Java for-each loop

 Java for-each loop

Java provides an enhanced for loop to traverse the data structures like array or collection. In the for-each loop, we don't need to update the loop variable. The syntax to use the for-each loop in java is given below.

1. for(data_type var : array_name/collection_name){    
2. //statements    
3. }    

Consider the following example to understand the functioning of the for-each loop in Java.

ForEachTest.java

1. public class ForEachTest{    
2. public static void main(String[] args) {    
3. String[] names = {"Rahul","Nirmal","Siva","Deepak","Rani"};    
4. System.out.println("Printing the content of the array names:\n");    
5. for(String name:names) {    
6. System.out.println(name);    
7. }    
8. }    
9. }    

Output:

Printing the content of the array names:

Rahul

Nirmal

Siva

Deepak

Rani
