RandomAccessFile中writeInt()的使用有关问题

RandomAccessFile中writeInt()的使用问题
package IO;
import java.io.*;
public class RandomAcessFileDemo {
  public static void main(String[] args) throws Exception {
File f=new File("D:"+File.separator+"text.txt");
RandomAccessFile raf=null;
raf=new RandomAccessFile(f,"rw");
String name=null;
int age=0;
  name="zhangsan";
age=15;
raf.writeBytes(name);
raf.skipBytes(8);
  raf.writeInt(age);
  raf.close();
  }

}
这儿使用RandomAccessFile流把字符串和int型数据写入到text.txt中
查看时，字符串没有乱码，int型数据变成了乱码。这儿该怎么解决，使
int型数据也能写入？

[解决办法]

Java code

import java.io.File;import java.io.RandomAccessFile;public class RandomAcessFileDemo {    public static void main(String[] args) throws Exception {        File f = new File("temp.txt");        RandomAccessFile raf = null;        raf = new RandomAccessFile(f, "rw");        String name = "zhangsan";        Integer age = 15;        raf.writeBytes(name);        raf.skipBytes(8);        raf.writeInt(age);        raf.seek(0);//找位置        byte[] b = new byte[8];        raf.read(b);        System.out.println(new String(b));        System.out.println(raf.readInt());        raf.close();    }}
