10 as First or Last in Array

Write a Java program to test if 10 appears as the first or last element of an array of integers. The array length must be broader than or equal to 2.

Sample Solution:

Java Code:

import java.lang.*;

public class Exercise74 {
    public static void main(String[] args) {
        // Define an integer array
        int[] num_array = {10, -20, 0, 30, 40, 60, 10};
        
        // Check if the first or last element of the array is equal to 10
        boolean result = (num_array[0] == 10 || num_array[num_array.length - 1] == 10);

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

Sample Output:

true
