Program Explanation

1. Get three inputs num1,num2 and num3 from user using scanner class

2. check whether num1 is greater than num2 and num1 is greater than num3 using if statement.

        if num1 is greater

            2a. print num1 using system.out.println,

        else

            2b. check whether num2 is greater than num1 using elseif statement.

                If num2 is greater

                    2b1. print num2 using printf statement,

                else

                    2b2. print num3 using system.out.println.
