② JAVA編寫一個窗口（frame），要求窗口中有文本框,按鈕,標簽,單選框,復選框,

import javax.swing.*;
import java.awt.*;

public class test extends JFrame{
public test(){
JButton button; //按鈕
JLabel label; //標簽
JComboBox combobox;//下拉菜單
JCheckBox checkbox;//復選框
JRadioButton radiobutton;//單選框
JTextField textfield;//文本框

button = new JButton("按鈕");
label = new JLabel("標簽：");
checkbox = new JCheckBox("復選框一");
radiobutton = new JRadioButton("單選框一");
combobox = new JComboBox();
textfield = new JTextField(100);

Container c = this.getContentPane();
c.setLayout(new FlowLayout());
c.add(button);
c.add(label);
c.add(checkbox);
c.add(radiobutton);

combobox.addItem("1");
combobox.addItem("2");
c.add(combobox);

c.add(textfield);

setSize(300, 200);
setVisible(true);
}
public static void main(String[] args) {
// TODO 自動生成方法存根
test mytest = new test();
}

}
