发一个统计项目代码行数的Java代码

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.util.ArrayList;
import java.util.List;

public class LineCounter {

List<File> list = new ArrayList<File>();

int linenumber = 0;

FileReader fr = null;

BufferedReader br = null;

public void counter(String projectName) {

String path = LineCounter.class.getResource("/").getPath(); // 同下个path

path = path.substring(0, path.length() - 24) + "/src";

// String path = "/D:/workspace/ccn/src";

System.out.println(path);

File file = new File(path);

File files[] = null;

files = file.listFiles();

addFile(files);

isDirectory(files);

readLinePerFile();

System.out.println("Totle:" + linenumber + "行");

}

// 判断是否是目录

public void isDirectory(File[] files) {

for (File s : files) {

if (s.isDirectory()) {

File file[] = s.listFiles();

addFile(file);

isDirectory(file);

continue;

}

}

}

// 将src下所有文件组织成list

public void addFile(File file[]) {

for (int index = 0; index < file.length; index++) {

list.add(file[index]);

// System.out.println(list.size());

}

}

// 读取非空白行

public void readLinePerFile() {

try {

for (File s : list) {

int yuan = linenumber;

if (s.isDirectory()) {

continue;

}

fr = new FileReader(s);

br = new BufferedReader(fr);

String i = "";
while ((i = br.readLine()) != null) {
if (isBlankLine(i))
linenumber++;
}
System.out.print(s.getName());
System.out.println("\t\t有" + (linenumber - yuan) + "行");
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (br != null) {
try {
br.close();
} catch (Exception e) {

}

}

if (fr != null) {
try {
fr.close();
} catch (Exception e) {

}
}
}
}

// 是否是空行

public boolean isBlankLine(String i) {
if (i.trim().length() == 0) {
return false;
} else {
return true;
}
}

public static void main(String args[]) {
LineCounter lc = new LineCounter();
String projectName = "ccn"; // 这里传入你的项目名称
lc.counter(projectName);
}
}


注意：最后的Main方法要传入你要统计的项目名称
