How to filter an array in Java? -

how can filter array in java?

i have array of objects, example cars:

class:

public class car{     public int doors;     public car(int d){         this.doors = d;     } } 

use:

car [] cars = new cars[4]; cars[0] = new car(3); cars[1] = new car(2); cars[2] = new car(4); cars[3] = new car(6); 

now want filter array of cars, keeping 4 doors , more:

for(int = 0; i<cars.length; i++){     if(cars[i].doors > 4)          //add cars[i] new array     } } 

how should this?

before did vector:

vector subset = new vector(); for(int = 0; i<cars.length; i++){     if(cars[i].doors > 4)          //add cars[i] new array         subset.addelement(cars[i]);     } } 

and make new array size of vector. loop on vector again , fill new array. know large procedure simple.

i'm using j2me.

edit: saw arraylist not in j2me, based on documentation, have vector. if vector class different j2se vector (as this documentation indicates), perhaps following code work:

vector carlist = new vector(); for(int = 0; i<cars.length; i++){     if(cars[i].doors > 4)          carlist.addelement(cars[i]);     } } car[] cararray = new car[carlist.size()]; carlist.copyinto(cararray);
