In above example, we have a non-static method named calculation. From the main method (static method), I'm trying to access that non-static method and to do this I need to create the instance of the class inside the main method (static method) because a static method only accesses the...

In Java, methods can be static when belonging to a class, or non-static when an object of the class. Compare static and non-static methods through...
bug记录|NON-STATIC METHOD CANNOT BE REFERENCED FROM A STATIC CONTEXT 问题: 原因: 静态方法无法调用自己定义的非静态方法 解决方案: 1.改变非静态方法为静态方法,在add方法中的void前加static 2.可在main主方法里实例化非静态方法的对象 以下为例:
错误信息“Non-static method cannot be referenced from a static context”是因为Lambda表达式试图访问一个非静态的方法,而这个方法需要一个对象实例才能被调用。解决这个问题的方法有两种: 将方法声明为静态:如果可能的话,最简单的解决方案是将非静态方法声明为静态。这样,你就可以在Lambda表达式中直接调用它。
