For-each loop (Advanced or Enhanced For loop):

 

For-each loop (Advanced or Enhanced For loop):

The for-each loop introduced in Java5. It is mainly used to traverse array or collection elements. The advantage of for-each loop is that it eliminates the possibility of bugs and makes the code more readable.

Advantage of for-each loop:

• It makes the code more readable.
• It elimnates the possibility of programming errors.

Syntax of for-each loop:

1. for(data_type variable : array | collection){}  

---

Simple Example of for-each loop for traversing the array elements:

1.     
2. class ForEachExample1{  
3.   public static void main(String args[]){  
4.    int arr[]={12,13,14,44};  
5.   
6.    for(int i:arr){  
7.      System.out.println(i);  
8.    }  
9.   
10.  }   
11. }  
12.       

Test it Now

Output:12
       13
       14
       44

Simple Example of for-each loop for traversing the collection elements:

1. import java.util.*;  
2. class ForEachExample2{  
3.   public static void main(String args[]){  
4.    ArrayList<String> list=new ArrayList<String>();  
5.    list.add("vimal");  
6.    list.add("sonoo");  
7.    list.add("ratan");  
8.   
9.    for(String s:list){  
10.      System.out.println(s);  
11.    }  
12.   
13.  }   
14. }  
15.       

Test it Now

Output:vimal
       sonoo
       ratan
