Insert Button Not working after verifying duplicate entry

Hi I am beginner I am trying to create a reservation system somehow I can check now if there is duplicate entry however if there's no duplicate entry it is not inserting the data into the database but it if I remove my function to check the duplicate it can insert the data in database. Any suggestion? I am trying to figure it out but it still not working.No error but not adding.
private void btnreserveActionPerformed(java.awt.event.ActionEvent evt) {
try {
DB_Operation DB =new DB_Operation();
String cx1,contactnum11,email1,t11,venuee;
String amount1=aval.getText();
String bal1=b1.getText();
cx1=cx.getText();
contactnum11=contactnum1.getText();
email1=email.getText();
t11=t1.getSelectedItem().toString();
venuee=v.getSelectedItem().toString();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String Dateee = sdf.format(dad.getSelectedDate().getTime());
boolean unique;
unique = true;
String c1="8am to 12 pm";
String c3="8am to 5pm";
String c2="1pm to 5 pm";
ResultSet rsa= DB.searchQuery("SELECT * FROM `reserve1` WHERE `Date`='"+Dateee+"'");
if ( cx.getText().trim().length() == 0|| contactnum1.getText().trim().length() == 0||email.getText().trim().length() == 0){
final JPanel panel = new JPanel();
JOptionPane.showMessageDialog(panel, "All fields must be completed", "Error", JOptionPane.ERROR_MESSAGE);
}
else if(rsa.isBeforeFirst()){
while(rsa.next()){
if(rsa.getString("Venue").equalsIgnoreCase(venuee)&&
rsa.getString("Date").equalsIgnoreCase(Dateee)&& rsa.getString("Time").equals(t11)){
JOptionPane.showMessageDialog(null,"Duplicate Resevation!");
unique = false;
}
else if((t11.equals(c3))&&(rsa.getString("Venue").equalsIgnoreCase(venuee)&&
rsa.getString("Date").equalsIgnoreCase(Dateee)&& rsa.getString("Time").equals(c1))){
JOptionPane.showMessageDialog(null,"Half Day Resevation Exist!");
unique = false;
}
else if((t11.equals(c3))&&(rsa.getString("Venue").equalsIgnoreCase(venuee)&&
rsa.getString("Date").equalsIgnoreCase(Dateee)&& rsa.getString("Time").equals(c2))){
JOptionPane.showMessageDialog(null,"Half Day Resevation Exist!");
unique = false;
}
else if(unique=true){
try
{
String url="jdbc:mysql://localhost:3306/reservation?zeroDateTimeBehavior=convertToNull";
String userdb="root";
String passdb="";
Class.forName("com.mysql.jdbc.Driver");
Connection conn=DriverManager.getConnection(url,userdb,passdb);
Statement stmt=(Statement)conn.createStatement();
stmt.executeUpdate ("INSERT INTO `reserve1`( `Customer Name`, `Contact Number`, `Email Address`, `Venue`, `Date`, `Time`, `Price`, `Balance`) "+ "VALUES ("+"\""+cx1+"\""+","+"\""+contactnum11+"\""+","+"\""+email1+"\""+","+"\""+venuee+"\""+","+"\""+Date1+"\""+","+"\""+t11+"\""+","+"\""+amount1+"\""+","+"\""+bal1+"\""+")");
JOptionPane.showMessageDialog(null,"Data Added!");
}
catch( HeadlessException | ClassNotFoundException | SQLException e)
{
JOptionPane.showMessageDialog(null, e.getMessage() ,"Error", 1);
}
}
}
}
} catch (SQLException ex) {
Logger.getLogger(reservation.class.getName()).log(Level.SEVERE,
null, ex);
}

I think you should put the if(unique=true) as a separate if statement and not as the part of else if ladder.

Check whether dates are within the date range in selenium web driver ( Java)

In my website, I can select a date range and list all the transactions within the date range. My test case is to verify whether listed transactions dates are within the selected date range .
This is my code. I get all the transaction dates into a LinkedList. Comp_Dates method will compare the actual date is within the ‘From’ and ‘To’ dates.
The problem is this code will always return True. I have changed the FromDate and ToDate to test the false scenario, But still code will return True.
Can you please help? What’s the problem in this code?
//Set From Date
driver.findElement(By.id("ctl00_ContentPlaceHolderMain_container_container_Block_172_tabPanelMyAccounts_dtDateFrom_txtDate")).sendKeys(Keys.chord(Keys.CONTROL, "a"),"01/03/2016");
//Set To date
driver.findElement(By.id("ctl00_ContentPlaceHolderMain_container_container_Block_172_tabPanelMyAccounts_dtDateTo_txtDate")).sendKeys(Keys.chord(Keys.CONTROL, "a"),"30/04/2016");
driver.findElement(By.id("ctl00_ContentPlaceHolderMain_container_container_Block_172_tabPanelMyAccounts_btnList")).click();
List<WebElement> Date =
driver.findElements(By.xpath(".//* [#id='ctl00_ContentPlaceHolderMain_container_container_Block_172_tabPanelMyAccounts_stxOutstandingTransactions_gvOSTransactions']/tbody/tr[*]/td[1]"));
List<String> Dates = new LinkedList<String>();
for(int i=0;i<Date.size();i++)
{
Dates.add(Date.get(i).getText());
System.out.println(Dates);
}
boolean result = comp_Dates(Dates);
if (result=true)
{
System.out.println(result + ", Address are within the range");
}
else
{
System.out.println(result + ", Addresses are not within the range. Test Case Failed");
}
}
private static boolean comp_Dates(List<String> Dates) {
try
{
SimpleDateFormat fmt = new SimpleDateFormat("dd/MM/yyyy");
//Date date = fmt.parse("2013-05-06");
String FromDate= "01/05/2016";
String ToDate= "30/06/2016";
java.util.Date Fdate =fmt.parse(FromDate);
java.util.Date Tdate =fmt.parse(ToDate);
for(String e : Dates)
{
java.util.Date ActualDate = fmt.parse(e);
if (ActualDate.compareTo(Fdate)>=0 & ActualDate.compareTo(Tdate)<=0 );
{
return true;
}
}
}
catch (Exception ex ){
System.out.println(ex);
}
return false;
}
}
Transactions dates in Linked list is [18/04/2016, 14/04/2016, 13/04/2016]
I have specified dates as below in the code.
String FromDate= "01/05/2016";
String ToDate= "30/06/2016";
When compare these dates, code should return false as dates doesn’t fall on within From and To dates. But it returns True. What am I doing wrong here?
Thanks

When you are returning true, it will exit the function whenever it founds a date in the range. Thus it would not check for all dates in the list.
If you want to check for all dates, proper comp_Dates method could be:
//Set From Date
driver.findElement(By.id("ctl00_ContentPlaceHolderMain_container_container_Block_172_tabPanelMyAccounts_dtDateFrom_txtDate")).sendKeys(Keys.chord(Keys.CONTROL, "a"), "01/03/2016");
//Set To date
driver.findElement(By.id("ctl00_ContentPlaceHolderMain_container_container_Block_172_tabPanelMyAccounts_dtDateTo_txtDate")).sendKeys(Keys.chord(Keys.CONTROL, "a"), "30/04/2016");
driver.findElement(By.id("ctl00_ContentPlaceHolderMain_container_container_Block_172_tabPanelMyAccounts_btnList")).click();
List<WebElement> Date =
driver.findElements(By.xpath(".//* [#id='ctl00_ContentPlaceHolderMain_container_container_Block_172_tabPanelMyAccounts_stxOutstandingTransactions_gvOSTransactions']/tbody/tr[*]/td[1]"));
for (int i = 0; i < Date.size(); i++) {
String date = Date.get(i).getText();
boolean result = comp_Dates(date);
if (result) {
System.out.println(result + ", Address are within the range");
} else {
System.out.println(result + ", Addresses are not within the range. Test Case Failed");
}
}
private static boolean comp_Dates(String date) {
try {
SimpleDateFormat fmt = new SimpleDateFormat("dd/MM/yyyy");
String FromDate = "01/05/2016";
String ToDate = "30/06/2016";
java.util.Date Fdate = fmt.parse(FromDate);
java.util.Date Tdate = fmt.parse(ToDate);
java.util.Date ActualDate = fmt.parse(date);
if (ActualDate.compareTo(Fdate) >= 0 && ActualDate.compareTo(Tdate) <= 0) {
return true;
}
} catch (Exception ex) {
System.out.println(ex);
}
return false;
}
N.B: There are many typos in your code. You should fix these.

Validation when Creating an Account JAVA

So there is this certain part of my program where I can create an account and the created account will be inserted into my database. And I'm trying to code something where *refer to the code:
public void actionPerformed(ActionEvent e) {
String user = userField.getText().trim();
String pass = passField.getText().trim();
String conPass = confirmPass.getText().trim();
try{
// TODO Auto-generated method stub
if(e.getSource()==submit){
if (user.equals(user)&&pass.length()==0){
JOptionPane.showMessageDialog(null, "Fill in the empty field!");
}//check if the pass field is blank
else if(user.length()<5){
JOptionPane.showMessageDialog(null,"Username must be at least 5 characters!");
}
else if(user.equals(user)&&pass.equals(conPass)&&pass.length()!=0){
String sqlLogin = "insert into tblLogin (username,pssword) values ('"+user+"','"+pass+"')";;
getQuery(sqlLogin);
JOptionPane.showMessageDialog(null, "Account Successfully Created!");
create.dispose();
GUI gui = new GUI();
}//if(pass.equals(conPass))
else if(user.length()==0&&pass.length()==0){
JOptionPane.showMessageDialog(null, "Fill in the empty field!");
}//check if both fields are blank
else if (user.length()==0 &&pass.equals(pass)){
JOptionPane.showMessageDialog(null, "Fill in the empty field!");
}//check if user field is blank
else if(user.equals(user)&&pass!=conPass){
JOptionPane.showMessageDialog(null, "Password do not match!");
}//check if password and confirm pass matches
}
I dont really know how to say the problem but look in the if and else if statements, if the user meet one the those conditions, the program should print the JOptionPane thing. Except for the second else if.
You might be wondering why I put these codes at my else if
else if(user.equals(user)&&pass.equals(conPass)&&pass.length()!=0){
String sqlLogin = "insert into tblLogin (username,pssword) values ('"+user+"','"+pass+"')";;
getQuery(sqlLogin);
JOptionPane.showMessageDialog(null, "Account Successfully Created!");
create.dispose();
The reason for this is that, my program is having some logic error when I try to put it in if statement. Please help me with my code thanks :) Feel free to write a new code for me :DD

i might try something like this:
public static boolean isSet(String s){
if(s==null || "".equals(s)) return false;
return true;
}
//.... your validation here
if(isSet(user) && isSet(pass) && isSet(conPass) && pass.equals(conPass)){
//create account
}else{
//smth wrong eg. if(!pass.equals(conPass) { //wrongpass }
}

Data validation within data validation

I first want to validate that the user entered a value and to make sure to exit if 'cancel' was pushed. Then, I want to validate that the String releaseDateString is in the correct format at the same time as converting the String to java.sql.Date.
The first validation is taking place but then the JOptionPane carries on repeating itself and does not even consider the try and catch following it.
Here is my method
boolean retry = false;
java.sql.Date releaseDate = null;
String releaseDateString = "";
String title = "";
while (!retry) {
while(!retry){//field is validated to make sure a value was entered and to exit if cancel was pushed
releaseDateString = JOptionPane.showInputDialog("Please input the release date of the movie (yyyy-mm-dd)");
qtd.stringValidation(releaseDateString);
}
try { //the date is validated to make sure it is in the correct format
releaseDate = java.sql.Date.valueOf(releaseDateString);
} catch (Exception e) {
retry = false;
JOptionPane.showMessageDialog(null, "Make sure you enter a date in the format of 'dd-mm-yyy'");
}
}
It links to this method
public static boolean stringValidation(String attribute){
boolean retry = false;
if (attribute == null){
System.exit(0);
}
else if (attribute.equals("")) //if the cancel button is selected or no value was entered into the
{
JOptionPane.showMessageDialog(null, "Make sure you enter a character into the textbox");
}
else {
retry = true;
}
return retry;
}

When you do this,
qtd.stringValidation(releaseDateString);
You aren't assigning the result to retry. I believe you wanted,
retry = qtd.stringValidation(releaseDateString);

comparing jdatechooser with a jtextfield

Want to ask how can i compare a textfield with a JDateChooser?
if ((JTextField)jDateChooser1.getDateEditor().getUiComponent()).getText() < txtdate) {
JOptionPane.showMessageDialog(null, "Cant choose a date that is more previous >than the present date!");
} else {
JOptionPane.showMessageDialog(null, "Book Successfully Borrowed!");
}
