We Have Already Coded the Class User

Essay

We have already coded the class User. It includes the instance variables name, age, and email, an overloaded constructor, and the toString method coded as follows:
public String toString( )
{
// return some String representation of this User object
}
We are now coding the class SuperUser, which inherits from User. SuperUser has one instance variable, fee, which is a double. We want the toString method of the SuperUser class to return the same String as the toString method of the User class, plus a semicolon, a space, and the value of fee.
Example 1: If the toString method of User returns Mike, 23, HYPERLINK "mailto:[e-mail]" [e-mail], and the value of fee is 19.9, the toString method of SuperUser returns Mike, 23, HYPERLINK "mailto:[e-mail]" [e-mail], 19.9.
Example 2: If the toString method of User returns Jane, 22, HYPERLINK "mailto:[e-mail]" [e-mail], and the value of fee is 24.9, the toString method of SuperUser returns Jane, 22, HYPERLINK "mailto:[e-mail]" [e-mail], 24.9.
Code the toString method of the SuperUser class here. Assume that we do not know what the toString method of User returns.
