How to filter an array in Java?

Question

How can I filter an array in Java?

I have an array of objects, for example cars:

Class:

public class Car{
    public int doors;
    public Ca         


        

Answer 1

You can use System.arrayCopy():

Car[] cars = ...
int length = cars.length < 4 ? cars.length() : 4;
Car filter = new Car[4];
System.arrayCopy(cars, 0, filter, 0, length);

UPDATE: System.arrayCopy is available in Java ME API, unlike Vector.subList(). Thanks for the correction.
