I know that I can use ByteBuffer and BitSet to access the bits of the numbers but those are formatted into 2 bytes (16 bit). I assume I need to bitshift the values to access the ... WebOct 8, 2024 · A BitSet in Scala is implemented as an Array[Long], where each bit signals the presence of a number in the array.Long is 64 bit in Scala (on the JVM). One such Long can store values 0 to 63, the next one after it 64 to 127, on so on. This is possible since we're only talking about positive numbers and don't need to account for the sign. Given …
