Answer 1

Answer:

public static int square(int num){

       return num*num;

   }

Explanation:

Using the Java Programming Language, we declare a function named square as stated in the question, the return type of the function is stated as integer. And the the parameter it receives is an integer number called num.

To get the square of the number we use the expression num*num, and return the the squared value. When the function is called, it will receive one argument (an integer value), it will calculate the square and return it.
