public − This is the access specifier that states that the method can be accesses publically. static − Here, the object is not required to access static members. void − This states that the method doesn't return any value.

Final static variable in Java. ... Declaring variables only as static can lead to change in their values by one or more instances of a class in which it is declared. Declaring them as static final will help you to create a CONSTANT. Only one copy of variable exists which can't be reinitialize.

Static variables reduce the amount of memory used by a program. Static variables are shared among all instances of a class. Non static variables are specific to that instance of a class. ... Non static variable is like a local variable and they can be accessed through only instance of a class.

A static variable is a class variable. A single copy of the static variable is created for all instances of the class. It can be directly accessed in a static method. An abstract class in Java is a class that cannot be instantiated.

int is a datatype for a variable storing integer values. static int is a variable storing integer values which is declared static. ... Every time the function gets called, i gets initialized, its value gets incremented to 1 and gets destroyed when the function ends. Now lets see the same example with static int.

static means that the method is associated with the class, not a specific instance (object) of that class. ... void means that the method has no return value. If the method returned an int you would write int instead of void .

If you only want to use a method without creating an instance of the class, static methods are the way to go. However, static methods can only access static variables, also called class variables whereas nonstatic instance methods can access static and nonstatic variables.

Static variables: means that they will die with the program itself, this means that the memory will be allocated & never will be released implicitly. Global: these variables can be accessed from anywhere. Local: these variables can be accessed inside their scopes only.

int is a datatype for a variable storing integer values. static int is a variable storing integer values which is declared static. ... But if we declare an int variable in a function also as static, then that variable will not get destroyed as the function ends and will not get destroyed until the program ends.

Void simply means nothing. It doesn't take any parameters nor it returns anything. Return is use to give command back to the calling function and it returns value to Calling function.

public means you can access it anywhere while private means you can only access it inside its own class. Just to note all private, protected or public modifier are not applicable to local variables in Java.

Void functions are created and used just like value-returning functions except they do not return a value after the function executes. In lieu of a data type, void functions use the keyword "void." A void function performs a task, and then control returns back to the caller--but, it does not return a value.

A null pointer points has the value NULL which is typically 0, but in any case a memory location which is invalid to dereference. A void pointer points at data of type void. The word "void" is not an indication that the data referenced by the pointer is invalid or that the pointer has been nullified.
