What are the practical uses, purpose of random integer values.
// generates a random int
for (int i = 0; i < 10; i++) {
anyRandomInt(random);
}
System.out.println();
// generates a random int in a range from low int to high int
for (int i = 0; i < 10; i++) {
anyRandomIntRange(random, 1, 5);
}
int randomInt = random.nextInt(high) + low;

random.nextInt(high)
random.nextInt();
what is difference between below two lines belowThe javadoc for Random is pretty clear on this...
random.nextInt(high)
random.nextInt();
Returns a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive) ...(Note the inclusive and exclusive in the above quote). So if for example 'high' = 8, it returns a random number that can have any value from the following... 0, 1, 2, 3, 4, 5, 6, or 7
Returns the next pseudorandom, uniformly distributed int value ... All 2^32 possible int values are produced with (approximately) equal probabilitySo this returns a random number in the full range that an int can represent,
turns a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive) ...
