Nested while loop in java

-
Placing one while loop with in the body of another while is called Nested while loop in java programm.


CODE

 
public class NestedWhileExample
{
    public static void main(String arg[])
    {
        int outer = 1;
        while(outer < 3)
        {
            int inner = 5; 
            while(inner < 8)
            {
                System.out.println(outer + "  " + inner);
                inner++;
            }
            outer++;
        }
    
    }
}



Output :


1 5


1 6


1 7


2 5


2 6


2 7







DESCRIPTION

Here outer loop is executed for values going from 1 till less than 3 i.e. 1 and 2. Similarly inner loop is executed from 5 till less than 8 i.e. 5, 6 and 7. So when outer is 1, inner will become 5, 6, and 7 and when outer is 2, then also inner will become 5, 6, and 7.

Java Design pattern

 Singleton Design pattern :-  it's Creational Design Pattern as we need to have only one instance of our class for Ex:- Logger,DBConnector. SingleObject class have its constructor as private and have a static instance of itself. Code:-                        public class Singleton { 	private static Singleton object;  	private Singleton() { 	}  	public static synchronized Singleton getInstance() { 		if (object == null) 			object = new Singleton(); 		return object; 	} }              Eager Initialization :-  public class Singleton { 	 private static Singleton object = new Singleton(); 	 private Singleton() { 	 } 	 public static Singleton getInstance() { 		 return object; 	 } } Double checked Locking :-  public class Singleton { 	 private static volatile Singleton obj = null; 	 private Singleton() { 	 } 	 public static Singleton getInstance() { 		 if (obj == null) { 			 synchronized (Singleton.class) { 				 if (obj == null) 					 obj = new Singleton(); 			 } 		 } 		...
