import java.io.*;
public class RandomFileTest

	public static void main(String[] args) throws Exception
	{

乱码？

是源码还是你写的啊？

[nmyangym]

    ra.write(e1.name.getBytes());
        ra.write(e1.age);
        ra.write(e2.name.getBytes());
        ra.write(e2.age);
        ra.write(e3.name.getBytes());
        ra.write(e3.age);
        ra.close();

    ra.write(e1.name.getBytes());
        ra.writeInt(e1.age);                 //writeInt()
        ra.write(e2.name.getBytes());
        ra.writeInt(e2.age);
        ra.write(e3.name.getBytes());
        ra.writeInt(e3.age);
        ra.close();
