Register for more A-Z Generally, final static members especially, variables (or static final of course, they can be used in either order without overlapping the meaning) are extensively used with interfaces in Java to define aprotocol behaviorfor the implementing class which implies that the class that implements (inherits) The static keyword in Java means that the variable is shared between all instances of that class as it belongs to the type, not the actual objects themselves. Static in Java roughly means that a variable is shared between all class instances (and class itself). It is initialized before everything else, and when you update it in one instance its reflected in all other instances. Your programs execution is as follows Generally, final static members especially, variables (or static final of course, they can be used in either order without overlapping the meaning) are extensively used with interfaces in Java to define a protocol behavior for the implementing class which implies that the class that implements (inherits) I suspect that static variables have a slightly different meaning in C to what they do in Java.

The static modifier marks a variable or a method as a class member Which means, the static element is shared across all instances of this class (all the objects that you create of this class). This means you can call a static method without creating any instance of the class by just using the name of the class e.g. Math.random() for creating random numbers in Java. Often utility methods which dont use the member variables of the class are declared static. This means that at the time the static block executes, the num field is not yet defined. The simple fix is moving the declaration above the block.
