what is static keyword in java
Static keyword is used a lot in java.
Static means, you
can access those static variables
without creating an object,
just by using a class name.
This means that only one instance of
that static member is created which
is shared across all instances of the class.
Basically we use static keyword when
all members share same instance.static in java
//Java Program to get the cube of a given number using the static method
using static before a method or variable we can access it by not creating a
instance of it.in the program we directly used student.cube(5)
class Calculate{
static int cube(int x){
return x*x*x;
}
public static void main(String args[]){
int result=Calculate.cube(5);
System.out.println(result);
}

rather than to an instance of that type.
This means that only one instance of that static member is created which is shared across all instances of the class.static in java

empID = ID;
empName = name;

{
public static void main(String[] args)
{
EmployeeDetails obj1 = new EmployeeDetails(230, "Virat");
