Java编程：比对两个文本文件，标记相同和不同之处

使用需求：

文件1里面是需要比较的内容，文件2是被比较的文本，现在需要找到在文件1中每一行的文本在文件2中是否存在并相等，如果相等，就在一份结果文件中输出，文件1的哪一行与文件2的哪一行相同，反之不相同就输出文件1的哪一行不相同货不存在。

Java代码如下，输出的是result.txt文件，这个文件的行号和文件1保持一致，所以result中某一行的结果就是对应的文件1中这行数据在文件2中比较之后的结果。

（需要注意文件1和文件2是通过每一行的内容进行比较）

最后为了方便查看可以通过Notepad++查看：如图：

package com.it.aron;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
