java 統計代碼行數

女朋友回家了，作爲一個無聊的宅男只能自娛自樂，寫點代碼統計下我寫過多少代碼，結果有點失望，沒有想象中的上百萬行-_-

package org.yeshen;import java.io.BufferedReader;  import java.io.File;  import java.io.FileInputStream;  import java.io.IOException;  import java.io.InputStreamReader;  public class CodeCounter {static long CodeLine = 0;    public static void main(String[] args) {         File srcDir = new File("/home/yeshen/Documents/Folder/cmsmanager");         if(!srcDir.isDirectory()){              return;          }          File[] fs = srcDir.listFiles();          try {              new CodeCounter().Counter(fs);          } catch (IOException e) {              e.printStackTrace();          }        System.out.print("CodeLine:");        System.out.print(CodeLine);    }      public CodeCounter(){}    private void Counter(File[] fs) throws IOException {          for(File file:fs){              if(!file.isDirectory() ){                  if(file.getName().contains("java")){                    File p =new File( file.getParent());                    if(!p.exists()){p.mkdirs();}                    BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file),"gbk"));                     String line = br.readLine();                    while(line != null){                    if(line.trim().length() > 0){                    CodeLine ++;                      }                    line = br.readLine();                    }                    br.close();                }            }else{              Counter(file.listFiles());              }          }      }  }
