java static variable 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: static variables 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.

Example 3: what is static methods and variables

The methods or variables defined as static are shared among all the objects 
of the class. The static is the part of the class and not of the object. 
The static variables are stored in the class area, and we do not need 
to create the object to access such variables. 
Therefore, static is used in the case, where we need to define 
variables or methods which are common to all the objects of the class.
For example, In the class simulating the collection of the students in 
a college, the nameof the college is the common attribute to all the students.
Therefore, the college name will be defined asstatic

Example 4: 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 5: Static method in java

We can declare a method as static by adding keyword “static” before method name.
Let’s see example on static method in java.

public class StaticMethodExample
{
   static void print()
   {
      System.out.println("in static method.");
   }
   public static void main(String[] args)
   {
      StaticMethodExample.print();
   }
}
