Posted by: nationalist Posted on: 2006-07-28 14:12 很简单的程序 public class Hello { public static void main(String[] args) { System.out.println("HelloWorld"); System.exit(0); } } 当在命令提示符下 javac Hello.java 的时候可以编译成功生成Hello.class文件 但是当java Hello的时候它的错误提示是 Exception in thread "main" java.lang.NoClassDefFoundError:Hello 补充一下,如果我用Eclipse开发的时候就不会有这种问题出现?请问是什么原因? |
