First and Last Element Same

Write a Java program to test if the first and last elements of an array of integers are the same. The array length must be broader than or equal to 2.

Sample Solution:

Java Code:

import java.lang.*;

public class Exercise75 {
    public static void main(String[] args) {
        // Define an integer array
        int[] num_array = {50, -20, 0, 30, 40, 60, 10};
        
        // Check if the array has at least 2 elements and if the first and last elements are equal
        boolean result = (num_array.length >= 2 && num_array[0] == num_array[num_array.length - 1]);

        // Print the result
        System.out.println(result);
    }
}

Sample Output:

false
