What is the reason behind “non-static method cannot be referenced from a static context”?

Hi,

To resolve this error, you either need to make someMethod() static or create an instance of the class and then call someMethod() on that instance.

The reason behind the error is that you’re trying to call a non-static method (someMethod()) from a static context (main() method) without creating an instance of the class. In Java, non-static methods belong to instances of a class, so they need to be called on an object of that class. Static methods, on the other hand, belong to the class itself and can be called without an instance.

Since someMethod() is not static, it needs to be called on an object. In your main() method, you’re trying to call someMethod() directly, which is incorrect. To fix this, you either need to make someMethod() static or create an instance of the class and then call someMethod() on that instance.

Another approach to consider is calling a method directly after instantiating the class using its constructor:

Object instance = new Constructor().methodCall();

This method is useful when you only need to use a method of an instantiable class once within a specific scope. However, if you plan to call multiple methods from an instantiable class within the same scope, it’s better to create a reference instance of the class.
