I have an arraylist of database records. I want to put it in my J2ME List. But there is no split or arraylist in J2ME. How can I do it? A code example would be nice.

    http://docs.oracle.com/javame/config/cldc/ref-impl/midp2.0/jsr118/java/util/Vector.html

    public void asd(){
        MyObject mo = new MyObject();
        Vector v = new Vector();
    
        //Adds the specified component to the end of this vector, increasing its size by one.
        v.addElement(mo);
    
        //Returns the component at the specified index.
        mo = (MyObject)v.elementAt(0);
    }

    It is better if you use Vector (java.util.Vector). It will help you.

    J2ME has Vector, which is the same as ArrayList, but all its methods are synchronized (a little bit slower).
