Generate a random integer by using the random class <http://
java.sun.com/j2se/1.5.0/docs/api/java/util/Random.html> and then use
int bValue = randomInt % 2;
to get a o or 1 value.

Didn't the OP ask for boolean results?

to get a o or 1 value.

If {0,1} is really wanted, why not use myRandom.nextInt(2)? Or if a
boolean is wanted, myRandom.nextBoolean()?

The first step, of course, is for the OP to decide whether the values
should be boolean or {0,1}.

If {0,1} is really wanted, why not use myRandom.nextInt(2)? Or if a
boolean is wanted, myRandom.nextBoolean()?

In fact, nextInt(2) is much preferred to the modulus way of doing things
(i.e. randomInt % 2), since the mod method tends to give less random
results.
And if crypto grade (pseudo) randomness is required, used SecureRandom
or similar.
