Question

I have a Fruit model class:

public class Fruit{
   private String name;
   private String color;

   public Fruit(String name, color){
     this.name = name;
     this.color = color;
   }
   public getName(){
      return name;
   }
   public getColor(){
      return color;
   }
}

Then, I created a list of fruits:

List<Fruit> fruits = new ArrayList<Fruit>();

fruits.add(new Fruit("Orange","orange"));
fruits.add(new Fruit("Strawberry","red"));
fruits.add(new Fruit("Apple","green"));
fruits.add(new Fruit("Banana","yellow"));

Now, I would like to sort the fruits elements in alphabetical order in terms of fruit name . How can I efficiently sort the fruits list?

Answer 1

use the following

Collections.sort(fruits);

public class Fruit implements Comparable {

    public int compareTo(Object o) {            
        Fruit f = (Fruit) o;
        return this.getName().compareTo(f.getName());
    }

}
