Foreach Loop in Java

It is similar to for loop used to retrieve elements of collection objects (until the last element)

Syntax

for(datatype variable:collection-object)
{
.....
.....
}

The above looping statement executed repeatedly several number of time until the elements are available in the collection object, the loop will be terminated if no elements found.

Note: foreach loop always traversing in forward direction.

Example of for...each Loop

import java.util.*;

class ForeachDemo
{
public static void main(String args[])
{  

ArrayList<Integer> al=new ArrayList<Integer>();  // creating arraylist
al.add(10);
al.add(20);
al.add(30);

for(int i : al)
{
System.out.println(i);  
}
}  
}  

Output

10
20
30
