1.java.io.IOException: 句柄无效??? | Copy to clipboard |
Posted by: aideliwu Posted on: 2004-09-01 14:15 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~ |

Posted by: aideliwu Posted on: 2004-09-01 21:32 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. |

Posted by: why Posted on: 2004-09-03 09:21 >> 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。 敝人不常在 J2SE 版出现,有事勿找敝人。 (这裡有不少热心助人的会员,多向大家学习好了。 当然,先搜尋旧帖子。) ) |
