Repaint method not working from button call

[Sam Nassiri]

Dear all,

I have constructed a button that when pressed calls a method to repaint a JFrame. The repaint is called from a method called refresh, which is placed inside a for loop. The intended result is that the JFrame is refreshed at the end of each loop, i.e. 5 times if x is equal to 5. Unfortunately the repaint only happens at the end of the for loop, and only one change is observed. Below is the code.

class listen_2 implements ActionListener{
           	
    	public void actionPerformed(ActionEvent event){
     		
    		thisSimulation.runProcess(20);
    	
    	}

public void runProcess(int days){
   	
   	  for(int x = 0; x < days; x++){
	  		
	  		System.out.println("Loop is on day " + x);
	  		System.out.println(" ");
	  		System.out.println("DAY " + x);
	  		System.out.println(" " );
	  		System.out.println("****************************" );
	 		thisGod.run();
	 		thisSession.refresh();
	 		delay(500);
	
	   }

The repaint() method is contained within thisSession.refresh().

Many Thanks
Sam
