Question

帮忙用textpad写一串JAVA编码，程序要求在下方。答的好的加50分

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.

public class InvestmenntValue{

public static void main(String[] args)throwsIOException {

double investmentAmount =0.0;

double yearlyInterestRate =0.0;

double monthlyInterest =0.0;

int years = 0;

System.out.println("Enter investment amount:" );

investmentAmount =Double.parseDouble(my_Buffer.readLine());

System.out.println("Enter annualinterest rate : " );

yearlyInterestRate =Double.parseDouble(my_Buffer.readLine());

System.out.println("Enter years: ");

years =Integer.parseInt(my_Buffer.readLine());

yearlyInterestRate /=100.0;

monthlyInterest = yearlyInterestRate/ 12.0;

years *= 12;

temp = investmentAmount * (1 +monthlyInterest);

futureInvestmentValue =Math.pow(temp, years);

System.out.println("Answer = "+String.valueOf(futureInvestmentValue));
