[Solved] Writing a java file [closed]

Question

The immediate issue is a missing open brace ({) and an closing parenthesis ())

public static void main(String[] args) {
                                       ^--- This is important...
    Scanner input = new Scanner( System.in); 
                                          ^--- Also important :P
    BufferReader br = new BufferReader(instream);

    System.out.println("Enter your annual sales");
    String annual = br.readLine();

    int salary = 75_502_81; 
    int com = 38_28; 
    int compensation = annual * com + salary;
}

There’s no such class as BufferReader, I think you mean BufferedReader

There’s no such variable instream declared in you code, I think you might mean input, but BufferedReader won’t take input as a valid input type, so I’m not sure what you intentions are here…

You’ll also be receiving warnings about an uncaught IOException

You can resolve these through the use of try-catch

I’m also curious about what 75_502_81 and 38_28 are suppose to mean? int values can’t contain anything other then numeric values…

annual is also String, meaning you can’t perform any mathematical operations on it.

You will need to convert the value to an int first…

public static void main(String[] args) {

    Scanner input = new Scanner( System.in ); 
    BufferedReader br = null;

    try {
        br = new BufferedReader(instream);
        System.out.println("Enter your annual sales");
        String annual = br.readLine();

        int salary = 7550281; 
        int com = 3828; 
        int compensation = Integer.parseInt(annual) * com + salary;

    } catch (IOException exp) {
        exp.printStackTrace();
    } finally {
        try {
            br.close();
        } catch (Exception exp) {
        }
    }
}

But I’m left scratching my head as to why, when

public static void main(String[] args) {

    Scanner input = new Scanner( System.in ); 
    System.out.println("Enter your annual sales");
    String annual = input.nextLine();

    int salary = 7550281; 
    int com = 3828; 
    int compensation = Integer.parseInt(annual) * com + salary;

}

Will do the same thing…
