Swing 空布局

试了盒布局，说实话不太会用，很多地方都没法更加的细节，又翻了翻资料，知道了还有一个空布局，一看，真不错，很适合我这种菜鸡

用坐标就可以完成界面的布局，不错

话不多说，直接代码

package ui;

import javax.swing.*;

public class TestDemoNull extends JFrame {

    JPanel jp=new JPanel();    //创建面板
    JLabel label1=new JLabel("地点");    //创建标签
    JComboBox cmb=new JComboBox();    //创建JComboBox
    JButton btn0=new JButton("夜泊秦淮 ice paper");
    JButton btn1=new JButton("月光不解风情");
    JButton btn2=new JButton("行人故作冷静");
    JButton btn3=new JButton("夜色更难分明");
    JButton btn4=new JButton("一丝一扣朦胧了倒映");
    JButton btn5=new JButton("你背影何处寻");
    JButton btn6=new JButton("愁眉啼妆难平");
    JButton btn7=new JButton("如烟遮望眼");
    JButton btn8=new JButton("飞鸟随风乱了序");
    JButton btn9=new JButton("*这不比丫的流量明星好听*");


    /********************************************/

    TestDemoNull() {
        cmb.addItem("");    //向下拉列表中添加一项
        cmb.addItem("北京");
        cmb.addItem("上海");
        cmb.addItem("深圳");
        JRadioButton  chkbox1=new JRadioButton ("ice");    //创建指定文本和状态的复选框
        JRadioButton  chkbox2=new JRadioButton ("paper");    //创建指定文本的复选框
        JRadioButton  chkbox3=new JRadioButton ("yyds",true);    //创建指定文本的复选框
        jp.add(chkbox1);
        jp.add(chkbox2);
        jp.add(chkbox3);

        /********************************************/

        this.add(btn0);
        this.add(btn1);
        this.add(btn1);
