问题描述
你好
我在一个名为 hamzah 的程序包中有一个名为 Hamzah 的类，我尝试从命令行运行它，但始终有 NoClassDefFoundError 该类正确编译，并且.class文件已生成，但没有运行
我尝试执行以下操作:
Hello
i have a class called Hamzah inside a package called hamzah i tried to run it from Command line but always i have NoClassDefFoundError the class compiled correctly and .class file produced but it didn''t run
i try to do the following :
<br />
<C:\Users\h.khammash\Desktop\Studening workspace\TestCmd\src\com\hamzah>javac Hamzah.java>
编译成功
这是要运行的:
C:\Users\h.khammash\Desktop\Studening workspace\TestCmd\src\com\hamzah>java -cp . Hamzah
在这里出错.
Compiled successfully
and this for run :
C:\Users\h.khammash\Desktop\Studening workspace\TestCmd\src\com\hamzah>java -cp . Hamzah
Error here .
推荐答案
java Hamzah
假定Hamzah具有有效的main方法.
假设您的课程在软件包com.hamzah中，请从src目录构建并运行:
This assumes Hamzah has a valid main method.
Assuming your class is in package com.hamzah, build and run from the src directory:
C:\Users\h.khammash\Desktop\Studening workspace\TestCmd\src>javac com\hamzah\Hamzah.java
C:\Users\h.khammash\Desktop\Studening workspace\TestCmd\src>java com.hamzah.Hamzah
C:\Users\h.khammash\Desktop\Studening workspace\TestCmd\src\com>java hamzah.Hamzah
// or
java hamzah/Hamzah
