java代码统计工具

很早写的一个java代码统计，现在把代码贴上来，由于完全不会做界面，所以这个就是控制台版的了

很简单的一个类，统计的是.java和.xml(安卓的布局文件也算代码量吧)

如果遇到错误，还希望大家给我留言

Main.java
package com.io.util;

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("请输入项目文件夹地址：");
String path = scanner.nextLine();
CodeInfo codeInfo = new CodeInfo(path);
codeInfo.print();
}
}


另外打包成了jar 大家可以在控制台使用java -jar使用
