This class implements a simple program that will compute the amount of interest that is earned on an investment over a period of one year. The initial amount of the investment and the interest rate are input by the user. The value of the investment at the end of the year is output. The rate must be input as a decimal, not a percentage (for example, 0.05 rather than 5). with user input
