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(data[i]);
out.close();
DatalnputStream in =new DataInputStream(new FileInputStream("dest.txt"));
for(int i=data.length-1;i>=0;i--){
t=in.readInt(data[i]);
System.out.print(" "+t);
}
System.out.println();
in.close();
}catch(IOException e)
{System.out.println(e.getMessage();}
