what does static means 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: why we use static in java

In Java, static keyword is mainly used for memory management.
It can be used with variables, methods, blocks and nested classes.
It is a keyword which is used to share the same variable or method of a given
class. Basically, static is used for a constant variable or a method
that is same for every instance of a class

Example 3: static in java

static keyword is a non-access modifier. static keyword can be used with 
class level variable, block, method and inner class or nested class.

Example 4: static in java

The static keyword in Java is used for memory management mainly. We can apply static keyword with
variables, methods, blocks and nested classes. The static keyword belongs to the class 
  than an instance of the class.

The static can be:

Variable (also known as a class variable)
Method (also known as a class method)
Block
Nested class
