Java Exercises: Swap the first and last elements of an array and create a new array

Java Basic: Exercise-81 with Solution

Write a Java program to swap the first and last elements of an array (length must be at least 1) and create a new array.

Sample Solution:

Java Code:

import java.util.Arrays; 
 public class Exercise81 {
 public static void main(String[] args)
 {
    int[] array_nums = {20, 30, 40};
	System.out.println("Original Array: "+Arrays.toString(array_nums)); 
	int x = array_nums[0];
	array_nums[0] = array_nums[array_nums.length-1];
	array_nums[array_nums.length-1] = x;
	System.out.println("New array after swaping the first and last elements: "+Arrays.toString(array_nums));  
 }
}

Sample Output:

Original Array: [20, 30, 40]                                           
New array after swaping the first and last elements: [40, 30, 20]
