上篇文章大家熟悉了JPanel容器的使用，下面將通過程序?qū)嵗菔舅氖褂梅椒?，?a target="_blank" rel="nofollow">代碼如下:

publicclassBWF{

publicstaticintWIDTH=300;

publicstaticintHEIGHT=250;

publicstaticvoidmain(Stringargs[]){

JFramejf=newJFrame("測試JPanel");

jf.setSize(WIDTH,HEIGHT);

jf.setLayout(newBorderLayout());

//創(chuàng)建6個中間容器，并且將contentPane放到頂層容器內(nèi)

JPanelcontentPane=newJPanel();

JPanelp1=newJPanel();

JPanelp2=newJPanel();

JPanelp3=newJPanel();

JPanelp4=newJPanel();

JPanelp5=newJPanel();

//創(chuàng)建9個普通按鈕組件，將P1到p5個面板設(shè)置為流布局

JButtonb1=newJButton("1");

JButtonb2=newJButton("2");

JButtonb3=newJButton("3");

JButtonb4=newJButton("4");

JButtonb5=newJButton("5");

JButtonb6=newJButton("6");

JButtonb7=newJButton("7");

JButtonb8=newJButton("8");

JButtonb9=newJButton("9");

FlowLayoutf1=newFlowLayout();

FlowLayoutf2=newFlowLayout();

FlowLayoutf3=newFlowLayout();

FlowLayoutf4=newFlowLayout();

FlowLayoutf5=newFlowLayout();

p1.setLayout(f1);

p2.setLayout(f2);

p3.setLayout(f3);

p4.setLayout(f4);

p5.setLayout(f5);

//將b1,b2加到P1中，將b3,b4加到p2中

//將b5,b6加到P3中，將b7,b8加到p4中,將b9加到p5中

p1.add(b1);

p1.add(b2);

p2.add(b3);

p2.add(b4);

p3.add(b5);

p3.add(b6);

p4.add(b7);

p4.add(b8);

p5.add(b9);

contentPane.add(p1,BorderLayout.NORTH);

contentPane.add(p2,BorderLayout.SOUTH);

contentPane.add(p3,BorderLayout.EAST);

contentPane.add(p4,BorderLayout.WEST);

contentPane.add(p5,BorderLayout.CENTER);

jf.setContentPane(contentPane);

jf.setVisible(true);

}
