[duplicate] up vote 117 down vote favorite 50 This question already has an answer here: Non-static variable cannot be referenced from a static context 10 answers The very common beginner mistake is when you try to use a class property "statically" without making an instance of that class. It leaves you with the mentioned cannot be referenced from a static context java error message. You can either make the non static method static or make an instance of that class to use its properties. Why? I am not asking for solutions. I would be grateful to know what's the reason behind it. The very core reason! private java.util.List

[duplicate] 13 answers In writing a BookStoreApplication which uses Book, Tape, and CD classes to create objects. Although unfinished, the application class should create new BookStoreItems, which are Book, Tape, and CD. They inherit from the BookStoreItems class.

you resolve the Java error "Non-static method cannot be referenced from a static context"?UpdateCancelAnswer Wiki4 Answers Satnam Singh, I have decades of functional programming experience esp. in Haskell.Written 39w agoHere is an example of https://www.quora.com/How-do-you-resolve-the-Java-error-Non-static-method-cannot-be-referenced-from-a-static-context the situation you describe:public class Points { int x; int y; public static void zeroPoint() { setPoint(0, 0); } public void setPoint (int xpos, int ypos) { x = xpos; y = ypos; } } This will result in a compile time error because it does not make sense for zeroPoint to contain a call to setPoint. The zeroPoint static method does not know which point is cannot be to be set.Classes contain two kinds of methods: static methods and instance methods. The static methods can not call the instance methods directly. Instance methods effectively have an additional implicit parameter that is a reference to an object that is an instance of the class (that is what this corresponds to). Static methods don't: they are much more like regular functions or procedures in non-OO languages. cannot be referenced If you find yourself calling an instance method from a static method (in the same class or elsewhere) then something has gone wrong with the structure of your code. The static method has no idea what object the instance method is being applied to. Of course, you could inside a static method create an instance of a class, or pass one in through parameters, and then make calls on that object. But I sense that is not what is going on here.4k Views · View UpvotesRelated QuestionsMore Answers BelowWhy can't a non-static method be referenced from a static context?In Java, a static method can only call other static methods.
