写一个线程，遍历G盘一个目录下的所有文件和目录，并将这些信息写入G盘的一个文件中

Question

代码如下，生成的新文件中没有写入任何信息，请高手们帮忙看看

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

public class Demo {
public static void main(String[] args){
new Thread(new MyThread()).start();
}
}

class MyThread implements Runnable{

@Override
public void run() {
    // TODO Auto-generated method stub
    File existFile = new File("G:\\zhuo");
    File newFile = new File("D:\\content.txt");
    try {
        System.out.print(newFile.createNewFile());
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        System.out.print("create error");
    }
    try {
        writeNewFile(existFile,newFile);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        System.out.print("write error");
    }
}

public void writeNewFile(File g,File newFile) throws Exception{
    BufferedWriter bw= new BufferedWriter(new FileWriter(newFile.getName()));
    File[] files = g.listFiles();
    for(File file:files){
        if(file.isFile()){
            bw.write(file.getName());
            bw.newLine();
            bw.flush();
        }
        else{
            bw.write(file.getName());
            bw.newLine();
            bw.flush();
            writeNewFile(file,newFile);
        }
    }
    bw.close();
}

}
