java在数组中计算工资并返回答案

Question

问题是：

Write a method that takes in an array of salary values and a double rise rate, to calculate and return the array of salaries after they are raised. If, for example, the rise rate is 1.07 and one has the salary of £20000, then after raising the salary is 20000 X 1.07 = 21400.

请注意：这不是一个家庭作业，而是来自软件与技术部的过去考试题；编程1，BikBek，伦敦大学。

到目前为止，我有，但我不认为这是非常正确的，因为编译后，我需要单击inspect

public class salary
{
    public static double [] salary ()
    {
        double [] salary = {20000};
        riseRate = 1.07;
        for (int i = 0; i<salary.length; i++)
        {
            salary [i] = salary[i] * riseRate;
        }
        return salary;
    }
}

Answer 1

Write a method that takes in an array of salary values and a double rise rate

public static void foo(double[] salaries, double riseRate){...}

return the array of salaries after they are raised

public static double[] foo(double[] salaries, double riseRate){...}

If, for example, the rise rate is 1.07 and one has the salary of £20000, then after raising the salary is 20000 X 1.07 = 21400

public static double[] foo(double[] salaries, double riseRate){
    for(double salary : salaries){
        salary *= riseRate;
    }  
    return salaries;
}
