Java Basic(65)-The Final Check Box Program

Continue Java Basic(64)

private class HandlerClass implements ItemListener{

public void itemStateChanged(ItemEvent event){

Font font = null;

if(boldbox.isSelected() && italicbox.isSelected())

font = new Font("Serif", Font.BOLD + Font.ITALIC, 14);

else if(boldbox.isSelected())

font = new Font("Serif", Font.BOLD, 14);

else if(italicbox.isSelected())

font = new Font("Serif", Font.ITALIC, 14);

else

font = new Font("Serif", Font.PLAIN, 14);

tf.setFont(font);

}

}

The apples.java is same:

import javax.swing.JFrame;

class apples{

public static void main(String[] args){

Gui go = new Gui();

go.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

go.setSize(400, 200);

go.setVisible(true);

}

}

然後運行，你可以在checkbox，並改變字體為粗體和斜體
