Java: 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 another array.
Sample Solution:
Java Code:
import java.util.Arrays;
public class Exercise81 {
public static void main(String[] args) {
// Define an integer array, array_nums
int[] array_nums = {20, 30, 40};
// Print the elements of the original array
System.out.println("Original Array: " + Arrays.toString(array_nums));
// Store the value of the first element in the variable x
int x = array_nums[0];
// Swap the first and last elements of the array
array_nums[0] = array_nums[array_nums.length - 1];
array_nums[array_nums.length - 1] = x;
// Print the new array after swapping the first and last elements
System.out.println("New array after swapping 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]
Flowchart:

Java Code Editor:
Previous: Write a Java program to get the larger value between first and last element of an array (length 3) of integers.
Next: Write a Java program to find the largest element between first, last, and middle values from an array of integers .
