Java-For循环（执行/执行）无限期重复

Question

我一直在为我的课程设计一个项目。 这是一个简单的薪水计算器，我已经很轻松地弄清楚了，它的功能也很完美。 它还考虑了佣金基准。 但是，我已经完成了最后一部分。 我无法使其正常运行。 它可以无限循环，也可以在“总补偿”列下生成静态数字（根据佣金等，它们应该是动态的）。

• 鲍勃一年赚85,000美元。
• 如果他的销售额低于$ 120,000，他将不会获得奖金/佣金
• 如果他当年的销售额> = $ 120,000，他将获得15％的佣金
• 每15万美元的销售额（15万，30万，45万等），他将获得2％的额外回报

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

左侧为潜在销售，右侧为总薪酬

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

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

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

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

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

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

        int BaseSalary;

        }

        else if(Sales < TargetSales)
        {
            TotalCompensation = BaseSalary + Commission;
            System.out.print("\nCommission Goal HAS been met");
            System.out.println("\nTotal annual compensaton is: ");
            System.out.println(numberFormat.format(TotalCompensation));
        }

        else if(Sales >= TargetSales)
        {

        }

// Potential Commission Structure Table

        double PotentialSales;
        double EndLoop = (Sales * 1.5);
        int Increment = 20000;

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

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

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

            }          

任何建议或技巧都将成为救命稻草。

Answer 1

此代码将迭代直到表达式(PotentialSales < AcceleratorGoal)为false为止。 由于您没有在do{..body..}while(expression)的正文中更新PotentialSales ＆ AcceleratorGoal的值，因此如果(PotentialSales < AcceleratorGoal)首先为true ，它将无限期地进行迭代，否则它将被执行一次并且在while条件之后将转到下一条语句。

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do while循环主体内的PotentialSales或AcceleratorGoal值，或更改wrt output变量的条件。

接下来的两个do..while循环也是如此。

Answer 2

您的do while循环无限重复，因为您没有在do while循环中更新PotentialSales的值

要了解问题，请检查以下代码

int accelerationsales=5;
for(int potentialsales=0;potentialsales<5;potentialsales=potentialsales+=1) {
do {
    System.out.println("Hello");
   } while(potentialsales<accelerationsales);
}

运行此示例代码，您将了解问题。
