java - Java 错误: ')' 预期

Question

System.out.println("Enter a department name:");

String firstDepartment = bufRead.readLine();

System.out.println("Enter number of employees:");

val1 = Double.parseDouble(bufRead.readLine());

System.out.println("Enter cost per employee:");

val2 = Double.parseDouble(bufRead.readLine());

System.out.println("Enter sales:");

val3 = Double.parseDouble(bufRead.readLine());

System.out.println("Hello, Donaldio! Your " + firstDepartment + "profit is " "$" + (val3 - val1 * val2));

String pleaseContinue = bufRead.readLine();

System.out.println("Please press enter!");

这只是我的代码的一部分。不幸的是，命令提示符一直告诉我有一个错误

System.out.println("Hello, Donaldio! Your " + firstDepartment + "profit is " "$" + (val3 - val1 * val2));

它说有一个'）'预期。我明白这意味着什么，但我找不到括号丢失的地方......我很困惑。任何帮助将不胜感激！

Answer 1

您错过了+中间的登录

"profit is " "$"
            ^

根据逻辑，我认为您实际上并不是要包含那些双引号：

"profit is $"

Answer 2

System.out.println("Hello, Donaldio! Your " + firstDepartment + "profit is " "$" + (val3 - val1 * val2));

应该

System.out.println("Hello, Donaldio! Your " + firstDepartment + "profit is $" + (val3 - val1 * val2));
