randomtester.java

接着上次传入一些Java学习中的实验

import java.io.*;
public class RandomTester{
	public static void main(String args[])throws IOException{
	RandomAccessFile rf=new RandomAccessFile("D:\\javaprogram\\test.dat","rw");
	for(int i=0;i<10;i++)
	rf.writeLong(i*1000);
	
	rf.seek(5*8);
	rf.writeLong(1234);
	
	rf.seek(0);
	for(int i=0;i<10;i++)
	System.out.println("value"+i+":"+rf.readLong());
	
	rf.close();
	}
