sorting two times based on status and title java android -

well have class named data:

public class data implements comparable<data>{     public string title;     public string description;     public string inststatus;     public int imageid;      data(string title, string description, int imageid,string inststatus) {         this.title = title;         this.description = description;         this.imageid = imageid;         this.inststatus = inststatus;     }      @override     public int compareto(data another) {          if(this.inststatus.equals("present")){             return this.title.compareto(another.title);         }else // not present         return this.inststatus.compareto(another.inststatus); // ascending       }  } 

now if see class comparing based on title in ascending order want sorting on 2 rules

inststatus has 2 values :- "present" , "not present" 1. inststatus = "present" should come on top , after that, of them should sort in ascending order 2. inststatus = "not present" should come on bottom , after that, of them should sort in ascending order

now let's take example have list of values

title = abc ,status = present title = bcd , status not present title = xyz ,status = present title = aac ,status not present 

now after above 2 rules, should after sorting

1. abc // present , ascending 2. xyz 3. aac // left ones not present , ascending 4. bcd 

so, inststatus more important title. right? if then, first should check inststatus , if inststatus same after should check titles. if inststatus not same , if object present means other 1 not-present can return 1. rest same. if not present return -1.

you can implement following.

public int compareto(data another){      if(inststatus.equals(another.inststatus)){         return title.compareto(another.title);     }     return inststatus == "present" ? 1: -1;  }
