此段代码有何问题

Question

import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;import com.sun.org.apache.bcel.internal.generic.NEW;public class ZijieInput { /**
 * 利用 字节流 类DataInputStream和FileInputStream 读二进制文件
 */
public static void main(String[] args){
//构造DataInputStream 对象
FileInputStream fStream=null;
DataInputStream dStream=null;
try {
 fStream=new FileInputStream("ZifuReader.class");
 dStream=new DataInputStream(fStream);
 //读取
 try {
while(dStream.readInt()!=-1){
 System.out.println(dStream.readInt());
 }
} catch (IOException e) {
System.out.println("文件读取或写入有误"+e.getStackTrace());
}
} catch (FileNotFoundException e) {
System.out.println("错误：没有找到文件");
}finally{
//关闭相关的流
try {
dStream.close();
fStream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}

Answer 1

while(dStream.readInt()!=-1){ 
System.out.println(dStream.readInt()); 
} 
每次操作相当于读了两次
应该
int data;
while((data=dStream.readInt())!=-1){ 
System.out.println(data);  
} 
至于不能二进制的问题就看你自己了

Answer 2

while(dStream.readInt()!=-1){ 
System.out.println(dStream.readInt());
这里！！！同意5楼
