new Pitch();
makeListOfPitches(pitch, pitchString);
}
return listOfPitches;
}
public void makeListOfPitches(Pitch pitch, String pitchString){
pitch.setPitch(getPitchesInfo(pitchString, 1));
pitch.setOccuranceTime(getPitchesInfo(pitchString, 0));
listOfPitches.add(pitch);
}
public String[] getPitches() {
pitches = pitchesRaw.split("\\r?\\n");
return pitches;
}
private float getPitchesInfo(String pitch, int position){
String[] frequencyAndTime = pitch.split("\\:");
if(position == 0){
return Float.parseFloat(frequencyAndTime[0].replace(',', '.'));
}
if(position == 1){
return Float.parseFloat(frequencyAndTime[1].replace(',', '.'));
}
else return 0;
}

}
List<Pitch> oneWord = new ArrayList<>();
List<List<Pitch>> wordList = new ArrayList<>();
public List<List<Pitch>> makeWordsList(List<Pitch> pitchList){
pitches = pitchList;
int pauseCounter = 0;
for (int i = 0; i < pitchList.size(); i++) {
if(pitchList.get(i).getPitch() > 10000){
pauseCounter++;
} else {
if(pauseCounter > 0){
if(pauseCounter >= 5){
wordList.add(oneWord);
oneWord = new ArrayList<>();
}
pauseCounter = 0;
}
oneWord.add(pitchList.get(i));
}
}
if(oneWord.size() > 0){
wordList.add(oneWord);
}
return wordList;
}
}
Now from that wordsList I create a scrollable GraphView that on paper would look something like this.
Now I have set the boundaries for the GraphView: MinX = -0.8; MaxX = 0.4. This way I'm showing 1 sec at a time on screen. Then I start a thread so it would change the coordinates of the GraphView by 0.1 every 100ms, which should add up as 1 every sec.

private LineGraphSeries<DataPoint> series;

To sum up what the code does: it gets the wordsList from the pitches, initializes the graph, starts listening button click. When button is clicked, it starts moving graph as described above and plays audio.
The problem is that the audio and moving graphView go out of sync. For the first 10sec or so it works like it should but then the lines start falling behind. I would really appreciate if someone took their time to understand all of this mess.
Maybe picture of the actual final graphView will also help. . Blue line is the first incoming word.

return array from inside an if,for statement

I am building a tag reader for inventory purpose. Using the for loop to iterate through the tags to count/total the ids. I get an error on my return line "tagsFound cannot be resolved into a variable". How do i use the variable inside the for loop and then access it outside the loop?
public String[] getTags(AlienClass1Reader reader)throws AlienReaderException{
int coneCount = 0;
int drumCount = 0;
// Open a connection to the reader
reader.open();
// Ask the reader to read tags and print them
Tag tagList[] = reader.getTagList();
if (tagList == null) {
System.out.println("No Tags Found");
} else {
System.out.println("Tag(s) found: " + tagList.length);
for (int i=0; i<tagList.length; i++) {
Tag tag = tagList[i];
System.out.println("ID:" + tag.getTagID() +
", Discovered:" + tag.getDiscoverTime() +
", Last Seen:" + tag.getRenewTime() +
", Antenna:" + tag.getAntenna() +
", Reads:" + tag.getRenewCount()
);
//tagFound[i]= "" + tag.getTagID();
String phrase = tag.getTagID();
tagFound[i] = phrase;
String delims = "[ ]+";
String[] tokens = phrase.split(delims);
if (tokens[0].equals("0CCE") && tokens[3].equals("1001")){drumCount++;}
if (tokens[0].equals("0CCE") && tokens[3].equals("1004")){coneCount++;}
String[] tagsFound;
tagsFound[i] = tag.getTagID();
}
System.out.println("Cones= " + coneCount);
System.out.println("Drums= " + drumCount);
// Close the connection
reader.close();
return tagsFound;
}
}

public String[] getTags(AlienClass1Reader reader)throws AlienReaderException{
int coneCount = 0;
int drumCount = 0;
// Open a connection to the reader
reader.open();
// Ask the reader to read tags and print them
Tag tagList[] = reader.getTagList();
if (tagList == null) {
System.out.println("No Tags Found");
} else {
System.out.println("Tag(s) found: " + tagList.length);
String[] tagsFound = new String[tagList.length];
for (int i=0; i<tagList.length; i++) {
tagsFound = "";
Tag tag = tagList[i];
System.out.println("ID:" + tag.getTagID() +
", Discovered:" + tag.getDiscoverTime() +
", Last Seen:" + tag.getRenewTime() +
", Antenna:" + tag.getAntenna() +
", Reads:" + tag.getRenewCount()
);
//tagFound[i]= "" + tag.getTagID();
String phrase = tag.getTagID();
tagFound[i] = phrase;
String delims = "[ ]+";
String[] tokens = phrase.split(delims);
if (tokens[0].equals("0CCE") && tokens[3].equals("1001")){drumCount++;}
if (tokens[0].equals("0CCE") && tokens[3].equals("1004")){coneCount++;}
tagsFound[i] = tag.getTagID();
}
System.out.println("Cones= " + coneCount);
System.out.println("Drums= " + drumCount);
// Close the connection
reader.close();
return tagsFound;
}
}
the returned array will have empty strings in the positions where the tag does not satisfy the criteria.

Inputting data to a HashMap

I am making a Minecraft Server Plugin using the Bukkit Api.
Basically when my server stops, I use the onDisable() to store two hashmap contents to a config, then when the server starts, I use the onEnable() to take that info from the config and put it back in the HashMaps. That doesn't work.
Here are my methods: the saveBans is in the onDisable() and the loadBans is in the onEnable():
public class utilReloadSave {
static settingsmanager settings = settingsmanager.getInstance();
public static void saveBans() {
ArrayList<String> bans = new ArrayList<String>();
for (UUID play : Cooldown.cooldownPlayers.keySet()) {
settings.getConfig().set("bans." + play, Cooldown.getTime(play, "TempBan"));
bans.add(play.toString());
}
settings.getConfig().set("banlist", bans);
settings.saveConfig();
}
public static void loadBans() {
FileConfiguration config = settings.getConfig();
ArrayList<String> bans = (ArrayList<String>) config.getStringList("banlist");
for (String uuid : bans) {
Cooldown.cooldownPlayers.put(UUID.fromString(uuid), new utilCooldown(UUID.fromString(uuid), config.getInt("bans." + uuid), System.currentTimeMillis()));
}
config.set("bans", null);
config.set("banlist", null);
settings.saveConfig();
}
}
That seems to work. The problem is I use a onPlayerJoin Event:
#EventHandler
public void onLogin(PlayerLoginEvent e) {
Player play = e.getPlayer();
if (play.isBanned()) {
if (Cooldown.isCooling(play.getUniqueId(), "TempBan")) {
File player = new File(basic.plugin.getDataFolder() + "/players/" + play.getUniqueId() + ".yml");
FileConfiguration config = YamlConfiguration.loadConfiguration(player);
List<String> list = config.getStringList("banned.temp.reason");
String reason = list.get(list.size()-1);
if (Cooldown.getTime(play.getUniqueId(), "TempBan") < 60000L) {
e.disallow(PlayerLoginEvent.Result.KICK_BANNED, ChatColor.YELLOW + "" + ChatColor.BOLD + "You are still banned for " + Cooldown.getRemaining(play.getUniqueId(), "TempBan") + " seconds." + ChatColor.RED + " Reason: " + reason);
return;}
if (Cooldown.getTime(play.getUniqueId(), "TempBan") < 3600000L) {
e.disallow(PlayerLoginEvent.Result.KICK_BANNED, ChatColor.YELLOW + "" + ChatColor.BOLD + "You are still banned for " + Cooldown.getRemaining(play.getUniqueId(), "TempBan") + " minutes." + ChatColor.RED + " Reason: " + reason);
return;}
if (Cooldown.getTime(play.getUniqueId(), "TempBan") < 86400000L) {
e.disallow(PlayerLoginEvent.Result.KICK_BANNED, ChatColor.YELLOW + "" + ChatColor.BOLD + "You are still banned for " + Cooldown.getRemaining(play.getUniqueId(), "TempBan") + " hours." + ChatColor.RED + " Reason: " + reason);
return;}
e.disallow(PlayerLoginEvent.Result.KICK_BANNED, ChatColor.YELLOW + "" + ChatColor.BOLD + "You are still banned for " + Cooldown.getRemaining(play.getUniqueId(), "TempBan") + " days." + ChatColor.RED + " Reason: " + reason);
return;
} else {
File player = new File(basic.plugin.getDataFolder() + "/players/" + play.getUniqueId() + ".yml");
FileConfiguration config = YamlConfiguration.loadConfiguration(player);
List<String> list = config.getStringList("banned.perm.reason");
String reason = list.get(list.size()-1);
e.disallow(PlayerLoginEvent.Result.KICK_BANNED, ChatColor.YELLOW + "" + ChatColor.BOLD + "You are permanentely banned! " + ChatColor.RED + "" + ChatColor.BOLD + "Reason: " + reason);
return;
}
}
}
which will check if there is something in the Hashmap but there isn't since it returns the else statement.
public static HashMap<UUID, utilCooldown> cooldownPlayers = new HashMap<UUID, utilCooldown>();
public static void add(UUID player, String ability, long seconds, long systime) {
if(!cooldownPlayers.containsKey(player)) cooldownPlayers.put(player, new utilCooldown(player));
if(isCooling(player, ability)) return;
cooldownPlayers.get(player);
utilCooldown.cooldownMap.put(ability, new utilCooldown(player, seconds * 1000, System.currentTimeMillis()));
}
public static boolean isCooling(UUID player, String ability) {
if(!cooldownPlayers.containsKey(player)) return false;
if(!utilCooldown.cooldownMap.containsKey(ability)) return false;
return true;
}
public static double getRemaining(UUID player, String ability) {
if(!cooldownPlayers.containsKey(player)) return 0.0;
if(!utilCooldown.cooldownMap.containsKey(ability)) return 0.0;
return utilTime.convert((utilCooldown.cooldownMap.get(ability).seconds + utilCooldown.cooldownMap.get(ability).systime) - System.currentTimeMillis(), TimeUnit.BEST, 1);
}
public static void removeCooldown(UUID key, String ability) {
if(!cooldownPlayers.containsKey(key)) {
return;
}
if(!utilCooldown.cooldownMap.containsKey(ability)) {
return;
}
utilCooldown.cooldownMap.remove(ability);
}
#SuppressWarnings("deprecation")
public static void handleCooldowns() {
if(cooldownPlayers.isEmpty()) {
return;
}
for(Iterator<UUID> it = cooldownPlayers.keySet().iterator(); it.hasNext();) {
UUID key = it.next();
cooldownPlayers.get(key);
for(Iterator<String> iter = utilCooldown.cooldownMap.keySet().iterator(); iter.hasNext();) {
String name = iter.next();
if(getRemaining(key, name) <= 0.0) {
OfflinePlayer p = Bukkit.getOfflinePlayer(key);
p.setBanned(false);
removeCooldown(key, name);
}
}
}
}
public static long getTime(UUID player, String ability) {
return (utilCooldown.cooldownMap.get(ability).seconds + utilCooldown.cooldownMap.get(ability).systime) - System.currentTimeMillis();
}

I assume:
You have tested that the ArrayList in loadBans is not empty - before blaming the HashMap.
You have also checked whether or not these methods loadBans and saveBans are being called.
You have manually opened the config files to see what's in there.
You can use Debug-mode or extensively use System.out.println(...) for debugging. Whenever something is null or empty, while it shouldn't be - try to go back and see where it wasn't null or empty.
