計算編寫代碼行數

大家算算自己的吧 ,聽說10W行以上就是高手了:-)

package my.code.counter; import java.io.BufferedReader; import java.io.File; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.IOException; import java.text.DecimalFormat; import java.util.Scanner; public class CodeCounter { static long normalLines = 0; static long commentLines = 0; static long whiteLines = 0; public static void main(String[] args) { int x; Scanner scan = new Scanner(System.in); System.out.println("自我感覺寫了多少代碼？"); x = scan.nextInt(); System.out.println("實際上（~-~#）："); File f = new File("G://code//");//代碼所在的位置 File[] codeFiles = f.listFiles(); for(File child : codeFiles){ if(child.getName().matches(".*//.java$")) { parse(child); } } System.out.println("代碼:" + normalLines); System.out.println("註釋:" + commentLines); System.out.println("空白:" + whiteLines); DecimalFormat fmt = new DecimalFormat("0.##");//保留2爲小數 System.out.println("實際和感覺的比例：" + fmt.format((double)normalLines/x*100) + "%"); System.out.println("你已經成爲" + fmt.format((double)normalLines/100000*100) + "% 的高手(10W行代碼)"); } private static void parse(File f) { BufferedReader br = null; boolean comment = false; try { br = new BufferedReader(new FileReader(f)); String line = ""; while((line = br.readLine()) != null) {//判斷是每行是什麼(代碼，註釋，空白) line = line.trim(); if(line.matches("^[//s&&[^//n]]*$")) { whiteLines ++; } else if (line.startsWith("/*") && !line.endsWith("*/")) { commentLines ++; comment = true; } else if (line.startsWith("/*") && line.endsWith("*/")) { commentLines ++; } else if (true == comment) { commentLines ++; if(line.endsWith("*/")) { comment = false; } } else if (line.startsWith("//")) { commentLines ++; } else { normalLines ++; } } } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { if(br != null) { try { br.close(); br = null; } catch (IOException e) { e.printStackTrace(); } } } } }
