我必须创建一个工资/奖金计算器。
根据输入的薪水，奖金将更高或更低/
例如。低于20000的将是7％，超过该数字的将是5.5％。
最后，我要显示奖金的总额和奖金的薪金总额。
程序完成后，我在总数上遇到了麻烦。
这是我的代码。
class Salaries
{
public static void main(String agrs[])
{
int salary; // this takes in each salary
double salaryTotal = 0; // this adds the bonus to to salary
double bonus = 0; // this hold the bonus amount.
double sumSalary=0;
double sumBonus=0;
String exit = "y";// This is the string to be entered to exit the loop.
// below I'm using a do/while loop to keep it going till a key that isn't "y is entered"
do
{
// the try/catch makes sure that only a number is entered.
try{
// below prompts the user to enter the salary amount
System.out.println("Enter an Employes wages.");
// below takes in the salary
salary = EasyIn.getInt();
// if else ensure that the salary is not below 0
// and to determine if the amount of bonus to be added.
if (salary <=-1)
{
System.out.println("The salary can not be less than 0");
}
else if (salary >0 && salary <=20000)
{
bonus = salary*7/100; // This takes the entered salary and calculates the bonus.
salaryTotal = salary + bonus;
System.out.println("The bonus paid is " + bonus);
System.out.println("********************");
System.out.println("The total salary + bonus is " + salaryTotal);
System.out.println("********************");
System.out.println("Enter y to enter another Employes wages. ");
System.out.println("Press any other letter to exit.");
System.out.println("********************");
System.out.println();
exit = EasyIn.getString();
}
else if (salary >20000 && salary <=30000)
{
bonus = salary*5.5/100; // This takes the entered salary and calculates the bonus.
salaryTotal = salary + bonus;
System.out.println("The bonus paid is " + bonus);
System.out.println("********************");
System.out.println("The total salary + bonus is " + salaryTotal);
System.out.println("********************");
System.out.println("Enter y to enter another Employes wages. ");
System.out.println("Press any other letter to exit.");
System.out.println("********************");
System.out.println();
exit = EasyIn.getString();
}
else if (salary >30000 && salary <=40000)
{
bonus = salary*4/100;
salaryTotal = salary + bonus; // This takes the entered salary and calculates the bonus.
System.out.println("The bonus paid is " + bonus);
System.out.println("********************");
System.out.println("The total salary + bonus is " + salaryTotal);
System.out.println("********************");
System.out.println("Enter y to enter another Employes wages. ");
System.out.println("Press any other letter to exit.");
System.out.println("********************");
System.out.println();
exit = EasyIn.getString();
}
else if (salary >40000)
{
bonus = salary*3.5/100;
salaryTotal = salary + bonus; // This takes the entered salary and calculates the bonus.
System.out.println("The bonus paid is " + bonus);
System.out.println("********************");
System.out.println("The total salary + bonus is " + salaryTotal);
System.out.println("********************");
System.out.println("Enter y to enter another Employes wages. ");
System.out.println("Press any other letter to exit.");
System.out.println("********************");
System.out.println();
exit = EasyIn.getString();
}
}
catch(Exception e)
{
System.out.println("ERROR!!!! Please enter a number.");
}
}
while(exit.equals("y"));
System.out.println("The total amout of bonus is " + sumBonus );
System.out.println("The total of all the salaries is " + sumSalary);
}
}
最佳答案
使这个加倍。 int和double之间的除法可能导致返回整数。
int salary; // this takes in each salary

同样，进行奖金计算会更加有效：
bonus = salary * 0.055;
我也没有看到您将值从奖金移动到sumBonus的位置：
System.out.println("The total amout of bonus is " + sumBonus );
也许将sumBonus更改为bonus，不要忘记删除声明。
