Java.util.BitSet.get() Method

Description

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

Declaration

Following is the declaration for java.util.BitSet.get() method

public BitSet get(int fromIndex,int toIndex)

Parameters

• fromIndex − index of the first bit to include.

• toIndex − index after the last bit to include.

Return Value

This method returns a new BitSet from a range of this BitSet.

Exception

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

Example

The following example shows the usage of java.util.BitSet.get() method.

package com.tutorialspoint;

import java.util.*;

public class BitSetDemo {
   public static void main(String[] args) {

      // create 2 bitsets
      BitSet bitset1 = new BitSet(8);
      BitSet bitset2 = new BitSet(8);

      // assign values to bitset1
      bitset1.set(0);
      bitset1.set(1);
      bitset1.set(2);
      bitset1.set(3);
      bitset1.set(4);
      bitset1.set(5);

      // assign values to bitset2
      bitset2.set(2);
      bitset2.set(4);
      bitset2.set(6);
      bitset2.set(8);
      bitset2.set(10);

      // print the sets
      System.out.println("Bitset1:" + bitset1);
      System.out.println("Bitset2:" + bitset2);

      // get index 1 to 4 of bitset1
      System.out.println("" + bitset1.get(1,4));

      // get index 2 to 10 of bitset2
      System.out.println("" + bitset2.get(2,10));
   }
}

Let us compile and run the above program, this will produce the following result −

Bitset1:{0, 1, 2, 3, 4, 5}
Bitset2:{2, 4, 6, 8, 10}
{0, 1, 2}
{0, 2, 4, 6}
