How to check another button while action performed

Question

I have 2 buttons, when first button is clicked, it runs an infinite loop and I want it to stop when i click the second button. What is the proper way to do this since I'm new on using java.

I know this wrong but I just want to make clear what I'm trying to do

private void button1_buttonActionPerformed(java.awt.event.ActionEvent evt) {
    while( !button2.isClicked() ) {} }

here's what i have try

boolean sthap = false;
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         

   while(!sthap){
   System.out.println("run");
   }
}                                        

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    sthap=true;
}

Answer 1

define a flag variable like;

boolean isBUttonClicked = false;

and in your while loop

use if statement like

while(true){
   if(isButtonClicked){
     isButtonClicked = false;
     break;
   }else{
      //do your job
   }
}

in the second button action performed method

use isButtonClicked and make it true like

isButtonClicked = true;

Answer 2

Try this

boolean sthap = false;

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    new Thread(new Runnable() {
        @Override
        public void run() {
            while (!sthap) {
                System.out.println("run");
            }
        }
    }).start();
}

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
    sthap = true;
}

Answer 3

Declare a static variable like this boolean flag=false outside the button methods. Then inside button 1,

private void button1_buttonActionPerformed(java.awt.event.ActionEvent evt) { while( !flag ) {} }

and inside button2,

private void button1_buttonActionPerformed(java.awt.event.ActionEvent evt) { flag = true}
