Constructor Details

ConcurrentBitSet

public ConcurrentBitSet()

ConcurrentBitSet

public ConcurrentBitSet(int nbits)

Creates a bit set whose initial size is large enough to explicitly represent bits with indices in the range 0 through nbits-1. All bits are initially false.

Parameters:

nbits - the initial size of the bit set

Throws:

NegativeArraySizeException - if the specified initial size is negative
