java程序设计帮我分析一下每句话的意思好吗

import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
public class HandleMove extends JPanel implements MouseListener,ActionListener {
Point [][] point;
int spendTime=0;
javax.swing.Timer recordTime;
JTextField showTime;
VerifySuccess verify;
HandleMove(){
recordTime=new javax.swing.Timer(1000,this);
showTime=new JTextField(16);
showTime.setEditable(false);
showTime.setHorizontalAlignment(JTextField.CENTER);
showTime.setFont(new Font("楷体_GB2312",Font.BOLD,16));
JLabel hitMess=new JLabel("用鼠标单击方块",JLabel.CENTER);
hitMess.setFont(new Font("楷体_GB2312",Font.BOLD,18));
add(hitMess);
add(showTime);
setBackground(Color.cyan);
}
public void setPoint(Point [][] p){
point=p;
}
public void initSpendTime(){
recordTime.stop();
spendTime=0;
showTime.setText(null);
}
public void setVerifySuccess(VerifySuccess verify){
this.verify=verify;
}
public void mousePressed(MouseEvent e){

public void mouseExited(MouseEvent e){}
public void mouseClicked(MouseEvent e){}
}

Answer 1

说一下大致的吧：
1.import引入包，下面会用到
2.public class HandleMove extends JPanel implements

MouseListener,ActionListener {
//创建HandleMove类并继承JPanel并实现MouseListener,ActionLister接口
2. Point [][] point;
int spendTime=0;
javax.swing.Timer recordTime;
JTextField showTime;
VerifySuccess verify;
//声明变量，各个类型地，这里的变量类型就是引入包import

javax.swing.*; 这里的
3.HandleMove(){
recordTime=new javax.swing.Timer(1000,this);
showTime=new JTextField(16);
showTime.setEditable(false);
showTime.setHorizontalAlignment(JTextField.CENTER);
showTime.setFont(new Font("楷体_GB2312",Font.BOLD,16)); //设

置字体
JLabel hitMess=new JLabel("用鼠标单击方块",JLabel.CENTER);//

设置JLabel标签
hitMess.setFont(new Font("楷体_GB2312",Font.BOLD,18)); //设置

字体
add(hitMess); //添加到Jpanel面板
add(showTime); //添加到Jpanel面板
setBackground(Color.cyan); //设置面板背景颜色
}
//定义构造器,并创建各个组件
4.下面就是创建各类方法
用于实现各个功能点
