Does Random with zero seed work ?

Question

halo everyone..
i am new to this site.. and im very new to java too.
anyways.. i am so stomped.. how can i make a
random constructor to accept a zero seed and still
generate a random number ?
coz when i try like
Random generator = new Random(0);
all my generated integers stay the same..
not random at all.
i tried to use DecimalFormat to try and work around
this problem.. but still it doesn't work for me. i would like
to know if this is possible to have zero seed. thanx

You must be using it incorrectly. You're probably doing something like this: for (...) {
    Random rand = new Random(0);
    int value = rand.nextInt();
} You need to do this: Random rand = new Random(0);
for (...) {
    int value = rand.nextInt();
} Or, if rand is a member variable in your class, make it static, so all instances share the same Random.
If you create multiple Randoms with the same seed, they'll all have the same sequence of pseudorandom numbers. If you only use each one once, you'll always get the first number in that sequence.
