Question

我在初学者Java课程中遇到了麻烦。我需要让我的程序将佣金率从一个数组拉到输出中。其他一切似乎都在起作用，但它不会计算佣金，我不确定我错过了什么。任何帮助都会很精彩！

    public class Annualwages extends salesperson
     {

       /** @param args the command line arguments     */

        public static void main(String[] args) 
        { //begins the main method

         salesperson sp = new salesperson();
         sp.saleInformation();


            System.out.println("You entered the following:");

            System.out.println();
              for (int index = 0; index < sp.salesP.length; index++) 
             {
                System.out.println("Sales Person " + (index + 1));
                System.out.println("   Name: "
                        + sp.salesP[index]);
                System.out.println("   Total Annual Sales: "
                        + sp.sales[index]);
                System.out.println("   Base Salary is: " + sp.SALARY);
                System.out.println("   Annual Commission is: "
                        + sp.comm[index]);
                System.out.println("   Total Annual Compensation is: "
                        + sp.totalWages );
                System.out.println();

你有一些错误。

计算佣金时，您没有为comm[index]分配任何值。不要使用actualCommission变量（您实际上从未显示过），只需直接指定给comm[index]。
变量sales.length不太可能达到96000或更高，因为它是您投入的销售数量。因此，第一个if条件将每次返回true时间，你最终将佣金设置为零。也许你的意思是写if (sales[index] <= 96000)。对于涉及sales.length的其他比较也是如此。

需要将佣金率从一个阵列提取到输出中
