Question

我正在使用Dr.Java，当我运行程序时我得到了错误，但是在另一个非常类似的程序上，错误消失并且正常符文。

欢迎来到DrJava。工作目录是E：\ Inheritance 运行员工静态错误：此类没有接受String []的静态void main方法。 “欢迎来到DrJava。工作目录是E：\ Inheritance 运行员工静态错误：此类没有接受String []的静态void main方法。

我把你的代码放在drjava-beta-20160913-225446（实际上是默认设置），编译并运行它，它运行正常（没有错误）。检查DrJava设置或获取不同版本的DrJava。

我有一个main方法，但是我得到静态错误：这个类没有静态void main方法接受String []
