Given the following Person class, write a Boolean method called somethingsWrong() to determine if two instances of Person have different names, but the same SSN. The somethingsWrong () method should be true if the two people have the same social security number (SSN) but one or both of their names are not the same.

Expert Solution
Step 1: Solution

Question given:

A scratch code of a class and it's methods is given. Define a new method boolean somethingsWrong() within this class, that check if two different instances of this class have same ssn number but not have same names.

 

Programming language used: Java

 

Source code in Java:

(Note: all necessary comments are included in source code)

 

class Person {
    private String firstName = "";
    private String lastName = "";
    private String ssn = "";
    Person(String firstName, String lastName, String ssn){
        this.firstName = firstName;
        this.lastName = lastName;
        this.ssn = ssn;
    }
    public String getSSN() {
        return this.ssn;
    }
    public String getFirstName(){
        return this.firstName;
    }
    public String getLastName(){
        return this.lastName;
    }

    // other methods 
    public boolean somethingsWrong(Person p1, Person p2){
        // get first person's full name 
        String p1_full = p1.getFirstName()+" "+p1.getLastName();
        // get second person's full name 
        String p2_full = p2.getFirstName()+" "+p2.getLastName();
        
        // check if both instances have same ssn number
        if(p1.getSSN() == p2.getSSN()){
            // check if both instances have not same name  
            if(p1_full != p2_full){
                // if both conditions are true, then return boolean true
                return true;
            }
        }
        // if any condition is false then return boolean false
        return false;
    }
}

// create test class 
public class PersonTest{
    public static void main(String[] args) {
        // create 2 instances of Person class
        Person p1 = new Person("Daniel", "Jones", "123294");
        Person p2 = new Person("Alex", "Hope", "123294");

        // call somethingsWrong() method by any class's object and passed both instances as paramter
        System.out.println("Result: "+ p1.somethingsWrong(p1, p2));
    }
}
