Question

我正在为类Project构建一些东西，代码仍然很混乱，请忽略它。我问的问题是如何解决这个错误：

===================================

员工姓名| 尚史

工作小时数| 40

每小时费率| 9.75

员工姓名| //注意这里跳过输入问题＆＃34;员工姓名＆＃34;

工作小时数|

Answer 1

您的for循环遇到问题，特别是您的j循环和i循环。 i循环位于j循环内部，看起来好像不应该循环。你应该

for(j = 0; j < 3; j++) {
/*  System.out.println();
    System.out.println("Employee Name |");
    name[j] = Board.nextLine();
    System.out.println("Hours Worked |");
    hourWages[j] = Board.nextInt();
    System.out.println("Hourly Rate |");
    hourRate[j] = Board.nextDouble();      */

    grossPay[j] = hourWages[j] * hourRate[j];
    fedTax[j] = grossPay[j] * .18;
    stateTax[j] = grossPay[j] * .045;
    netPay[j] = grossPay[j] - (fedTax[j] + stateTax[j] + HOSPITALIZATION + UNIONDUES);
}

// the loop above is complete; now we start the next one

for(i = 0; i < 3; i++) {
    System.out.println("Employee    |           " + name[i]);
    System.out.println("Hours Work  |           " + hourWages[i]);
    System.out.println("Hourly Rate |           " + hourRate[i]);
    System.out.println("Gross Pay   |           " + grossPay[i]);
    System.out.println("");  //- < Blank!
    System.out.println("Deductions:                    ");
    System.out.println("Federal Withholding |          " + fedTax[i]);
    System.out.println("State WithHolding |            " + stateTax[i]);
    System.out.println("Hospitalization |              " + HOSPITALIZATION);
    System.out.println("Union Dues |                   " + UNIONDUES);
    System.out.println("                               -----");
    System.out.println("Total Deductions |             " + deductions[i]);
    System.out.println("                               ");
    System.out.println("NetPay |                       " + netPay[i]);
}

这导致您遇到麻烦的原因是，当您仅计算第一个员工的结果时，您将为第二个和第三个员工打印输出。

Answer 2

我想这个问题是由于使用了nextLine。在实际读取输入之前使用虚拟nextLine。这将在nextxxx之后读取并刷新输入，然后读取新的。或者您可以尝试使用next代替。
