static keyword in java short explanation

 Static variable-static method and static block

static keyword 

The static keyword in Java is mainly used for memory management. When a member is declared static, it can be accessed directly.To create a static member, the static keyword is used before its declaration.Block, variable, method and classes can use static keyword.

java buzzwords explanation

static variable and static method

in java have different types of variables are available

local,instance and static variable

In a class global variables are declared using the static keyword

Definition of object —>An object is programming entity and class is collection of object

Every class will be having variables and methods

If the variable declare as a static these static variable can be access into two ways

1 directly access—>If our program is in a single class You can directly access the variable

2 with the help of class name—->If your program is in multiple classes You can access the variable with the help of class name

similarly the static method also we can do directly access

if the program in single class

If there is more than one class, you can access

the static method by giving the class name

static block

Static blocks can be written in static keyword and curly braces.

whatever content written in static block can be executed by

default without any explicit call and if there is any reference

to the particular class

sample program

class StaticExample

{

    static int num=100;

    static void disply()

    {

        System.out.println("this is static method"); 

    }

    static

    {

        System.out.println("this is static block");

    }

    public static void main(String args[])

    {

        System.out.println(num);

        disply();

    }

} 

In this program static block is printed first and 

then variable num and display functions are printed respectively

output

this is static block

100

this is static method
