Hi,

The static variable is declared by using static keyword. Following is an example of static declaration:

static int i=10;

The variable declared with static keyword is called class variable. This variable is shared by all the instances of the class. The static variable can be accessed without creating the instance of the class.

This variable is created statically and same variable is accessed by all instance of the class.

Check the tutorial static Java Keyword.

Thanks
