Java BitSet length() method

The length() method of Java BitSet class returns the "logical size" of this BitSet. The length of BitSet goes up to the index of the highest set bit plus one. It returns zero if the BitSet does not contain any set bit.

Syntax:

Parameter:

Returns:

Exception:

Compatibility Version:

Java 1.2 and above

Example 1

import java.util.BitSet;

public class BitSetLengthExample1 {
	public static void main(String[] args) {
		BitSet bitset1 = new BitSet(5);
		BitSet bitset2 = new BitSet(5);
		BitSet bitset3 = new BitSet(5);
		
				
		bitset2.set(1);
		bitset2.set(2);
		bitset2.set(3);
		bitset2.set(4);
		
		bitset3.set(2);
		bitset3.set(4);
		bitset3.set(6);
		bitset3.set(8);
		bitset3.set(10);
		bitset3.set(12);
		
		System.out.println("bitset1: "+bitset1);
		System.out.println("bitset2: "+bitset2);
		System.out.println("bitset3: "+bitset3);
		
		int length1 = bitset1.length();
		int length2 = bitset2.length();
		int length2 = bitset3.length();	
		System.out.println("length of bitset1: "+length1);
		System.out.println("length of bitset2: "+length2);
		System.out.println("length of bitset3: "+length2);
	}
}

Output:

bitset1: {}
bitset2: {1, 2, 3, 4}
bitset3: {2, 4, 6, 8, 10, 12}
length of bitset1: 0
length of bitset2: 5
length of bitset3: 13
