First GUI program

[Manny Ruiz]

Que Angelic Music....thank you thank you thank you thank you. I think this will work out fine. and the best part was I feel like even though I may not fully understand how it all works, I now have a working model I can refer too. Only thing I need to work on is getting the clear button to work but check it out.

 public class addex extends JFrame {  
     private JLabel num1;  
     private JLabel num2;  
     private JLabel answer;  
     private JTextField number1;  
     private JTextField number2;  
     private JTextField answerfield;  
     private JButton add;  
     private JButton clear;  
     private JButton exit;  
     private JPanel contentpanel;  
     private String x, y;  
     private ActionListener listener;  
       
     private void addelement(Container c, Component e, int x, int y, int h, int w){  
         e.setBounds(x, y, h, w);  
         c.add(e);  
     }  
     addex(){  
         contentpanel = (JPanel)getContentPane();  
         contentpanel.setLayout(null);  
         num1 = new JLabel ("First Number");  
         addelement(contentpanel, num1, 0,0,100,20);  
         num2 = new JLabel ("Second Number");  
         addelement(contentpanel, num2, 0,30,100,20);  
         answer = new JLabel ("Answer");  
         addelement(contentpanel, answer, 0,60,100,20);  
         number1 = new JTextField();  
         addelement(contentpanel, number1, 105, 0, 100, 20);  
          
         number1.addActionListener(listener);  
         number2 = new JTextField();  
         addelement(contentpanel, number2, 105, 30, 100, 20);  
         answerfield = new JTextField();  
          
         number1.addActionListener(listener);  
         addelement(contentpanel, answerfield, 105, 60, 100, 20);  
         add = new JButton ("Add");  
         addelement(contentpanel, add, 0, 120, 100, 20 );  
         add.addActionListener(new ActionListener(){  
             public void actionPerformed(ActionEvent e){  
                 addition();  
             }  
         });  
         clear = new JButton ("Clear");  
         addelement(contentpanel, clear, 0, 160, 80, 20 );  
         exit = new JButton ("Exit");  
         addelement(contentpanel, exit, 100, 160, 80, 20 );  
         exit.addActionListener(new ActionListener(){  
             public void actionPerformed(ActionEvent e){  
                 System.exit(0);  
             }  
         });  
         setTitle("GUI TEST");  
         setSize(250, 250);  
         setLocation(new Point(150,150));  
         setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);  
         setVisible(true);     
     }  
       
     private void addition() {  
    	 x = number1.getText(); 
    	 y = number2.getText(); 
    double numb1 = Double.parseDouble(x);  
    double numb2 = Double.parseDouble(y);  
    double ans = numb1+numb2;  
    
     answerfield.setText(String.valueOf(ans));  
         }  
       
     public static void main(String args []){  
         new addex();  
         }  
    }

Good job! Glad you're happy with it.

Clear is easy, just set the text in that field to "".

If you come back for help with your next assignment, please start your next project in a new thread.

I'll be looking out for you.

creating the clear was by far the easiest thing to do...since now i understand a lot better of whats going on. Thank for all you help. I will probably need help in my next assignment so hope to see you again
