向文件中写东西

package com.company;
import java.io.*;
import java.nio.charset.StandardCharsets;
import java.util.Scanner;
public class Main {

    public static void main(String[] args) {
   // write your code here
        Scanner scanner=new Scanner(System.in);//建立一个从键盘输入的扫描器
        FileOutputStream fos=null;
        try{
            fos=new FileOutputStream("D:\\练习.txt");
            String str=scanner.next();
            fos.write(str.getBytes());

        }catch(IOException e)
        {
            e.printStackTrace();
        }finally{
            try{
                fos.close();
            }catch(IOException e)
            {
                e.printStackTrace();
            }
        }
    }
}
