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

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+ " ");
      }
   }
}

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