帮忙用textpad写一串JAVA编码，程序要求在下方。答的好的加50分
1. Write a program that reads in investment amount, annual interest rate, and number
of years, and displays the future investment value using the following formula:
futureInvestmentValue = investmentAmount(1+monthlyInterestRate)numberOfYears*12
Hint: Use the Math.pow(a, b) method to compute a raised to the power of b.

Answer 1

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
/*
* 2.9 (Calculatingthe future investment value) Write a program that reads ininvestment amount,
* annual interestrate, and number of years, and display the future investment valueusing the
* followingformula:
futureInvestmentValue =
investmentAmount x(1 + monthlyInterestRate)numberofYears*12
For example, if youentered amount 1000, annual interest rate 3.25%, and number ofyears 1, the future investment value is 1032.98.
Hint:
Use the Math.pow (a,b) method to compute a raised to the power of b.
