How to write an Financial equation in Java?
问题
我目前正在一个项目中工作，该项目涉及创建一个类似金融计算器的程序。然而，我目前遇到了一些问题，希望能从社区的人那里获得一些意见或获取一些知识。目前我正在使用Java Gradle和应用程序窗口，并且正在实际编写我的代码。然而，我在如何编写方程式方面遇到了问题，不确定是否应该在if循环中循环方程式，还是创建不同的类，以便一个类文件中不会有太多循环。在这一点上，我还想指出，我也在项目中使用Eclipse应用程序。
我目前正在编写的方程式是一个单一现金流，即FV = PV(1+i)^n，我不知道是否应该这样编写，或者我是否只是在过度思考方程式，实际方程式可能与所示方程式完全不同。如果是这样的话，我们是否需要对n开方？如果是的话，如何进行呢？
我感觉我可能过度思考了我的项目，无法看到眼前的问题。因此，请传授你的智慧给我。另外，有没有金融应用程序可以通过GitHub导入或安装，而不是使用npm？如果有任何链接，你们认为会有帮助的，请在下面友好地提供链接。因为我已经多次重新编写了我的代码，感觉一无所获。谢谢。
以下是不在Gradle应用程序窗口中的代码部分。
package Finance.Calculator.Project;
import static java.lang.Math.*;
import java.text.*;
import java.io.*;
public class SimpleFinanceCalc {
public double FutureValue;
public double PresentValue;
public double NumYears;
public double NumComYear;
public double Interest;
public double Growth;
public double CashFlow;
public String Operator;
public SimpleFinanceCalc(double FutureValue, double PresentValue, double NumYears, double NumComYear, double Interest, double Growth, double CashFlow, String Operator) {
this.FutureValue = FutureValue;
this.PresentValue = PresentValue;
this.NumYears = NumYears;
this.NumComYear = NumComYear;
this.Interest = Interest;
this.Growth = Growth;
this.CashFlow = CashFlow;
}
public Double Calculate() {
if (this.Operator.equals("Single Cash Flow")) {
return PresentValue * (1 + Interest) * Math.sqrt(NumYears);
}
}
}

I am currently working on a project which includes creating a program that runs similar to a financial calculator. However I am currently in a fix and would like to get some opinion or gain some knowledge form people within this community. Currently I am using Java gradle and application window and is in the process of actually writing my code. However I am in a fix on how to write the equations and if I should loop the equations in if loops or create different classes so there is not so many loops in one class file. On that note I would also like to note that I an using the Eclipse application for the project too.
The equation I am writing currently is a single cash flow which is FV = PV(1+i)^n and I don't know if I should or am able to write it like this or if I am just over thinking on equation and its totally different from the equation shown. If it is would we need to root the n and if so, how?
I feel like I am over thinking my project and can't see pass what is in front of me. So please past me your wisdom. On another note. Is there a financial application we can or would be able to import or install using github that is not a npm? Also if there is any links that you guy think would help please so kindly link it down below please. For I have restarted my code several times already and feel like I am not getting anywhere. Thank you.
Here is a portion of my code that is not within the gradle application window.
package Finance.Calculator.Project;
import static java.lang.Math.*;
import java.text.*;
import java.io.*;
public class SimpleFinanceCalc {
public double FutureValue;
public double PresentValue;
public double NumYears;
public double NumComYear;
public double Interest;
public double Growth;
public double CashFlow;
public String Operator;
public SimpleFinanceCalc (double FutureValue, double PresentValue, double NumYears, double NumComYear, double Interest, double Growth, double CashFlow, String Operator){
this.FutureValue = FutureValue;
this.PresentValue = PresentValue;
this.NumYears = NumYears;
this.NumComYear = NumComYear;
this.Interest = Interest;
this.Growth = Growth;
this.CashFlow = CashFlow;
}
public Double Calculate() {
if(this.Operator.equals("Single Cash Flow")) {
return PresentValue * (1 + Interest) Math.sqrt(NumYears)
}
}
}
