Java Enhanced For Loop Example

Java Enhanced For Loop Example :

Enhanced For Loop is a more easy way and convenient way to iterate the elements from the collections or Arrays.

I am giving very basic Enhanced For Loop Example below.

The below code is very straight forward how you iterate the elements over the collections/arrays by using
Enhanced For Loop.

Enhanced For Loop Example Code 

import java.util.ArrayList;
//Java Enhanced for Loop Example
public class EnhancedForLoopExample {
    public static void main(String[] args) {
        String[] array = new String[] { "v1", "v2", "v3" };
        //Normal for loop iterate elements from the Array
        for (int i = 0; i < array.length; i++) {
            System.out.println("Normal For Loop : " + array[i]);
        }
        //Enhanced for Loop iterate elements from the Array
        for (String value : array) {
            System.out.println("Enhanced For Loop : " + value);
        }
        //Using generics storing the elements into the ArrayList
        ArrayList<String> aList = new ArrayList<String>();
        aList.add("v-1");
        aList.add("v-2");
        aList.add("v-3");
        //Normal for loop iterate elements from the ArrayList
        for (int i = 0; i < aList.size(); i++) {
            System.out.println("Normal For Loop : " + aList.get(i));
        }
        //Enhanced for Loop iterate elements from the ArrayList
        for (String value : aList) {
            System.out.println("Enhanced For Loop : " + value);
        }
    }
}

Output of the Program :


Normal For Loop : v1
Normal For Loop : v2
Normal For Loop : v3

Enhanced For Loop : v1
Enhanced For Loop : v2
Enhanced For Loop : v3

Normal For Loop : v-1
Normal For Loop : v-2
Normal For Loop : v-3

Enhanced For Loop : v-1
Enhanced For Loop : v-2
Enhanced For Loop : v-3
