Problem Description

How to use for and foreach loops to display elements of an array.

Solution

This example displays an integer array using for loop & foreach loops.

public class Main {
   public static void main(String[] args) {
      int[] intary = { 1,2,3,4};
      forDisplay(intary);
      foreachDisplay(intary);
   }
   public static void forDisplay(int[] a) {  
      System.out.println("Display an array using for loop");
      for (int i = 0; i < a.length; i++) {
         System.out.print(a[i] + " ");
      }
      System.out.println();
   }
   public static void foreachDisplay(int[] data) {
      System.out.println("Display an array using for each loop");
      for (int a  : data) {
         System.out.print(a+ " ");
      }
   }
}

Result

The above code sample will produce the following result.

Display an array using for loop

Display an array using for each loop
1 2 3 4 

The following is an another sample example of Foreach

import java.util.*;  

public class HelloWorld {

      list.add("Tutorials");  
      list.add("Point");  
      list.add("India PVT Limited");
      for(String s:list) { 
         System.out.println(s);  
      }
