            text = new JTextField();

                    someMethod();
                }
            });
        }
     
        private void someMethod() {
            // do what you want here
        }
    }
    Above is what I'm trying do

    I have this and it works
    switchHLbut.addActionListener(new ActionListener()
    {    
     public void actionPerformed(ActionEvent e)
    	{
       if(setBg == true){
                switchHLbut.setText("ON");
                sbc.setBackground(Color.white);
                sbc.setText("");
                setBg = false;
              }
            else if(setBg == false){
                switchHLbut.setText("OFF");
                sbc.setBackground(Color.yellow);
                sbc.setText("");
                setBg = true;
                }
        	}
    });

    but I want to call a method within the Action Listener
     
    jbNew.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e)
        {   
            System.out.println(" inside jbNew Button");
            switchjbNew();   //calling a new method
        }    
      }); //error:reached end of file while parsing
     
    public void switchjbNew()   //error: illegal start of expression missing javadoc
    { 
        System.out.println("inside switchjbNew");
    }
    this was my attempt at calling a method from within the button ActionListener
    Failed

    Default Re: ActionListener help

    Are you trying to code that method inside another method? That is not allowed. Put the method outside of the {}s that define the method the jbNew.addActionListener(new ActionListener(){ statement is in.
    If you don't understand my answer, don't ignore it, ask a question.

    I thought it was outside of any methods, It's below the button.
    Thanks.
    I have something to work with now.

    --- Update ---

    I got it, I put it right after the closing } of the constructor before

    public static void main[]
