预期的令牌空白语法错误？

Question

我对编码有点陌生，不明白为什么会出现这种情况。有人请帮忙。

导入 java.util.Scanner;

类calculateMortgageA { 公共静态 void main (String[]args) {

//create scanner 
Scanner input =new Scanner (System.in);

//prompt user to write in salaries so they can be read in while declaring the variables for the salaries
System.out.println("Enter person 1's salary:");
double salaryOne = input.nextDouble();

System.out.println("Enter person 2'a salary:");
double salaryTwo=input.nextDouble();

//calculate the mortgage 
System.out.print("The mortgage will be £" + calcmortgage(salaryOne,salaryTwo));

input.close();

}

public static double calcmortgage（双薪一，双薪二）{

    double mortgage;

    if (salaryOne > salaryTwo)
           mortgage = 3*salaryOne + salaryTwo;
           return mortgage;

    
    else (salaryTwo > salaryOne)
           mortgage = 3*salaryTwo + salaryOne;
           return mortgage;

}

}

Answer 1

看起来您缺少 if 和 else 块周围的花括号：

public static double calcmortgage (double salaryOne, double salaryTwo) {

    double mortgage;

    if (salaryOne > salaryTwo) { // Here
           mortgage = 3*salaryOne + salaryTwo;
           return mortgage;
    } // And here
    else (salaryTwo > salaryOne) { // And here
           mortgage = 3*salaryTwo + salaryOne;
           return mortgage;
    } // And here
}
