Java Error: ')' expected
提问by Salma
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 " "$" + (val3 - val1 * val2));
String pleaseContinue = bufRead.readLine();
System.out.println("Please press enter!");
This is just one part of my code. Unfortunately, the command prompt keeps telling me there's an error at
这只是我代码的一部分。不幸的是，命令提示符一直告诉我有一个错误
System.out.println("Hello, Donaldio! Your " + firstDepartment + "profit is " "$" + (val3 - val1 * val2));
It says that there's a ')' expected. I understand what it means, but I can't find where the parentheses is missing... I'm so confused. Any help would be greatly appreciated!
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！

You missed a +sign in between
你错过了+中间的一个标志
"profit is " "$"
^
Based on the logic, I think you actually don't mean to include those double quotes:
根据逻辑，我认为您实际上并不是要包含这些双引号：
"profit is $"

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