Question 277
Square a Number
Square a Number
Create a class named MathUtil with a public static method Square that takes one integer parameter n and returns n multiplied by itself. The method should not print anything on its own; it just returns the squared value so that the caller can use it. For example, squaring 6 gives 36.
Expected Output:
36= newline. The output ends with a newline — print one after the last line.
