去掉注释

代码注释很重要，没有注释的代码简直就是噩梦。可就是有人想要没注释的源码，真无奈。。。

写了个小工具，去掉java中的代码注释，奉上。其实很简单，就是一些递归，遍历，IO

 

package mxf.study.java;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

public class RemoveJavaDoc {

private int count;
static String destPath = "C:/Java/src";
static String srcPath = "C:/Java/jdk1.6.0_22/src";

static {
File destPathFile = new File(destPath);
if(!destPathFile.exists()){
destPathFile.mkdir();
}
}
public static void main(String[] args) throws IOException {

RemoveJavaDoc rjd = new RemoveJavaDoc();
rjd.findFile(new File(srcPath));
System.out.println(rjd.count);
}

private void findFile(File file) throws IOException {
if (file.isDirectory()) {
String destFileName = destPath
+ file.getAbsolutePath().substring(23);
new File(destFileName).mkdir();
for (File f : file.listFiles()) {
findFile(f);
}
} else {
count++;
String destFileName = destPath
+ file.getAbsolutePath().substring(23);
System.out.println(destFileName);

FileReader r = new FileReader(file);
BufferedReader br = new BufferedReader(r);
String line = null;
BufferedWriter bw = null;
try {
FileWriter w = new FileWriter(destFileName);
bw = new BufferedWriter(w);

boolean isDocLine = false;
boolean isBlank = false;
while ((line = br.readLine()) != null) {

if (line.contains("//")){
line = line.substring(0, line.indexOf("//"));
}

if(isDocLine && !line.contains("*/")) continue;

if (line.contains("/*")) {
if (line.contains("*/")) {
line = line.substring(0, line.indexOf("/*"))

} else {
isDocLine = true;
line = line.substring(0, line.indexOf("/*"));
}
}

if(line.contains("*/") && !line.contains("/*")){
line = line.substring(line.indexOf("*/") + 2);
isDocLine = false;
}

bw.write(line + "\r\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
br.close();
bw.close();
}
}
}
