Static Members in Java

The class level members which have static keyword in their definition are called static members. All static members are identified at the time of class loading by default by JVM in method area. Only variables get memory location, methods will not have separate memory location like variables. They are just identified and can be accessed directly without object creation.

Types of Static Members

Java supports four types of static members

➯ Static Variables

➯ Static Blocks

➯ Static Methods

➯ Main Method

Static Variable

JVM executes static variables i.e provides memory location, at the time of class loading. Example:

    
    static int a=10; 
    
    //here 'a' represents a variable with static value.
    
     

Static variable get life as soon as class is loaded into JVM and is available till class is removed from JVM (or) JVM Is shutdown.

Static Method

JVM will not execute static methods by itself. They are executed only if they are called explicitly by developer

➯ either from main method, or

➯ from static variable as its assignment statement or

➯ from static block.

Static block

Static block is a class level nameless block contains only static keyword in its prototype.


    
    class Example
{
    static
    {
    --------------
    --------------
    --------------
    }
}


Static block is always executed before main method. One can define more than one static block in a class
