Java For each Loop

The basic for loop was extended in Java 5 to make iteration over arrays and other collections more easy. This newer for statement is called the enhanced for or for-each. The for-each loop is used to access each successive value in a collection of values. The main usage of for each is iterating over collection classes or arrays. Here is the syntax to use for each loop:

for (data_type item: iterable_collection or array) {
       // do something to item

Here is an example for for each loop:

package com.java2novice.loops;

import java.util.ArrayList;
import java.util.List;

public class SimpleForEachEx {

	public static void main(String a[]){
		List<String> al = new ArrayList<String>();
		al.add("for each");
		al.add("java 1.5");
		 * during each iteration, the object in the sequence 
		 * will be assigned to string reference str.
		for(String str:al){

for each

Knowledge Centre
Purpose of garbage collection
The garbage collection process is to identify the objects which are no longer referenced or needed by a program so that their resources can be reclaimed and reused. These identified objects will be discarded.
Famous Quotations
It is easier to fight for one’s principles than to live up to them.
