新手尝试：先在各个面板上分别开发界面，再将各个面板分别加入顶层容器contentpane.


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

public class window extends JFrame{
    //一定要extends JFrame，否则setLayout(null)后setBounds没用效果，为空白窗口
static final int WIDTH=1200;
static final int HEIGHT=900;

public static void main(String[] args) {

//主窗体
JFrame f=new JFrame();
f.setTitle("温度开关检测系统                                                                                                                                       ");
f.setSize(WIDTH,HEIGHT);
//顶层面板设置为contentpane
JPanel contentPane=new JPanel();
f.setContentPane(contentPane);

//五个下拉列表装入p1面板上
String[] s1={" COPM1","COPM2"};

JTable table=new JTable(playerInfo,Names);

//表格加入scrollpane
JScrollPane scrollpane=new JScrollPane(table);
//设置居中布局
p5.add(scrollpane,BorderLayout.CENTER);
//p5面板加入顶层容器
contentPane.add(p5);

 //组合几个面板
 contentPane.setLayout(null);
 //给几个面板设置边框
 p1.setBorder(BorderFactory.createLoweredBevelBorder());

 p3.setBorder(BorderFactory.createLoweredBevelBorder());
 p4.setBorder(BorderFactory.createLoweredBevelBorder());

     //设置各个面板的精确位置

 p3.setBounds(0, 650,400, 200);
 p4.setBounds(400, 0,800, 50);
 p5.setBounds(400, 50,800, 800);
 f.setVisible(true);
 //GridLayout gird=new GridLayout(5,1);
 //p1.setLayout(gird);
 //p1.setLayout(new FlowLayout(FlowLayout.LEFT, 30, 0));设置布局的两种方法
