How do I split strings in J2ME?

Question

How do I split strings in J2ME in an effective way?

There is a StringTokenizer or String.split(String regex) in the standard edition (J2SE), but they are absent in t

Answer 1

There is no built in method to split strings. You have to write it on your own using String.indexOf() and String.substring(). Not hard.

Answer 2

In J2ME no split, but you can use this code for split.This code works with only 1 simbol delimiter!!! Use NetBeans.File\Create Project\ Java ME\ MobileApplication\Set project name(split)\Set checkmark.Delete all code in your (Midlet.java).Copy this code and past in your (Midlet.java).

}

Splited elements located in array called (out).For Example out[1]:Hello. Good Luck!!!
