Question

Write a static method countEvens() that has four integer parameters, and returns the count of parameters where the value is an even number (i.e. evenly divisible by 2).

Answer 1

To write the static method countEvens(), we need to define four integer parameters. The method should then iterate over these parameters and count the ones that are even numbers (i.e. divisible by 2).

Step-by-step explanation:

To write the static method countEvens(), we need to define four integer parameters. The method should then iterate over these parameters and count the ones that are even numbers (i.e. divisible by 2). We can achieve this by using an if statement to check if each parameter is divisible by 2 using the modulo operator (%). If the remainder is 0, we increment a counter variable. Finally, we return the value of the counter as the result of the method.

Here's an example implementation in Java:

public static int countEvens(int num1, int num2, int num3, int num4) {
int count = 0;

if (num1 % 2 == 0) {
count++;
}

if (num2 % 2 == 0) {
count++;
}

if (num3 % 2 == 0) {
count++;
}

if (num4 % 2 == 0) {
count++;
}

return count;
}
