2.核心处理统计方法。

package com.ws.dmtjtool;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;

public class CodeCounter {
public static long codeLines = 0;
public static long commentLines = 0;
public static long blankLines = 0;
public static ArrayList<File> fileArray = new ArrayList<File>();

/**
 * 可以统计指定目录下以及其子目录下的所有java文件中代码
 * 
 * @author wangshuai
 */

public static void main(String[] args) {
String path="F:/myProject/ECP-OPEN/";
path = path.replace("/", "\\");
File file = new File(path);//F:\myProject\ECP-OPEN
System.out.println(path.matches("^[A-z]:\\\\(.+?\\\\)*$"));
if(!path.matches("^[A-z]:\\\\(.+?\\\\)*$")){
System.out.println("请输入正确路径");
}
if (!file.exists()) {
  System.out.println("文件夹不存在");
}
ArrayList<File> al = getFile(file);
for (File f : al) {
if (f.getName().matches(".*\\.java$")) // 匹配java格式的文件
count(f);
}
System.out.println("代码行数：" + codeLines);
System.out.println("注释行数：" + commentLines);
System.out.println("空白行数： " + blankLines);
}

// 获得目录下的文件和子目录下的文件
public static ArrayList<File> getFile(File f) {
File[] ff = f.listFiles();
for (File child : ff) {
if (child.isDirectory()) {

} else
fileArray.add(child);
}
return fileArray;

}

// 统计方法
public static void count(File f) {
BufferedReader br = null;
boolean flag = false;

String line = "";
while ((line = br.readLine()) != null) {

blankLines++;
} else if (line.startsWith("//")) {
commentLines++;
} else if (line.startsWith("/*") && !line.endsWith("*/")) {

}
} else {

}
}
} catch (FileNotFoundException e) {
