The accepted solution fails to meet either requirement.Your answer is perfect and excellent but i got the answer before your post.You just copied LanguidSquid code and updated. The code to use the nextInt method is this. additionally, it makes no attempt to avoid duplicate numbers.the question was edited to remove the duplication stipulation, and the author stated in a comment that zeroes were significant (see the comments above). Generates the next pseudorandom number.

Stack Overflow works best with JavaScript enabled Random class is used to generate pseudo-random numbers in java. n − This is the bound on the random number to be returned.
Returns the next pseudorandom, uniformly distributed Returns the next pseudorandom, Gaussian ("normally") distributed Sorry, we no longer support Internet Explorer Where developers & technologists share private knowledge with coworkersProgramming & related technical career opportunitiesTry this: [Generating random integers in a range with Java][1] [1]: i know to create random numbers . edit. the length of the byte array. Don’t stop learning now. The algorithms implemented by class Random use a protected utility method that on each invocation can supply up to 32 pseudorandomly generated bits. Any of those characters can be arbitrarily zero or one. The min parameter (the origin) is inclusive, whereas the max, the bound, is exclusive. did you mean that generated numbers should not repeat?should leading zeroes be counted towards the "length" of the number (for example, would yes at last i made it .

Return Value.
int randomWithRange(int min, int max) { int range = (max - min) + 1; return (int)(Math.random() * range) + min; } Output of randomWithRange(2, 5) 10 times: 5 2 3 3 2 4 4 4 5 4 The bounds are inclusive, ie [2,5], and min must be less than max in the above example. Featured on Meta Exception. modified using a linear congruential formula. worst case is n=2^30+1, for which the probability of a reject is 1/2, To generate a number between 10 to 20 inclusive, you can use Here's a method which receives boundaries and returns a random integer. independently chosen bits. public int nextInt() Returns: the next pseudorandom, uniformly distributed int value from this random number generator's sequence; java.util.Random.nextInt(int bound): Returns a pseudo random, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive), drawn from this random number generator’s sequence Syntax: Random’s nextInt method will generate … An instance of this class is thread-safe.
