How to move another class with a button action of another class.

The contents of the button event

public void actionPerformed(ActionEvent e){
           a.kae();
  }

And make another class.

class a{
	public int test = 0;

	public void kae(){
		test=1;
		if(test==1){
			System.out.println("success");}
	}
}

Anyway, when a button event happens The value of class a changes and it passes if.
