让FlowLayout的布局的排列方向竖着来

在网上找了很多怎么让FlowLayout的布局的排列方向竖着来，就索性自己在容器里面嵌套一个面板，嵌套的面板用GridLayout布局，在嵌套的面板理面添加组件

代码如下：

import java.awt.Container;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import java.awt.Panel;
import java.awt.TextField;


import javax.swing.BoxLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;
public class JTextFieldDemo extends JFrame{
private JTextField tetField_3;
private JTextField tetField_2;
private JTextField tetField_1;
private JTextField tetField;
public JTextFieldDemo(){
super();
Container c=getContentPane();
final FlowLayout flowLayout_4=new FlowLayout();
flowLayout_4.setAlignment(FlowLayout.LEFT);
c.setLayout(flowLayout_4);
setTitle("文本框演示程序");
setBounds(100,100,412,166);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
c.setLayout(flowLayout_4);
Panel panel=new Panel();
Panel panel_1=new Panel(new GridLayout(4,0,-100,10));//嵌套的GridLayout布局
Panel panel_5=new Panel(new GridLayout(4,2,0,15));//嵌套的GridLayout布局
panel_1.add(new JLabel("姓名： "));
JTextField textField=new JTextField();
panel_1.add(textField);
panel_1.add(new JLabel("性别： "));
tetField_1=new JTextField(4);
panel_1.add(tetField_1);
panel_1.add(new JLabel("年龄： "));
tetField_2=new JTextField("20");
panel_1.add(tetField_2);
panel_1.add(new JLabel("住址： "));
tetField_3=new JTextField("吉林省长春市",12);
panel_1.add(tetField_3);
c.add(panel_1);
panel_5.add(new JLabel("JTextField()"));
panel_5.add(new JLabel("JTextField(int columns)"));
panel_5.add(new JLabel("JTextField(String text)"));
panel_5.add(new JLabel("JTextField(String text,int columns)"));
c.add(panel_5);
setVisible(true);
}
public static void main(String[] args){
new JTextFieldDemo();
}
}
