所以我是一個初學者,你可以告訴我,我目前正在嘗試理解參數,並想知道我是否正確地做了這個。該程序的工作原理,但我不想讓它格式錯誤,或者我沒有理由使用它們,因爲參數(?)不會改變。我們目前正在研究參數,所以我想我會試一試,並嘗試將其納入本作業。我使用了正確的參數嗎?
import java.util.Scanner;
public class Investments
{
public static void main(String []args)
{
double investment,interestRate, futureValue;
Scanner keyboard = new Scanner(System.in);
System.out.println("What is the investment amount?");
investment = keyboard.nextDouble();
System.out.println("What is the interest rate?");
interestRate=keyboard.nextDouble();
futureValue = investment * (Math.pow(1+interestRate, 5));
futureValue = investments(futureValue);
System.out.println("Your investment afer 5 years:" + futureValue);
futureValue = investment * (Math.pow(1+interestRate, 10));
futureValue = investments(futureValue);
System.out.println("Your investment after 10 years:" + futureValue);
futureValue = investment * (Math.pow(1+interestRate, 20));
futureValue = investments(futureValue);
System.out.println("Your investment after 20 years:" + futureValue);
}
public static double investments (double futureValue)
{
double result;
result = Math.round(futureValue * 100);
result = result/100;
return result;
}
}
你試過編譯並運行它,那是要檢查的最佳途徑,如果你的代碼工作:-) ?對我來說似乎沒問題。 – ctst
感謝讚賞反饋。我確實運行它,它的工作原理!我只需要知道我是否做得正確 –
