public class Random extends Object
Constructor and Description 

Random()
Creates a new random number generator.

Random(long seed)
Creates a new random number generator using a single long seed: public Random(long seed) { setSeed(seed); } Used by method next to hold the state of the pseudorandom number generator.

Modifier and Type  Method and Description 

protected int 
next(int bits)
Generates the next pseudorandom number.

boolean 
nextBoolean() 
void 
nextBytes(byte[] bytes) 
double 
nextDouble()
Returns the next pseudorandom, uniformly distributed double value between 0.0 and 1.0 from this random number generator's sequence.

float 
nextFloat()
Returns the next pseudorandom, uniformly distributed float value between 0.0 and 1.0 from this random number generator's sequence.

int 
nextInt()
Returns the next pseudorandom, uniformly distributed int value from this random number generator's sequence.

int 
nextInt(int n)
Returns a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive), drawn from this random number generator's sequence.

long 
nextLong()
Returns the next pseudorandom, uniformly distributed long value from this random number generator's sequence.

void 
setSeed(long seed)
Sets the seed of this random number generator using a single long seed.
