I decided I did not like the background colour of my frame so I added the line shown in bold italics, compiled it and ran it:
andrew@UBUNTU:~/Java$ cat AndrewsFrame.java
import java.awt.*;
public class AndrewsFrame extends Frame
{
public AndrewsFrame()
{
super("Andrew's Frame");
setSize(500,300);
setBackground(Color.red);
setVisible(true);
}
public static void main (String args[])
{
AndrewsFrame af = new AndrewsFrame();
}
}
andrew@UBUNTU:~/Java$ javac AndrewsFrame.java
andrew@UBUNTU:~/Java$ java AndrewsFrame
This time the background was red (as usual, click on the image to enlarge it and bring it into focus):
import java.awt.*;
public class AndrewsFrame extends Frame
{
public AndrewsFrame()
{
super("Andrew's Frame");
setSize(500,300);
setBackground(Color.red);
setVisible(true);
}
public static void main (String args[])
{
AndrewsFrame af = new AndrewsFrame();
}
}
