Java 实例 计算复合利率

P (1 + R/n) (nt) - P

P = 2000
R = 8/100 = 0.08（十进制）
n = 12
t = 5

复利 = 2000 (1 + 0.08 / 12) (12 * 5) - 2000 = $ 979.69

public class JavaExample {

    public void calculate(int p, int t, double r, int n) {
        double amount = p * Math.pow(1 + (r / n), n * t);
        double cinterest = amount - p;
        System.out.println("Compound Interest after " + t + " years: "+cinterest);
        System.out.println("Amount after " + t + " years: "+amount);
    }
    public static void main(String args[]) {
        JavaExample obj = new JavaExample();
        obj.calculate(2000, 5, .08, 12);
    }
}

Compound Interest after 5 years: 979.6914166032102
Amount after 5 years: 2979.69141660321
