这段代码演示了如何根据员工类型（普通员工、程序员、设计师、架构师）进行数据统计，包括年龄、工资和收入的总和及平均值计算。通过switch-case语句将员工分配到对应的类别，并使用Count02类进行数据累加。最后输出各类员工的统计数据。





class Count02 {
    int sum_age;
    int sum_wages;
    int sum_income;
    int count;

    public void add(Employees02 e, int i) {
        sum_age += Integer.parseInt(e.employees[i][3]);
        sum_wages += Integer.parseInt(e.employees[i][4]);
        sum_income += Integer.parseInt(e.employees[i][4]);
        count++;
        if (e.employees[i].length > 5) {
            sum_income += Integer.parseInt(e.employees[i][5]);
            if (e.employees[i].length > 6) {
                sum_income += Integer.parseInt(e.employees[i][6]);
            }
        }
    }
}

    class Employees02 {
        String[][] employees = {
                {"10", "1", "段誉", "22", "3000"},
                {"13", "2", "令狐冲", "32", "18000", "15000", "2000"},

        };
    }
