Java错误: ')' expected

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

有错误

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

它表示需要一个“)”。我明白它的意思，但我找不到括号缺少的地方......我很困惑。任何帮助将不胜感激!

Answer 1

您错过了 + 符号

"profit is " "$"
            ^

根据逻辑，我认为您实际上并不是要包含这些双引号:

"profit is $"
