Java - For 循环(do/while)无限重复

Question

我一直在为我的类(class)开发一个项目。这是一个简单的工资计算器，我很容易就学会了，而且功能完美。它还考虑了佣金基准。不过，我已经完成了最后一部分的切割。我无法让它发挥作用。它要么无限循环，要么在“总薪酬”列下生成静态数字(它们应该根据佣金等动态)。

• 鲍勃每年赚取 85,000 美元。
• 如果他的销售额低于 120,000 美元，他就不会获得奖金/佣金
• 如果他当年的销售额 >= 120,000 美元，他将获得 15% 的佣金
• 每销售额 15 万美元，他可获得 2% 的额外提成(15 万、30 万、45 万)等)

用户输入销售数字(例如:300,000 美元)。程序计算 BaseSalary + ($300,000 * .15) + ($300,000 * .02)

左侧是潜在销售额，右侧是总薪酬

200,000 ----------------------> (Calculated)

220,000 ----------------------> (Calculated)

240,000 ----------------------> (Calculated)

260,000 ----------------------> (Calculated)

280,000 ----------------------> (Calculated)

300,000 ----------------------> (Calculated)

        int Increment = 20000;

            System.out.println("\nPotential Sales\t\tTotal Compensation");

            for (PotentialSales = Sales; PotentialSales < EndLoop; 
            PotentialSales = PotentialSales += Increment)   
            {

                do

                    + numberFormat.format(BaseSalary);

                    System.out.println(output);
                }   
                    while(PotentialSales < AcceleratorGoal);

                do
                {
                    String output = numberFormat.format(PotentialSales) + "\t\t" 
                    + numberFormat.format(Commission + BaseSalary);

                    System.out.println(output);
                }
                    while(PotentialSales >= AcceleratorGoal && PotentialSales < TargetSales);

                do
                {
                    String output = numberFormat.format(PotentialSales) + "\t\t" 
                    + numberFormat.format(AcceleratedCommission + BaseSalary);

                    System.out.println(output);
                }
                    while(PotentialSales >= TargetSales);

            }          

任何建议或提示都将是救星。

Answer 1

此代码将迭代直到表达式 (PotentialSales < AcceleratorGoal)是 false 。由于您没有更新 PotentialSales 的值& AcceleratorGoal在 do{..body..}while(expression) 的体内，如果 (PotentialSales < AcceleratorGoal) ，它将无限迭代是 true首先，否则它将执行一次并转到while之后的下一条语句。健康)状况。

代码

do{
    String output = numberFormat.format(PotentialSales) + "\t\t" + numberFormat.format(BaseSalary);                   
    System.out.println(output);
}while(PotentialSales < AcceleratorGoal);

您可能想要更新 PotentialSales或AcceleratorGoal do while 循环体内的值或更改条件 w.r.t output变量。

接下来的两个do..while也是如此循环。
