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

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

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+ " ");
      }
   }
}

The above code sample will produce the following result.

Display an array using for loop
1 2 3 4 
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 {  
   public static void main(String args[]) {  
      ArrayList<String> list = new ArrayList<String>();  
      list.add("Tutorials");  
      list.add("Point");  
      list.add("India PVT Limited");
      for(String s:list) { 
         System.out.println(s);  
      }
