求计算本金之和的代码

                 static final double R=0.0225;
                    public static void main(String[] args)
                    {
                        int n;
                        double capital;
                        double deposit;
                        System.out.println("请输入存款期和存款本期为：");
                        Scanner bjh=new Scanner(System.in);
                        n=bjh.nextInt();
                        capital=bjh.nextDouble();
                         deposit=capital*Math.pow((1+R), n);                       
                        System.out.println("本金和为："+deposit);
                        
                        
                    }
