I want to change a boolean attribute, based in main class, through a constructor. This is the code:

public class NewJDialog{

    public boolean CHECK;
    java.awt.Label label;
.
.
.
    Trasporta valore = new Trasporta(CHECK,label);
.
.
.
}

Class2 

public class Trasporta implementsMouseListener,MouseMotionListener{



public  boolean value;

java.awt.Label label;



public Trasporta(boolean value, java.awt.Label ... pns){

    for ( java.awt.Label genericlabel : pns){
         genericlabel.addMouseListener(this);
         genericlabel.addMouseMotionListener(this);             
    }

   this.value=value;
}




@Override
public void mousePressed(MouseEvent e) {


    this.value = true;
}

In this way, CHECK attribute will not become "true".

Can you tell me why? How can I fix it?

Thanks in advance for your reply.

You declare CHECK as primitive type, and not initialize it so it will have default value (primitive boolean are initialized as false)

Change your code to 

Trasporta valore = new Trasporta(true,label);

if you want to initialize Transporta class with value = true;

Also, you should read this paper about naming convenction in java https://www.oracle.com/technetwork/java/codeconventions-135099.html

  • that is not answering the question, OP wants to change the value (i`CHECK`) from another later called method (`mousePressed`) - I suppose – user85421 Apr 25 '19 at 17:18
