Find the missing number in sorted array ?

>> In Java, we can find missing number using for loop.

logic: (sum of numbers in given array range)-(sum of numbers in given array)

public class findMissingNumber {
    public static void main(String[] args) {
    int numbers[] = { 1, 2, 3, 4, 6 };
    int sum = 0;
    // add numbers in given array
    for (int i = 0; i < numbers.length; i++) {
        sum = sum + numbers[i];
    }
    System.out.println("sum of numbers in given array=" + sum);

    int sum1 = 0;
    // add numbers till max range in given array
    for (int j = 1; j <= 6; j++) {
        sum1 = sum1 + j;
    }
    System.out.println("sum of numbers=" + sum1);

    System.out.println("Missing number=" + (sum1 - sum));
    }
}
