Java to sort list of custom object on the basis of string

Question

class Person 
 {
 private String name;
 private String profession;
}

profession has values:

• engineer
• Doctor<

Answer 1

My suggestion -

1. Create a new class Profession -

class Profession{

   public Profession(Integer id, String prefessionName){
      this.id=id;
      this.prefessionName=prefessionName;
   }
   Integer id;
   String professionName;

}  

2. Now give Id to each Profession object/instance maintaining the order. For example -

   Profession engineer = new Profession(1, "Engineer"); //since Engineer is in first place 
   Profession doctor = new Profession(2, "Doctor"); //since Doctor is in second place
   Profession teacher = new Profession(3, "Teacher");
   Profession student = new Profession(4, "Student");

3. Now sort the Profession for id using compareable interface.
