Java数组逆序读写文件实战

7、编写一个Java 程序将当100,101,102,103, 104,105个数以数组的形式写入到Dest.txt 文件 中，并以相反的顺序读出显示在屏幕上。

//programme name IODemo.java import java.io.*;

public class IODemo{

public static void main(String args\[\]){

int data\[\]={100,101,102,103,104,105};

int t;

try

{DataOutputStream out =new DataOutputStream(new FileOutputStream("dest.txt"); for(int i=0;i<data.length;i++)

out.WriteInt(datai);

out.close();

DatalnputStream in =new DataInputStream(new FileInputStream("dest.txt"));

for(int i=data.length-1;i>=0;i--){

t=in.readInt(datai);

System.out.print(" "+t);

}

System.out.println();

in.close();

}catch(IOException e)

{System.out.println(e.getMessage();}
