创建 BitSet 时是否可以设置位？

Question

我需要在循环中创建一些 BitSet，例如：

ArrayList<BitSet> bitSetList = new ArrayList<BitSet>();

for (int x : array) {
    bitsetList.add(new BitSet() //and set bits in specific places)
}

Answer 1

（要创建 BitSet 并设置特定位，）您可以使用以下之一：

• static BitSet valueOf(byte[] bytes) /** 
   Returns a new bit set containing all the bits in the given byte array.**/
  

• static BitSet valueOf(long[] longs) /**
   Returns a new bit set containing all the bits in the given long array.*//
  

• static BitSet valueOf(ByteBuffer bb) /**
   Returns a new bit set containing all the bits in the
   given byte buffer between its position and limit.**/
  

• static BitSet valueOf(LongBuffer lb) /**Returns a new bit set containing all the bits in the
   given long buffer between its position and limit.**/
