Static Method A method in Java is static when it is preceded by the keyword “static” Some points that you need to remember about the static method include: A static method belongs to the class as against other non-static methods that are invoked using the instance of a class To invoke a static method, you don’t need a class object
- In laymans terms, what does static mean in Java?
The static keyword can be used in several different ways in Java and in almost all cases it is a modifier which means the thing it is modifying is usable without an enclosing object instance Java is an object oriented language and by default most code that you write requires an instance of the object to be used
- java - Difference between Static and final? - Stack Overflow
A static method can be accessed directly by the class name and doesn’t need any object Syntax: Class methodName() A static method cannot refer to this or super keywords in anyway Static class Java also has "static nested classes" A static nested class is just one which doesn't implicitly have a reference to an instance of the outer class
- How does the static keyword work in Java? - Stack Overflow

- java - What is the actual memory place for static variables? - Stack . . .
In fact, static frames (i e the frames that hold the static variables) ARE allocated from the heap And they don't necessarily exist for the duration of a program's execution For instance, static frames for classes that are dynamically loaded can be garbage collected if the parent classloader, all classes and all instances becomes unreachable
- In Java, is there any disadvantage to static methods on a class?
+1; some folks say that static is NOT object-oriented concept (for the reasons you are talking about) And in Java there is almost 0 performance boost for static methods vs member methods (look into compiled byte code -- it is a matter of pushing an object reference to stack -- must be several picoseconds or so :) Furthermore, if you use reflection with static methods, you still need to pass
- java - What does the Static keyword do? - Stack Overflow
static as a keyword in Java means that the field is a Class field not a instance field These are supposed to be used for fields that are used between instances of the class and don't have any meaning for a given instance In your case the xPos and yPos are for each instance of the class Take a look at this static tutorial
