Enhanced for - loop or for-each loop

-

 This feature is introduced in Java 5. It is a specially designed loop to retrieve elements of arrays and collections.

For eg: (1)int[ ] x= { 10, 20,30,40};

     To print elements of the above array:

Normal loop                                            

                for(int i=0; i<x.length; i++)

                 System.out.println(x[i]);

Enhanced for loop

                for(int x1 : x)

                System.out.println(x1);

(2) For 2-D arrays

Normal loop                                            

                for(int i=0; i<x.length; i++)

                {    for (int j=0; j<x[i].length; j++)

                        { System.out.println(x[i]);}

                }

            

Enhanced for loop

                for(int x1 : x)

              {    for( int x2: x1)

                    {  System.out.println(x2);}

                }

         The enhanced for loop executes in sequence.ie the counter is always increased by one , whereas in normal for loop you can change the steps as per your wish. eg: doing something like i= i+2;

Arrays

-
           Arrays are indexed collection of homogeneous data elements.The main advantage of arrays is we can represent huge number of values by using single variable so that readability of the code will be improved. But the main disadvantage is ,it is fixed in size.ie, once we creates an array there is no chance of increasing or decreasing the size based on our requirement.And knowing the size of the array in advance may not be possible always. ARRAY DECLARATION int[ ] x; OR int [ ]x; OR int x[ ]; Size of the array is specified only at creation not during declaration. ARRAY CREATION Every array in java is an object.Hence we can create arrays using 'new' operator. int[ ] a = new int[3]; 'a' is the reference variable ARRAY INITIALIZATION int[ ] x = new int[3]; x[0]=1; x[1]=2; x[2]=3; ARRAY DECLARATION,CREATION AND INITIALIZATION IN A SINGLE LINE int[ ] x= {10,20,30}; char[ ] ch= {'a','e','i','o','u'}; String[ ] s= {"A",...

Constructors

-
 Once we create objects, compulsorily we have to initialize it. Otherwise the objects are not in a position to respond properly. Constructors are specially designed methods for initializing instance variables/objects. After the creation of objects immediately the constructor will be executed and initialization is performed. Rules for constructors Name of the constructor and the name of the class must be same. There is no return type for constructors, not even void. ( If return type is given, it is treated as a normal method. ie, you can give the name of the class as the name of a normal method,but strictly it is not recommended.) The access modifiers applicable for constructors are public, <default>, protected and private. Example:                          class test               {          String name;          ...
