String Array for JApplet

  1. Feb 27, 2017 #1
    I don't know how to display what the string you see in the array. Do I need to put something in the paint method? It's annoying because my book and everywhere I look only show examples using integers and not strings.

    This code is in the init method. I can't find out where to display the "dog", "cat", etc into the applet itself.

    Code (Text):
     String [][] name = {{"dog"}, {"cat"}, {"bridge"}, {"lake"}};
    Code (Text):
    import java.awt.*;
    import javax.swing.*;
    import java.awt.event.*;
    import java.util.Arrays;
    import java.applet.*;
    import java.awt.Graphics;

    public class DictionaryTest extends JApplet implements ActionListener

    {
         JLabel label;
         //declaring and creating array of objects/buttons using intiailizer list
        TextField tf;
        JButton[ ] mybuttons =
        {
                new JButton( "one" ),
                new JButton( "two" ),
                new JButton( "three" ),
                new JButton( "four" )
        };
       
        public void init( )
        {
            setLayout( new FlowLayout( )  );
       
            tf = new TextField(15);
            add(tf);
           
            String [][] name = {{"dog"}, {"cat"}, {"bridge"}, {"lake"}};
            for( int x=0; x < mybuttons.length; x++ )
            {
                mybuttons[x].addActionListener(this);
                add( mybuttons[x] );
            }
        }
        public void paint(Graphics g){
                super.paint(g);
        }
        public void actionPerformed( ActionEvent ae )
        {
            Object obj = ae.getSource( );
            if( obj == mybuttons[0] )
            {
                label.setText( "first button" );
            }
            else if ( obj == mybuttons[1] )
            {
                label.setText( "second button" );
            }
            else if( obj == mybuttons[2] )
            {
                label.setText( "third button" );
            }
            else if( obj == mybuttons[3] )
            {
                label.setText( "fourth button" );
            }
        }
    }

    I believe that you need code in your paint() method. You should be able to use the String class's write method to write a string.

    Regarding your array, you shouldn't be using a two-dimensional array for your strings.

    The declaration should look like this:
    Code (Java):
    String [] name = {"dog", "cat", "bridge", "lake"};
    name[0] is "dog", name[1] is "cat" and so on.
    Actually, the array is just a list of addresses, with each address being the location of the first character in one of the strings.

    Thanks for the help. I'll work on it.
