Java BitSet - get() Method

The java.util.BitSet.get() method returns a new BitSet composed of bits from this BitSet from fromIndex (inclusive) to toIndex (exclusive).

Syntax

public BitSet get(int fromIndex, int toIndex)

Parameters

`fromIndex`	Specify the index of the first bit to include.
`toIndex`	Specify the index after the last bit to include.

Return Value

Returns a new BitSet from a range of this BitSet.

Exception

Throws IndexOutOfBoundsException, if fromIndex is negative, or toIndex is negative, or fromIndex is larger than toIndex.

Example:

In the example below, the java.util.BitSet.get() method returns a new BitSet composed of bits from the given BitSet.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a BitSet
    BitSet BSet = new BitSet();

    //populating BitSet
    for(int i = 0; i <= 20; i+=2)
      BSet.set(i);

    //printing BitSet
    System.out.println("BSet contains: " + BSet);

    //creating a new bitset from the above bitset
    BitSet newBSet = BSet.get(0,10);

    //printing BitSet
    System.out.println("newBSet contains: " + newBSet);
  }
}

The output of the above code will be:

BSet contains: {0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20}
newBSet contains: {0, 2, 4, 6, 8}
