Posted by: philipshot Posted on: 2006-02-27 08:54 应该是你的JCreator的问题! 卸了重装! 装好,第一次运行的时候,会提示连接到j2sdk安装的路径, 一般会自动找到的, 要不就手动连接到你装j2sdk的路径! ) 还有char c= ''; 可能编译时会有问题 char c= ' '; 我认为加个space就可以了.

Posted by: newobject Posted on: 2006-02-27 15:55 JCreator重装,我以前也有过这样的事情! char c= '';这个地方好像也有错吧! 我也是个Java新手,希望大家可以一起交流QQ361451916

Posted by: Skybus Posted on: 2006-02-27 23:43 在JCreator的configure菜单项中指定你所安装的java jdk目录。另外char c='';并不是给c赋空值，可以用空格代替或者干脆不赋值！

我在Configure 里设置过了路径，而且好象已经可以编译了，只是又出现了以下问题：

import java.io.*;
public class BasicInOutApplication{

   public static void main(String args[])
   {
      char c= ' ';
      System.out.print("Enter a character please:");
      try{
        c=(char)System.in.read();
        }catch(IOException e){
          System.out.println Envelope

;
        }
        System.out.println("You entered character:" + c);
   }
}

错误：：--------------------Configuration: J2SDK1.4.2 <Default>--------------------
D:\JCreator Pro\MyProjects\name\name\BasicInOutApplication.java.java:3: class BasicInOutApplication is public, should be declared in a file named BasicInOutApplication.java
public class BasicInOutApplication{
^
1 error

Process completed. 怎么回事啊？？！

Posted by: 茂珊 Posted on: 2006-03-01 15:43 class BasicInOutApplication is public, should be declared in a file named BasicInOutApplication.java 这是什么意思啊！！很好懂吗？我不太明白啊！能告诉我吗？

Posted by: Skybus Posted on: 2006-03-01 19:49 class BasicInOutApplication is public, should be declared in a file named BasicInOutApplication.java 就是说你的java文件的文件名必须与文件中被声明为public的java类的名字相同, btw: 一个java程序中只有一个public类,也就是说你的java程序的名字必须为 BasicInOutApplication.java.

Posted by: jackyangf Posted on: 2006-03-21 17:01 不过char c = '';真的可以吗？
