整理一下以前学习时找到的程序。

## 一、框架 ##

## 二、代码 ##

**1、ConstantValue.java**

/*
     * 封装常量
     * */
    
    public class ConstantValue {
        
        final int row = 20; 			//行数30
        final int col = 20; 			//列数30
        final int LEICODE = 10; 		//定义雷下方的数字
        protected int temp = 20;
        protected int leiCount = 20; 	//默认雷数20
    }
