import Java.io.File;

import java.io.FileWriter;

import java.io.PrintWriter;

import java.io.IOException;

public class Result {

private File result =new File("result.txt");

private FileWriter writer;

private PrintWriter pw;

public Result() {

try {

writer = new FileWriter("result.txt");

pw=new PrintWriter(writer);

}

catch (IOException iox){

System.err.println(iox);

}

}

public void aLine(String in) { //写入一行

pw.println(in);

}

public void finish() { //关闭输入流，将文字从缓存写入文件

try{

pw.flush();

writer.close();

}catch (IOException iox){

System.err.println(iox);

}

}

}
