代码统计——过滤注释空行

通常我们自己想看看自己写了多少行代码——虽然这样很冠冕堂皇，废话少说了，直接上代码：

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;

/**

public class CountRows {
private long rows = 0L;
private long chars = 0L;
private long fileNum = 0L;
private String fileType = "java";

public static void main(String[] args) throws IOException {
String path = args[0];
String fileType = args[1];
CountRows countRows = new CountRows();
countRows.setFileType(fileType);
System.out.println("开始计算目录 " + path + " 下文件的总行数...");
countRows.countRows(path);
}

public String getFileType() {
return fileType;
}

public void setFileType(String fileType) {
this.fileType = fileType;
}

public void countRows(String path) throws IOException {
File file = new File(path);
getAllFile(file);
System.out.println("统计文件数：" + this.fileNum);
System.out.println("总字符数：" + this.chars + "个");
System.out.println("总行数为：" + this.rows + " 行");
}

private void getAllFile(File file) throws IOException {
File[] files = file.listFiles();
for (File tmp : files
) {
String fileName = tmp.getName();
if (tmp.isFile() && fileName.endsWith(this.fileType)) {
long chars = tmp.length();
//System.out.println("文件名称：" + fileName);
//System.out.println("文件字符数：" + chars);
BufferedReader bufferedReader = new BufferedReader(new FileReader(tmp));
String line = "";
while ((line = bufferedReader.readLine()) != null) {
//按照编码规范剔除空行和注释行
//if (!line.trim().equals("")) {
// if(!line.trim().startsWith("/**") &&
// !line.trim().startsWith("*") &&
// !line.trim().startsWith("*/") &&
// !line.trim().startsWith("//")) {
// this.rows++;
// }
//}
this.rows++;
}
this.chars += chars;
this.fileNum++;
} else if (tmp.isDirectory()) {
getAllFile(tmp);
}
}
}
}
