WebMay 13, 2024 · Based on your comment, check out this simple test for holding one large value in a BitSet. BitSet bitSet = new BitSet (); bitSet.set (Integer.MAX_VALUE); long [] backingArray = bitSet.toLongArray (); System.out.printf ("Size of backing array = %,d longs.%n",backingArray.length); Prints Size of backing array = 33,554,432 longs. Share … WebSep 4, 2009 · You could be writing any objects out to an ObjectOutputStream, so the stream holds information about the types written as well as the data needed to reconstitute the object.. If you know that the stream will always contain a BitSet, don't use an ObjectOutputStream - and if space is a premium, then convert the BitSet to a set of …

WebOct 11, 2024 · Is there any better way to shift a bitset (by shifting I mean both left and right shift) When I convert a bitset with number of bits greater than 64, into long array, I get negatives in the array. Why is there a function toLongArray () in the first place when BitSet can only represent bits of 1 number. Please correct me if I am wrong. WebJan 13, 2024 · One way is to use BitSet to set the bits that represent the code as you compute it. Then you can do either BitSet.toByteArray () or BitSet.toLongArray () and write out the information. Both of these store the bits in little endian encoding.

WebAug 2, 2015 · If you're going to use each BitSet several times, it could be worthwhile to create a long array corresponding to each BitSet.For each BitSet:. long[] longs = bitset.toLongArray(); Then you can use the following method, which avoids the overhead of creating a cloned BitSet. (This assumes that both arrays are the same length). Webjava.util.BitSet.toLongArray()是BitSet类的内置方法,用于生成一个新的长数组,其中包含现有BitSet的所有位。根据官方文档,此过程以以下方式工作: north barnstead nh
