创建决策陈述？

Question

该计划应该输出投资的增长收益率。投资金额，持续时间和基本费率将作为用户对程序的输入提供。根据下表每年应用增长率：

到目前为止我所拥有的只是用户输入代码，

import javax.swing.JOptionPane;

public class InvestGrowth {
    public static void main(String[] args) {
        double investment, duration, baserate, growth;

        investment = Double.parseDouble(JOptionPane.showInputDialog("Enter Investment Amount:"));

        duration = Double.parseDouble(JOptionPane.showInputDialog("Enter Duration in years: "));

        baserate = Double.parseDouble(JOptionPane.showInputDialog("Enter BaseRate:"));

        if (investment <- 50000){

        }
    }
}

我只是不确定如何为表创建决策语句......任何帮助？

由于您正在学习，我认为在尝试创建完整的图形应用程序之前，您应首先尝试使核心逻辑在控制台中运行。

尝试使用以下代码使其工作：

import java.util.Scanner;

class InvestGrowth {
  public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);

    System.out.print("Enter Investment ($):");
    double investment = scanner.nextDouble();

    System.out.print("Enter Duration (Years):");
    double duration = scanner.nextDouble();

    System.out.print("Enter Base:" );
    double base  = scanner.nextDouble();

    double growthRate = 0.0;
    double growthYield = 0.0;

    // TODO: Complete actual logic of calculating growthYield
    if (investment <= 50000) {
      if(duration <= 1) { // Investment <= $50000 && Duration <= 1 year

      } else { // Investment <= $50000 && Duration > 1 year

      }
    } else { 
      if (duration <= 1) { // Investment > $50000 && Duration <= 1 year

      } else { // Investment > $50000 && Duration > 1 year

      }
    }

    System.out.println("Your growth yield is: " + growthYield);
  }
}

我遗漏了核心逻辑，因为我认为这是你的作业（所以请问你的老师/讲师/教授/ TA等等。如果你被困住了）但你被困在＆＃34;决定的部分表格＃34; 的陈述是：）
