java - 增加 Java 中用户输入的百分比

Question

如果用户输入高于 100，则每个单位增加 5%，即 100 或减去返回 5%、101 返回 10%、102 返回 15%，依此类推。

到目前为止我能够做到这一点:

public class CalculatePercent {
    private  int numberGiven;
    private int finalPerc;

    public String numberGiven(int numberGiven) {
        this.numberGiven = numberGiven;

        if(numberGiven == 100) {
            finalPerc=5;
            return "The percentage" + " " + "is:" + " " + finalPerc + "%";
        }
        else if (finalPerc > 100 ) {

        }
        return finalPerc;
    }
}

还有这个:

import java.util.Scanner;

public class CalculatorApp {


    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
            CalculatePercent p = new CalculatePercent(); 

        System.out.println("Type the number: ");
        String usernumber = p.numberGiven(in.nextInt());
        System.out.println(usernumber);
    }

}

Answer 1

public class CalculatePercent {

    private int numberGiven;
    private int finalPerc;

    public String numberGiven(int numberGiven) {
        this.numberGiven = numberGiven;
        if (this.numberGiven <= 100) {
            finalPerc = 5;
        } else if (this.numberGiven > 100) {
            finalPerc = 5 * (this.numberGiven - 99);
            /*
                Why 99 ?
                For examaple :
                100 - 99 = 1 * 5 = 5%;
                101 - 99 = 2 * 5 = 10%;
                102 - 99 = 3 * 5 = 15%
                soon
            */
        }
        return "The percentage" + " " + "is:" + " " + finalPerc + "%";
    }
}
