Within the constructor for this class, the parameter names stuNum and gpa are identical to the class field names. Within the constructor, stuNum and gpa refer to the locally declared names, not the class field names. The statement stuNum = stuNum accomplishes nothing because it assigns the local variable value to itself.?One way to fix the problem with the Student class is to use different identifiers for the class's fields and the parameters to the constructor. However, sometimes the identifiers you have chosen are the best and simplest identifiers for a value. If you choose to use the same identifiers, you can use the this reference explicitly to identify the fields. When the this reference is used with a field name in a class method, the reference is to the class field instead of to the local variable declared within the method.
