Thread: Assigning an 'int' from a JTextField to a variable...

I have a variable checkMate, and a jTextField, I am having problems assigning the value that I input into the jTextField to the variable checkMate. It keeps returning 0, instead of the value I enter.

private int checkMate;
 
String userTempLowB = Integer.toString(userTempLow);
 
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    saveUserSettings();
    }
 
 public void saveUserSettings(){
         userTempLowB = jTextField15.getText();
         System.out.println(""+userTempLowB);
     }

Hello, can we have more code please? Definition of jTextField15 ? any method calls on it? maybe something compilable? The reason field variable userTempLowB is being assigned when it's defined? are you sure jTextField15 is where you're typing the text?
Thanks

This code snippet doesn't show the attempt to set checkMate to anything. Are you sure you remembered to assign something to checkMate? Also, I'm sure you are aware but just in case, jtextfields getText() method returns a string. Dont forget to parse it.

I think thats the problem I am getting, do I need to say: -

checkMate = 0;

Also how do I parse it?, cos' I get a type error when I am trying to assign the value, thats why I used the Integer.toString for userTempLowB, I thought that would convert it, but I think that is wrong.

Ok, so do you have the string being properly returned? If so, to convert it, take a look at the different Integer constructors. Then if autoboxing doesn't kick in, take a look for a method that returns an int. Then assign it to checkMate.
