Java中如何将List中剩下的人名逐行写回原来的TXT文件

package org.ccid.test;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

/**

public class ReadName {
public static void main(String[] args) throws Exception{
FileInputStream fileRead = new FileInputStream(new File("D:\\name.txt"));
InputStreamReader inputStreamReader = new InputStreamReader(fileRead,"UTF-8");
BufferedReader buffer = new BufferedReader(inputStreamReader);
String tempStr = "";
List list = new ArrayList();
System.out.println("所有人名如下：");
while((tempStr=buffer.readLine())!=null) {
System.out.println(tempStr);
list.add(tempStr);
}
System.out.println("-------------------------");

//每次随机删除三个人名
System.out.println("删除的人名如下：");
for (int i = 0; i < 3; i++) {
int tempIndex = (int)(Math.random()*4);
System.out.println(list.get(tempIndex));
list.remove(tempIndex);
}
System.out.println("--------------------------");
System.out.println("剩下的人名如下:");
for (int i = 0; i < list.size(); i++) {
System.out.println(list.get(i));
}
}
}



现在问题是如何将剩下的人名逐行写回原来的TXT文件（覆盖掉原来的）
