java - 收到类型错误的非法启动

Question

我收到此 block 的“非法类型开始”错误:

if (maritalStatus.equals("Single") || maritalStatus.equals("single")){
        taxableIncome = grossIncome - deductions - (dependents * allowance);
} else if (maritalStatus.equals("Married") || maritalStatus.equals("married")){
        taxableIncome = grossIncome - deductions - ((dependents + 2) * allowance);
}

另外，当涉及到单例/单例和已婚/已婚时，我该如何使用以下语句？

Boolean equalsIgnoreCase (String thisString)

Answer 1

我不知道为什么你的代码会出现错误，但你可以像这样使用 equalsIgnoreCase :

if (maritalStatus.equalsIgnoreCase("Single")) {
    taxableIncome = grossIncome - deductions - dependents * allowance;
} else if (maritalStatus.equalsIgnoreCase("Married")) {
    taxableIncome = grossIncome - deductions - (dependents + 2) * allowance;
}

我还去掉了你多余的括号。
