# 一 原始代码 #

package chapter01.java1;
    
    /**
    * 全类名：chapter01.java1.Demo
    * 全限定名：chapter01/java1/Demo
    */
    public class Demo {
        private int num = 1;
    
    
        public int add() {
            num = num + 2;
            return num;
        }
    }

# 二 Class 文件字节码 #

# 三 在 Nodepad++ 中进行整理 #

## 1 将上面的字节码拷贝到 Nodepad++ ##

## 2 初步整理后的结果如下 ##
