Answer 2

Container cp=getContentPane();
cp.setLayout(new GridLayout(4,3);
JButton btn1=new JButton("1");
JButton btn2=new JButton("2");
JButton btn3=new JButton("3");
JButton btn4=new JButton("4");
JButton btn5=new JButton("5");
JButton btn6=new JButton("6");
JButton btn7=new JButton("7");
JButton btn8=new JButton("8");
JButton btn9=new JButton("9");
JLabel lab=new JLabel("结果");
JTextField textInput=new JTextFiled(30);
cp.add(btn1); cp.add(btn2); cp.add(btn3);
cp.add(btn4); cp.add(btn5); cp.add(btn6);
cp.add9btn7); cp.add(btn8); cp.add(btn9);
cp.add(lab);cp.add(textInput);
setVisible(true);
这样就可以了

Answer 4

我已经测试过了，和你要的一样，还是你自己看吧：
import java.awt.*;

public class ButWin extends Frame {
private Button[] btns;
private int totalBtns;
private Label lb;
private TextField txd;

public ButWin()
{
setLayout(new BorderLayout());

GridLayout gl = new GridLayout(3,3);
Panel btnPanel = new Panel(gl);
gl.setHgap(5); //设置按钮间的水平间距
gl.setVgap(5); //设置按钮间的垂直间距
btnPanel.setBackground(Color.white);

totalBtns = 9;
btns = new Button[totalBtns];
for(int i = 0; i < totalBtns; i++)
{
btns[i] = new Button("button" + (i + 1));
btnPanel.add(btns[i]);
}

Panel resPanel = new Panel();
resPanel.setBackground(Color.white);

lb = new Label("结果");
txd = new TextField(10);
resPanel.add(lb);
resPanel.add(txd);

add(btnPanel,BorderLayout.CENTER);
add(resPanel,BorderLayout.SOUTH);
}

public static void main(String[] args)
{
ButWin frm = new ButWin();

frm.pack();
frm.setVisible(true);
}
}

人家要的是AWT做的，你们做的都是swing
都不看题啊！！
