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
