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));

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.

Which documentation are you using for the J2ME API?

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 in
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).

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

following is the url of the doc' section from which i quoted, as set up
by the WTK2.2 installer:


file:///home/kloro/cell/WTK2.2/docs/api/midp/java/util/Random.html#next(int)

sorry, make that url:
