Returns the index of the nearest bit that is set to true that occurs on or before the specified starting index.

Usage

From source file:Main.java

public static void main(String[] args) {

    BitSet bitset1 = new BitSet(8);

    // assign values to bitset1
    bitset1.set(0);//from w  w  w  .java2  s  . c  om
    bitset1.set(1);
    bitset1.set(2);

    // print the sets

    BitSet bitSet = new BitSet();
    long[] array = { 1, 2, 3 };
    bitSet = BitSet.valueOf(array);
    System.out.println(bitSet);//from  w w  w.  j a  v a 2  s  .  com

    long[] tmp = bitSet.toLongArray();
    for (long number : tmp) {
        System.out.println(number);
    }

    System.out.println(bitSet.previousSetBit(1));
