Java Priority Queue

  • [deleted]     + 2 comments

    Just use this comparator in the Student class and while instantiating the priority queue pass it as an argument.

     public static Comparator<Student> studentComparator = new Comparator<Student>(){
         
        @Override
        public int compare(Student student1, Student student2) {
            if(student1.getCgpa()<student2.getCgpa())
                return 1;
    else if(student1.getCgpa()>student2.getCgpa())
                return -1;
           else{
    if(!student1.getFname().equals(student2.getFname()))
return student1.getFname().compareTo(student2.getFname());
  else{
      return(student1.getToken()-student2.getToken());
     }
   }
  }
};

    Sorry for the bad indentation!
