java - Getting first element of specific type from ArrayList -


I have ArrayList type Animal . There are 10 references to objects in this list, which are 3 dogs, 3 cats and 4 birds. All three types ( dogs , cat and birds ) get from animals . Order of animals

Is there a more efficient way to get the first Cat from the list and use the instanceof operator?

Example. 

  cat cat = null; (Animal animal: list of animals) {if (animal for example cat) {cat = animal; break; }}    
 
 
 No, the actions you need to complete are as many as Quickly it happens: Searching for a particular  ArrayList  is always linear (i.e.  O (n) ).  
 In the context of readability, however, you can improve it by hiding the search in a supportive method, which takes a list and type, and finds the first occurrence of this type:  
  public stable   
 If you need to go faster than your search, you will need a different data structure.
