How to get a specific value from a string name via config - java

The green is the lore
and the yellow is the displayname
http://puu.sh/k2iI7/62619f9536.jpg
I'm trying to seperate them in there rightful places for some odd reason there both appearing in both of the places.
items.java
public ItemStack applyLore(ItemStack stack, String name, String lore1){
ItemMeta meta = stack.getItemMeta();
meta.setDisplayName(name.replaceAll("&([0-9a-f])", "\u00A7$1"));
ArrayList<String> lore = new ArrayList<String>();
lore.add(lore1.replaceAll("&([0-9a-f])", "\u00A7$1"));
meta.setLore(lore);
stack.setItemMeta(meta);
return stack;
}
// p.getInventory().addItem(new ItemStack(Integer.parseInt(s), 1));
public void giveItemfromConfig(Player p)
{
String name ="name:";
String lore ="lore:";
for ( String s : plugin.file.getFile().getStringList(plugin.file.path) ) {
try {
s.split(" ");
if ( s.contains(name) || s.contains(lore) )
{
String namelength = s.substring(name.length());
String lorelength = s.substring(lore.length());
p.getInventory().addItem(applyLore(new ItemStack(Integer.parseInt(s.split(" ")[0])),
namelength.replace("_", " ").replace("ame:", "").replace("e:", "").replace("lor", "").replace("ore", ""),
lorelength.replace("_", " ").replace("lor:", "").replace("e:", "").replace("am", "").replace("lor", "").replace("ore", "")));
p.sendMessage("debug");
} else {
///nope.exe
p.getInventory().addItem(new ItemStack(Integer.parseInt(s)));
}
} catch(Exception e)
{
e.printStackTrace();
Bukkit.getConsoleSender().sendMessage(ChatColor.AQUA + "Error in Config, Your id must be a integer ERROR:" + e);
}
}
}
config.yml
ChestPopulater:
items:
- 276 name:cookie

First thing is the problem is because of "Integer.parseInt(s)".
I dont know why you added this one as we dont have full source code or idea what you are trying to do with String "s" so that you will get result.
If you are doing it to get "276" , I will suggest you to do following :
String s2 = s.replaceAll("[A-Za-z]","").replace(":","").trim();
Integer i = Integer.parseInt(s2);

Checking if item lore contains contains string (loren.contains("§eSigned from "))

I only want to check for:
if (lore.contains("§eSigned of ")) {
but it doesn't get that it does contain "§eSigned of "
I wrote a Minecraft Command /sign you can add a lore to an item ("Signed of playerrank | playername").
Then i wanted to add an /unsign command to remove this lore.
ItemStack is = p.getItemInHand();
ItemMeta im = is.getItemMeta();
List<String> lore = im.hasLore() ? im.getLore() : new ArrayList<String>();
if (lore.contains("§eSigned of " + getChatName(p))) { // this line is important!
for (int i = 0; i < 3; i++) {
int size = lore.size();
lore.remove(size - 1);
}
im.setLore(lore);
is.setItemMeta(im);
p.setItemInHand(is);
sendMessage(p, "§aThis item is no longer signed");
} else {
sendMessage(p, "§aThis item is not signed!");
}
return CommandResult.None;
Everything works fine until you e.g. change your name. than you can't remove the sign because getChatName(p) has changed.
To fix this i only want to check
if (lore.contains("§eSigned of ")) {
but than it doesn't get it and returns false. (it says lore does not contain "§eSigned of ")
I tried a lot but it only works with the string "§eSigned of " and getChatName(p).
As the documentation "contains" searches for the specific string so it should work as I thought right?
Add:
getChatName(p) returns the rank of the player and the playername like: "Member | domi"
sendMessage(p, "") sends a simple message in the Minecraft chat
The problem you run into is that contains(String) looks for a matching string. What you search for is a check if any string in the list starts with "§eSigned of ".
I would suggest adding a function isSignedItem like this:
private boolean isSignedItem(List<String> lore) {
for (String st : lore)
if (st.startsWith("§eSigned of "))
return true;
return false;
}
and then to use this function to check if the item is signed or not:
[...]
List<String> lore = im.hasLore() ? im.getLore() : new ArrayList<String>();
if (isSignedItem(lore)) { // this line is important!
for (int i = 0; i < 3; i++) {
int size = lore.size();
lore.remove(size - 1);
}

Get ID of the room from Json

I need to get the ID of room by its name from JSONObject.
I uploaded Json file here: https://gitlab.com/JaroslavVond/json/blob/master/Json
So I know the name of the room (Kitchen1) and I need to write some function in Java that will return me the ID of the room (in this case "1").
Any ideas how to do that?
So far I have something like this:
private static String GetIdRoom(String room) {
String id = "";
JSONObject myResponse = SendHTTP("/groups", "GET", "");
try {
// some code to get ID of room
} catch (Exception ex) {
System.out.println("error - " + ex);
}
return null ;
}
Iterator<?> ids = myResponse.keys();
while( ids.hasNext() ) {
id = (String) ids.next();
if(myResponse.getJSONObject(id).getString("name").equals(room)){
return id;
}
}

Java: Using .txt files to assign specific indexes of each line to an arraylist

My .txt file is
code1,description1,price1
code2,description2,price2
etc.
Using:
ArrayList<String> items = new ArrayList<String>();
String description;
File fn = new File("file.txt");
String[] astring = new String[4];
try{
Scanner readFile = new Scanner(fn);
Scanner as = new Scanner(System.in);
while (readFile.hasNext()){
astring = readFile.nextLine().split(",");
String code = astring[0];
items.add(code);
description = astring[1];
}
}catch(FileNotFoundException){
//
}
for(String things: items){
System.out.println("The code is: " + things + "The description is " + description);
}
My output prints out
code1 description1
code2 description1
code3 description1
I'm trying to figure out how to make the description update as the code's do. e.g.
code1 description1
code2 description2
code3 description3
If this question has been asked already, I apologize. I couldn't find out how to do it by searching around but if there's a reference to figure this out I'll close this down and go there. Thanks in advance!
The problem is with your logic. You are storing only astring[0] to the items ArrayList and overwriting the value of description each time. As a result on last value read is stored in description which you are printing in the loop.
I prefer creating a custom class as follows. (Just for the sake of demo otherwise you would declare your fields as private and provide getters and setters)
class MyObject {
public String code;
public String description;
public String price;
}
now instead of creating ArrayList of Strings you will create ArrayList of MyObject as follows
ArrayList<MyObject> items = new ArrayList<MyObject>();
now create a new instance of MyObject each time you read a line , populate its fields with the values from astring as follows
ArrayList<MyObject> items = new ArrayList<MyObject>();
File fn = new File("test.txt");
String[] astring = new String[4];
try {
Scanner readFile = new Scanner(fn);
Scanner as = new Scanner(System.in);
MyObject myObject;
while (readFile.hasNext()) {
astring = readFile.nextLine().split(",");
myObject = new MyObject();
myObject.code = astring[0];
myObject.description = astring[1];
myObject.price = astring[2];
items.add(myObject);
}
} catch (Exception e) {
System.out.println(e.getMessage());
}
and then finally print it using the same foreach loop as follows
for (MyObject item : items) {
System.out.println("The code is: " + item.code + " The description is: " + item.description + " The price is: " + item.price);
}
Output
The code is: code1 The description is: description1 The price is: price1
The code is: code2 The description is: description2 The price is: price2
The reason you're seeing that output is that you are not saving description along with the code inside the list, that is why the last description is saved within the description variable not all description values.
To solve this problem, you can create a simple Java Bean/POJO class
and wrap your data inside it and then you can simply fetch the value
you have saved it and then show it properly. Take a look at the code
below:
public class Launcher{
public static void main(String[] args) {
ArrayList<Item> items = new ArrayList<Item>();
File fn = new File("file.txt");
try {
Scanner readFile = new Scanner(fn);
while (readFile.hasNext()) {
String[] astring = readFile.nextLine().split(",");
String code = astring[0];
String description = astring[1];
String price = astring[2];
Item item = new Item(code, description, price);
items.add(item);
}
} catch (FileNotFoundException d) { // }
}
for (Item thing : items) {
System.out.println(String.format("The code is: %s\tThe description is: %s\tThe Price is %s",thing.getCode(),thing.getDescription(), thing.getPrice()));
}
}
}
class Item {
private String code;
private String description;
private String price;
public Item(String code, String description, String price) {
this.code = code;
this.description = description;
this.price = price;
}
public String getCode() {
return code;
}
public String getDescription() {
return description;
}
public String getPrice() {
return price;
}
}

Multiply contacts' name On update (ContentProviderOperation)

A very strange porblem. I'm tring to update contacts name by this rule:
- if a contact's name start with "bit" + space ("bit ") so -> update the contact's name to name.substring(4, name.length()), and that means that the contact name will update without the "bit ".
when I use name.substring from number that lower them 4 (I think until the space in contact's name) its working perfectly. When I use from the 4 character onwards the contact's name multiply. For exmaple, when i use name = name.substring(4, name.length()) while name equal to "bit Lili" its update to:
Lili Lili.
private void updateContact(String name) {
ContentResolver cr = getContentResolver();
String where = ContactsContract.Data.DISPLAY_NAME + " = ?";
String[] params = new String[] {name};
Cursor phoneCur = managedQuery(ContactsContract.Data.CONTENT_URI,null,where,params,null);
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
if ((null == phoneCur)) {//createContact(name, phone);
Toast.makeText(this, "no contact with this name", Toast.LENGTH_SHORT).show();
return;} else {ops.add(ContentProviderOperation.newUpdate(android.provider.ContactsContract.Data.CONTENT_URI)
.withSelection(where, params)
.withValue(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME, name.substring(4,name.length()))
.build());
}
phoneCur.close();
try {cr.applyBatch(ContactsContract.AUTHORITY, ops);}
catch (RemoteException e) {e.printStackTrace();}
catch (OperationApplicationException e) {e.printStackTrace();}}
Thanks!
Not a certain answer but it suppose to work the issue you have is with the
.withValue(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME //This specific part has a problem with the new update function
,name.substring(4,name.length()))
So my fix proposal is to change it to family name and given name change these as you need based on your question you want to remove the given name so it's a fix for that
public static boolean updateContactName(#NonNull Context context, #NonNull String name) {
if (name.length() < 4) return true;
String givenNameKey = ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME;
String familyNameKey = ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME;
String changedName = name.substring(4, name.length());
ArrayList<ContentProviderOperation> ops = new ArrayList<>();
String where = ContactsContract.Data.DISPLAY_NAME + " = ?";
String[] params = new String[]{name};
ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
.withSelection(where, params)
.withValue(givenNameKey, changedName)
.withValue(familyNameKey, "")
.build());
try {
context.getContentResolver()
.applyBatch(ContactsContract.AUTHORITY, ops);
} catch (Exception e) {
e.printStackTrace();
return false;
}
return true;
}

Needing to set spaces in a NULL stringbuilder value

I have a field that I am trying to set the length of 25 to by using StringBuilder and then populate it with string values in specific positions within that field. However, when I get a print out of the values in that field the value looks like this:
M0
Obviously I am needing to remove the "&#0" values from that field. Any help/direction would be appreciated.
Here is my code:
String b44 = toRequestIsoMessage.getString(B44_ADD_RESPONSE_DATA.bitId);
if (b44 == null) {
// ***** 20130604 MS - Told Ralph since that position 1 is space filled initially in the request to the CORE so that he can modify for the AVS. *****
String avsValue = " ";
try {
StringBuilder revB44Value = new StringBuilder();
revB44Value.setLength(25);
revB44Value.insert(0, avsValue);
if (decision.cidResponse.responseCode != null) {
revB44Value.insert(1, decision.cidResponse.responseCode);
} else {
revB44Value.insert(1, " ");
}
if (decision.cvvResponse.responseCode != null) {
revB44Value.insert(13, decision.cvvResponse.responseCode);
} else {
revB44Value.insert(13, " ");
}
String revB44 = revB44Value.toString();
toRequestIsoMessage.setString(B44_ADD_RESPONSE_DATA.bitId, revB44Value.toString());
} catch (InternalISOMsgException e) {
LOGGER.info(FormatData.fullStackTrace(e));
}
}
