该程序允许用户输入贷款金额和贷款期限。
每月和总付款应以利率增加1/8显示。到目前为止,我已经足够正确地计算了一个数量,但我不明白如何显示所有结果。
我拍下了下面问题的说明:
import java.util.Scanner;
class ComputeLoan
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
//Enter number of years
System.out.print("Enter number of years as an integer: ");
int numberOfYears = input.nextInt();
//Enter loan amount
System.out.print("Enter Loan amount: ");
double loanAmount = input.nextDouble();
//Declare interest rate
double interestRate = 5.000;
//Obtain monthly interest rate
double monthlyInterestRate = interestRate / 1200;
//Calculate payment
double monthlyPayment = loanAmount * monthlyInterestRate / (1 - 1 / Math.pow(1 + monthlyInterestRate, numberOfYears * 12));
double totalPayment = monthlyPayment * numberOfYears * 12;
for (double intRate=5.000; intRate <8.000; intRate = intRate + .125);
{
double intRate=5.000;
System.out.println("The InterestRate is " + intRate);
System.out.println("The monthly payment is $" +
(int)(monthlyPayment * 100) / 100.0);
System.out.println("The total payment is $" +
(int)(totalPayment * 100) / 100.0);
}
//Display Results
}
}

你好试试像这样计算for循环
import java.util.Scanner;
class ComputeLoan
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
//Enter number of years
System.out.print("Enter number of years as an integer: ");
int numberOfYears = input.nextInt();
//Enter loan amount
System.out.print("Enter Loan amount: ");
double loanAmount = input.nextDouble();
for (double intRate=5.000; intRate <8.000; intRate = intRate + .125)
{
//Obtain monthly interest rate
double monthlyInterestRate = intRate / 1200;
//Calculate payment
double monthlyPayment = loanAmount * monthlyInterestRate / (1 - 1 / Math.pow(1 + monthlyInterestRate, numberOfYears * 12));
double totalPayment = monthlyPayment * numberOfYears * 12;
System.out.println("The InterestRate is " + intRate);
System.out.println("The monthly payment is $" +
(int)(monthlyPayment * 100) / 100.0);
System.out.println("The total payment is $" +
(int)(totalPayment * 100) / 100.0);
}
}
}

查看您链接到我们的图片,我猜测您正在尝试为每列提供相等的空间。 System.out.printf()
和String.format()
是您可能感兴趣的功能。
下面的代码将第一个十进制数转换为3个位置,第二个和第三个转换为2个位置。每列包含20个空格。
System.out.printf("%20s%20s%20s",
"Interest Rate", "Monthly Payment", "Total Payment");
System.out.printf(%20.3f%20.2f%20.2f,
intRate, monthlyPayment, totalPayment);
