the following:

        public class Test1 extends MIDlet implements CommandListener {=

                public void startApp() {
                        Random rand = new Random();
                        System.out.println(rand.nextInt(5));
                }
        .
        .
        .

from the J2me compiler gets:

        home/kloro/cell/WTK2.2/apps/Test1/src/Test1.java:11: nextInt()=

in
                java.util.Random cannot be applied to (int)
        System.out.println(rand.nextInt(5));


That method doesn't exist in the J2ME version. The J2ME java.* classes =
 =

correspond to JDK 1.1 classes. The nextInt(int) method was introduced i=
n =

J2SE 1.2.

If you need this method, you can extend the Random class and add this =

method (just cut and paste it from the source of the Java SE version of =
 =

java.util.Random).

yet the doc' for Random states in the methods section:

        nextInt(int n) - Returns a pseudorandom, uniformly distributed=

int value
        between 0 (inclusive) and the specified value (exclusive),
drawn from this
        random number generator's sequence.
same type of result for long, double, short.


You're reading the wrong version of the documentation, you need the J2ME=
  =

docs.
