我还是被

Exception in thread "main" Exit code: 1
There were errors

这个错误迷惑着啦,你能帮帮我吗,有人说我的 main 方法中

代码有误,可是我编译可以通过呀,但运行出错啦呀.

请帮我留意一下我的代码,耐心看一看,先谢谢你啦:

import java.io.*;
public class NumberInput{
public static void main(String args[]) throws IOException
{
String s;
InputStreamReader ir=new InputStreamReader(System.in);
BufferedReader in=new BufferedReader(ir);
s=in.readLine();
System.out.println("Input value is: "+s);
int i=Integer.parseInt(s);
i*=2;
System.out.println ("Input value changed after doubled:"+i);
}
}

呵呵呵呵~辛苦啦~~帮帮我哦~~给我些解决的提示哈,

等待你的回音,^-^~^-^~




Please try to use the Edit function and check "Disable Smileys".
I have corrected the typo for you.
啊啊啊~`我的代码~在我提交时~不小心~错啦一点小错误啦:
上代码中的 i=intInteger.parseInt(s);
在我原代码中是int i=Integer.parseInt(s);啦.

main中的错误应该是在其他地方啦~

我思考le很久,也查看啦代码很久,可还是百思不得其解,
在Freejava中运行的结果还是:
java.io.IOException: 句柄无效。
  at java.io.FileInputStream.readBytes(Native Method)
  at java.io.FileInputStream.read(FileInputStream.java:191)
  at java.io.BufferedInputStream.read1(BufferedInputStream.java:220)
  at java.io.BufferedInputStream.read(BufferedInputStream.java:277)
  at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:406)
  at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:446)
  at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:180)
  at java.io.InputStreamReader.read(InputStreamReader.java:167)
  at java.io.BufferedReader.fill(BufferedReader.java:136)
  at java.io.BufferedReader.readLine(BufferedReader.java:299)
  at java.io.BufferedReader.readLine(BufferedReader.java:362)
  at NumberInput.main(NumberInput.java:9)
Exception in thread "main" Exit code: 1
There were errors

对于我来说,这样de提示问题真de可大le,为什么会句柄无效呢??我只是用啦:
InputStreamReader(System.in);
我访问de资源是什么呢???为什么会无效呢????
at java.io.FileInputStream.read(FileInputStream.java:191)
其中de参数怎么是FileInputStream.java:191呢?? ":191"又是什么呀???
哎~望你能不吝赐教,不厌我烦de给一个迷糊中de菜鸟提示,
再次感谢你,你的帮助会使我在java路上少走好多弯路,剩好多时间de.

>> 有人说我的 main 方法中代码有误
不是有误，也是有误

不是句法有误
但是 main 方法 throws IOException
查一查，throws IOException 有甚么作用；
想一想，这合理吗？


似乎阁下已经设置好 JDK，于此应该不再有问题吧。
