Java: Test that a given array of integers of length 2 contains a 4 or a 7
Java Basic: Exercise-78 with Solution
Write a Java program to test that a given array of integers of length 2 contains a 4 or a 7.
Sample Solution:
Java Code:
import java.util.Arrays;
public class Exercise78 {
public static void main(String[] args) {
// Define an integer array, array_nums
int[] array_nums = {5, 7};
// Print the elements of the original array
System.out.println("Original Array: " + Arrays.toString(array_nums));
// Check if the first element of the array is 4 or 7 and print the result
if (array_nums[0] == 4 || array_nums[0] == 7) {
System.out.println("True");
} else {
// If the first element is not 4 or 7, check the second element and print the result
System.out.println(array_nums[1] == 4 || array_nums[1] == 7);
}
}
}
Sample Output:
Original Array: [5, 7] true
