5 simple ways to print java array

You can print a Java array in so many different ways depending upon your Java version. I have collated 5 easy and simple ways to print arrays in Java.

import java.util.Arrays;

public class Simple5WaysToPrintJavaArray {

	public static void main(String[] args) {
	    int[] intArray = new int[] {1, 2, 3, 4, 5};
	    String[] strArray = new String[] {"John", "Mary", "Bob", "Don", "Chris"};

	    //Method 1 - This will be useful to print using prior versions of Java 8
	    System.out.println(Arrays.toString(intArray));
	    System.out.println(Arrays.toString(strArray));

	    // Method 2 - In Java 8 we have lambda expressions
	    Arrays.stream(intArray).forEach(System.out::print);
	    System.out.println("");
	    Arrays.stream(strArray).forEach(System.out::print);
	    System.out.println("");
	    
	    //Method 3 - using a for loop - using one loop as the lengths are same
	   for (int i = 0; i < intArray.length; i++) {
		   System.out.print(intArray[i] + ", ");
		   System.out.print(strArray[i] + ", ");
		}
	   System.out.println("");
	   
	   //Method 4 - using  Arrays.asList - only works with String as int is primitive
	   System.out.println(Arrays.asList(strArray));
	   
	   
	   //Method5 - using extended for loop from Java 5
	   for(int i:intArray){
		   System.out.print(i+ ", ");
	   }
	   System.out.println("");
	   for (String str : strArray) {
           System.out.print(str+ ", ");
       }
	   
	}

}

Output: [1, 2, 3, 4, 5] [John, Mary, Bob, Don, Chris] 12345 JohnMaryBobDonChris 1, John, 2, Mary, 3, Bob, 4, Don, 5, Chris, [John, Mary, Bob, Don, Chris] 1, 2, 3, 4, 5, John, Mary, Bob, Don, Chris,
