java - Sort an ArrayList by primitive boolean type

Question

I want to sort my ArrayList using a boolean type. Basically i want to show entries with true first. Here is my code below:

Abc.java

public class Abc {
 int id;
 bool isClickable;

 Abc(int i, boolean isCl){
    this.id = i;
    this.isClickable = iCl;
 }
 }

Main.java

List<Abc> abc = new ArrayList<Abc>();

//add entries here

//now sort them
Collections.sort(abc, new Comparator<Abc>(){
        @Override
        public int compare(Abc abc1, Abc abc2){

            boolean b1 = abc1.isClickable;
            boolean b2 = abc2.isClickable;

            if (b1 == !b2){
                return 1;
            }
            if (!b1 == b2){
                return -1;
            }
            return 0;
        }
    });

Order before sorting: true true true false false false false true false false

Order after sorting: false false true true true true false false false false

Another way to go is:

Collections.sort(abc, new Comparator<Abc>() {
        @Override
        public int compare(Abc abc1, Abc abc2) {
            return Boolean.compare(abc2.isClickable,abc1.isClickable);
        }
    });
