Java For Each Loop

For Each Loop

  • For each loop is an enhanced version of for loop.
  • It travels each element of the data structure one by one.
  • Note that you can not skip any element in for loop and it is also not possible to traverse elements in reverse order with the help of for each loop.
  • It increases the readability of the code.
  • If you just want to simply traverse an array from start to end then it is recommended to use for each loop.
  • Syntax :
/* for (int element:Arr) {
Sout(element); //Prints all the elements
} */

Example :

class CWH_forEachLoop{  
  public static void main(String args[]){  
   //declaring an array  
   int arr[]={1,2,3,3,4,5};  
   //traversing the array with for-each loop  
   for(int i:arr){  
     System.out.println(i);  
   }  
 }   
}  

Output :

1
2
3
4
5

Example

package com.company;

public class cwh_27_arrays {
    public static void main(String[] args) {

        /*
        float [] marks = {98.5f, 45.5f, 79.5f, 99.5f, 80.5f};
        String [] students ={"Harry", "Rohan", "Shubham", "Lovish"};
        System.out.println(students.length);
        System.out.println(students[2]);
        */

        int [] marks = {98, 45, 79, 99, 80};
        // System.out.println(marks.length);

        // Displaying the Array (Naive way)
        System.out.println("Printing using Naive way");
        System.out.println(marks[0]);
        System.out.println(marks[1]);
        System.out.println(marks[2]);
        System.out.println(marks[3]);
        System.out.println(marks[4]);

        // Displaying the Array (for loop)
        System.out.println("Printing using for loop");
        for(int i=0;i<marks.length;i++){
            System.out.println(marks[i]);
        }
