需要帮助解决静态方法 [英] Need help Solving static methods

问题描述

大家好：

我需要帮助请我还在学习Java ...

这是我的代码中我遇到问题的一部分。

问题出在public static void main（String [] args）{

方法main不能声明为static;静态方法只能在静态或顶级类型中声明。

这是部分我遇到问题的代码。

问题出在public static void main（String [] args）{

方法main不能声明为static;静态方法只能在静态或顶级类型中声明。鉴于缩进级别，在主要方法定义之前应该是其他代码。

谢谢Jos，我发现了这个错误。

现在我在线程中有一个异常main java.lang.NullPointerException

at company.Employee。< init>（Employee.java:141）

at company.Employee.main（Employee.java:250）


我认为它必须归功于我的arraylist。


第141行

没关系我解决了我做过的问题不需要那个陈述。

但是现在当我运行程序时，我得到了一个

异常的主题" main" java.lang.NullPointerException

at company.Employee.displayMatch（Employee.java:217）

at company.Employee.main（Employee.java:266)< br / >

谢谢

Hi everyone:
I need help Please I''m still learning Java...
Here is part of my code where I''m having problems.
Problem is at public static void main(String[] args) {
The method main cannot be declared static; static methods can only be declared in a static or top level type..

be some other code before your main method definition.

Thanks Jos, I found the mistake.
Now I have a Exception in thread "main" java.lang.NullPointerException
at company.Employee.<init>(Employee.java:141)
at company.Employee.main(Employee.java:250)

I think it has to due to my arraylist.

line 141 is

Never mind I solved that problem I did not need that statement.
But now when I run the program I get a
Exception in thread "main" java.lang.NullPointerException
at company.Employee.displayMatch(Employee.java:217)
at company.Employee.main(Employee.java:266)

thanks
