Unknown error relating to syntax of tokens

Question

I can\'t work out what is wrong with the following code in Java:

import java.util.*;

public class stringCalculator {
    String operator_array[] = {\"+\", \"-\"         


        

Answer 1

You can not put statements directly inside a class.

Create a method or a constructor and put the call to put there.

public stringCalculator() {
    operatorPrecedence.put("+", "2");
}

Also, it is good practice to use an upper-case name for the class, like StringCalculator.
