Java錯誤：'）'預計

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!"); 

這只是我的代碼的一部分。不幸的是，命令提示符不斷告訴我有一個錯誤在

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

它說，有一個'）'的預期。我明白這意味着什麼，但我找不到括號丟失的地方......我很困惑。任何幫助將不勝感激！

Answer 1

你錯過了在基於邏輯

之間

"profit is " "$" 
      ^

一個+標誌，我覺得你其實並不意味着包括雙引號：

"profit is $" 

Answer 2

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

應該

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