java中的输入输出的小问题

Question

代码如下：
package com;
import java.io.*;
public class Example16 {
public static void main(String args[]){
int bytes[]={1,2,3,4,5};
try{
RandomAccessFile raf=new RandomAccessFile("D:\Example9.txt","rw");
for(int i=0;i raf.writeInt(bytes[i]);
}
for(int i=bytes.length-1;i>=0;i--){
raf.seek(i*4);
System.out.println(raf.readInt());

        }
        raf.close();
    }catch (IOException e){
        e.printStackTrace();
    }
}

}
为什么写入txt文件中不是12345而是几个小方块呢？
求高手解答。

Answer 1

package com;

import java.io.*;

public class Example16 {
public static void main(String args[]) {
int bytes[] = { 1, 2, 3, 4, 5 };
try {
RandomAccessFile raf = new RandomAccessFile("D:\Example9.txt","rw");
for (int i = 0; i < bytes.length; i++) {
raf.writeBytes(String.valueOf(bytes[i]));
}
for (int i = bytes.length - 1; i >= 0; i--) {
raf.seek(i * 4);
}
System.out.println(raf.readLine());

        raf.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

}
跟字节有关
