令牌上的语法错误＆＃34;案例＆＃34;，断言预期

productNumber和numberOfProduct都是用户输入的int类型。 total和currentTotal的类型为double。

Switch (productNumber) //problem occurs here, at the switch statement and at each case
{
    case 1:
        currentTotal = numberOfProduct * 2.98;
        total += currentTotal;
        break;

    case 2:
        currentTotal = numberOfProduct * 4.50;
        total += currentTotal;
        break;

    case 3:
        currentTotal = numberOfProduct * 9.98;
        total += currentTotal;
        break;

    case 4://
        currentTotal = numberOfProduct * 4.49;
        total += currentTotal;
        break;

    case 5:
        currentTotal = numberOfProduct * 6.87;
        total += currentTotal;
        break;

    default:
        System.out.println("The number entered is not a known product number. Known product numbers are 1, 2, 3, 4, and 5.");
        --count;
}
