java static meaning 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 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.

Example 3: static keyword in java

// example on static block in java.
public class StaticBlockExample
{
   // static variable
   static int a = 10;
   static int b;
   // static block
   static
   {
      System.out.println("Static block called.");
      b = a * 5;
   }
   public static void main(String[] args)
   {
      System.out.println("In main method");
      System.out.println("Value of a : " + a);
      System.out.println("Value of b : " + b);
   }
}

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: 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.

Example 6: 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();
   }
}
