I have an interface Peron that has firstnamestring lastnames

I have an interface Peron that has firstname:string, lastname:string. I have a Class Professor implements Person has salary:Dollar, and Class Student implements Person has major:string. I need to write a program that compiles. I cannot upload the UML diagram.

Solution

import java.util.*;
public interface persom {
   String Fname=\"\";
   String Lname=\"\";
   public void getint();

}
class proffesor implements persom{
   String Fname;
   String Lname;
   int salary;
   public void getint(){
       Scanner sc=new Scanner(System.in);
       System.out.println(\"enter Fist name:\");
       Fname=sc.next();
       System.out.println(\"enter Last name:\");
       Lname=sc.next();
       System.out.println(\"enter salaruy:\");
       salary=sc.nextInt();
       System.out.println(\"Fname is\"+Fname);
       System.out.println(\"Lname is\"+Lname);
       System.out.println(\"major is\"+salary);
      
   }
  
  
}
class student implements persom{
   String Fname;
   String Lname;
   String major;
   public void getint(){
       Scanner sc=new Scanner(System.in);
       System.out.println(\"enter Fist name:\");
       Fname=sc.next();
       System.out.println(\"enter Last name:\");
       Lname=sc.next();
       System.out.println(\"enter major:\");
       major=sc.next();
       System.out.println(\"Fname is\"+Fname);
       System.out.println(\"Lname is\"+Lname);
       System.out.println(\"major is\"+major);
      
   }
}

public class mymainever {

   public static void main(String[] args) {
       student s=new student();
       //s.getint();
       persom p;
       p=s;
       p.getint();

   }

}
