The use of enhanced for loop enables us to loop through a collection member without knowing the size or explicitly iterating elements one by one . This feature is introduced with the Java SE platform in version 5.0.

Have a look how it simplifies programming.

Old form of looping.

for (int i=0; i <  nameArray.length; i++)
    {
       System.out.println("Name: " + array[i]);
    }

With Java SE 5.0. an enhanced looping would be like

for (String name : nameArray)
 {
    System.out.println("Name: " + name);
  }

where nameArray is an array of Strings
