Java.util.BitSet.get() in Java
  • Last Updated : 16 Aug, 2018

There are two variants of get() in Bitset, both are discussed in this article.

1. boolean get( int value ) : Returns true if the value is present in Bitset, else returns false.

Declaration : 
public boolean get(int value)
Parameters : 
value : The value to check.
Return Value : 
Returns boolean true, if element present else returns false.




// Java code to demonstrate the
// working of get() in Bitset
  
import java.util.*;
  
public class BitGet1 {
  
public static void main(String[] args)
    {
  
        // declaring bitset
        BitSet bset = new BitSet(5);
  
        // adding values using set()
        bset.set(0);
        bset.set(1);
        bset.set(2);
        bset.set(4);
  
        // checking if 3 is in BitSet
        System.out.println("Does 3 exist in Bitset? : " + bset.get(3));
  
        // checking if 4 is in BitSet
        System.out.println("Does 4 exist in Bitset? : " + bset.get(4));
    }
}

Output :

Does 3 exist in Bitset? : false
Does 4 exist in Bitset? : true

2. Bitset get(int fromval, int toval) : method returns a new BitSet composed of elements present in Bitset from fromvale (inclusive) to toval (exclusive).

Declaration : 
public BitSet get(int fromval, int toval)
Parameters : 

fromval :  first value to include.
toval : last value to include(ex).

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




// Java code to demonstrate the
// working of get(int fromval, int toval)
// in Bitset
  
import java.util.*;
  
public class BitGet2 {
  
public static void main(String[] args)
    {
  
        // declaring bitset
        BitSet bset = new BitSet(5);
  
        // adding values using set()
        bset.set(0);
        bset.set(1);
        bset.set(2);
        bset.set(3);
  
        // Printing values in range 0-2
        System.out.println("Values in BitSet from 0-2 are : " + bset.get(0, 3));
    }
}

Output:

Values in BitSet from 0-2 are : {0, 1, 2}
