虽然循环不重复

Question

I have having a hard time getting this while loop to execute. I tried it without resetting the scanner first, and it would loop but throw the second line immediatly with the first line, so It was suggested to add the scanner reset lines. Now the loop does not repeat at all....any suggestions? I am looking at the first while loop in the main program, that is supposed to repeat the entire program until "quit" is entered into the empName field. Not the smaller while loops nested in the middle.

 Scanner input;
   empName = " ";
   while (!empName.equals("quit"))
   {
     input = new Scanner (System.in);
     System.out.print( "Enter employee name or enter 'quit' when finished. " );
     empName = myScanner.nextLine();
     hourlyRate = -1;
     while (hourlyRate <= 0)
     {
       System.out.print( "What is their hourly rate? $");
       hourlyRate = myScanner.nextDouble();
       if (hourlyRate <= 0)
       {
           System.out.println( "Value is not valid, please enter an amount above zero.");
       }
     }
     totHours = -1;
     while (totHours <= 0)
     {
         System.out.print( "How many hours did they work? ");
         totHours = myScanner.nextDouble();
         if (totHours <= 0)
         {
            System.out.println( "Value is not valid, please enter an amount above zero.");
         }
     }
     if (totHours > 40.00)//Calculate Pay and Taxes if OT
     {
        otHours = totHours - 40;
        regHours = totHours - otHours;
        otPay = (1.5 * hourlyRate) * otHours;
        regPay = hourlyRate * regHours;
        grossPay = regPay + otPay;
        taxes = grossPay * .13;
        netPay = grossPay - taxes;
//Display OT information
        System.out.print( "Employee name: ");
        System.out.println(empName);
        System.out.print( "Hourly Rate: ");
        System.out.println(money.format(hourlyRate));
        System.out.print( "Regular Hours Worked: ");
        System.out.println(regHours);
        System.out.print( "OT Hours Worked: ");
        System.out.println(otHours);
        System.out.print( "Total Hours Worked: ");
        System.out.println(totHours);
        System.out.println("   ");
        System.out.print( "Regular Pay = ");
        System.out.println(money.format(regPay));
        System.out.print( "Overtime Pay = ");
        System.out.println(money.format(otPay));
        System.out.print( "Gross Pay = ");
        System.out.println(money.format(grossPay));
        System.out.print( "Federal Taxes = ");
        System.out.println(money.format(taxes));
        System.out.println( "   ");
        System.out.print( "Net Pay = ");
        System.out.println(money.format(netPay));
     }
     else //Calculate No OT Pay and Taxes
     {
        grossPay = hourlyRate * totHours;
        taxes = .13 * grossPay;
        netPay = grossPay - taxes;
//Display No OT Information
        System.out.print( "Employee name: ");
        System.out.println(empName);
        System.out.print( "Hourly Rate: ");
        System.out.println(money.format(hourlyRate));
        System.out.print( "Hours Worked: ");
        System.out.println(totHours);
        System.out.println( "   ");
        System.out.print( "Gross Pay = ");
        System.out.println(money.format(grossPay));
        System.out.print( "Federal Taxes = ");
        System.out.println(money.format(taxes));
        System.out.println( "   ");
        System.out.print( "Net Pay = ");
        System.out.println(money.format(netPay));
        System.out.println( "   ");
     }
   String clearBuffer = input.nextLine();
   }
   }
}

Answer 1

Adding the third line of the following block (at the point where you read the employee name) is the way to fix this with the fewest changes to your code.

 System.out.print( "Enter employee name or enter 'quit' when finished. " );
 empName = myScanner.nextLine();
 if(empName.equals("quit")) break;
