java - 使用数组存储纳税人信息

Question

如果我要求“x”税额又如何

Answer 1

在 do-while 循环之前初始化 children 和 grossIncomes 数组。

延长 do-while 循环直到 JOptionPane.showMessageDialog(null,message);

请勿使用numTaxpayers作为children和grossIncomes的索引。使用 count，并在循环开始之前将 count 初始化为 0。

            int[] children = new int[numTaxpayers];
            double[] grossIncomes = new double[numTaxpayers];
            int count = 0;
            while (count < numTaxpayers)
            {
                int numChildren = Integer.parseInt(JOptionPane.showInputDialog("How many children do you have?"));
                double grossIncome = Double.parseDouble(JOptionPane.showInputDialog("What is your gross income?"));

                children[count] = numChildren;
                grossIncomes[count] = grossIncome;

                count ++;
                // Calculations goes here
                //....
                //...
                JOptionPane.showMessageDialog(null,message);
             }
