System.in问题:错误是Unhandled exception type IOException

摘要: System.in问题:错误是Unhandled exception type IOException

import java.util.*;
import java.io.*;
public class wo{

public static void main(String arg[]){

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
int i = Integer.parseInt(in.readLine());
}
}
错误是Unhandled exception type IOException
是这里in.readLine()
这是什么问题啊？

IOException没有处理

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

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
int i = Integer.parseInt(in.readLine());
}

---

public static void main(String arg[]) throws Exception
{
try{
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
int i = Integer.parseInt(in.readLine());
}
catch(IOException e)
{
//Error Handle....
}
}

哦，第二个就去掉public static void main(String arg[]) throws Exception后面的throws Exception：）

谢谢，好了！！！
