when do you use static in java code example

Example 1: 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);  
  }  
}

Example 2: java what is static

In the Java programming language, the keyword static indicates that the particular member belongs to a type itself,
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.
