  • Method Details

    • setSeed

      void setSeed​(int seed)
      Deprecated.
      Sets the seed of the underlying random number generator using an int seed.

      Sequences of values generated starting with the same seeds should be identical.

      Parameters:
      seed - the seed value

    • setSeed

      void setSeed​(int[] seed)
      Deprecated.
      Sets the seed of the underlying random number generator using an int array seed.

      Sequences of values generated starting with the same seeds should be identical.

      Parameters:
      seed - the seed value

    • setSeed

      void setSeed​(long seed)
      Deprecated.
      Sets the seed of the underlying random number generator using a long seed.

      Sequences of values generated starting with the same seeds should be identical.

      Parameters:
      seed - the seed value

    • nextBytes

      void nextBytes​(byte[] bytes)
      Deprecated.
      Generates random bytes and places them into a user-supplied byte array. The number of random bytes produced is equal to the length of the byte array.
      Parameters:
      bytes - the non-null byte array in which to put the random bytes

    • nextInt

      int nextInt()
      Deprecated.
      Returns the next pseudorandom, uniformly distributed int value from this random number generator's sequence. All 232 possible int values should be produced with (approximately) equal probability.
      Returns:
      the next pseudorandom, uniformly distributed int value from this random number generator's sequence

    • nextInt

      int nextInt​(int n)
      Deprecated.
      Returns a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive), drawn from this random number generator's sequence.
      Parameters:
      n - the bound on the random number to be returned. Must be positive.
      Returns:
      a pseudorandom, uniformly distributed int value between 0 (inclusive) and n (exclusive).
      Throws:
      java.lang.IllegalArgumentException - if n is not positive.

    • nextLong

      long nextLong()
      Deprecated.
      Returns the next pseudorandom, uniformly distributed long value from this random number generator's sequence. All 264 possible long values should be produced with (approximately) equal probability.
