BitSet Class toString() method

• toString() method is available in java.util package.
• toString() method is used to represent string denotation of this BitSet so the representation would be from the first index to the last index separated by ',' or whitespace "" and surrounded by curly braces {}.
• toString() method is a non-static method, so it is accessible with the class object and if we try to access the method with the class name then we will get an error.
• toString() method does not throw an exception at the time of string representation of this BitSet.

Syntax:

    public String toString();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of this method is String, it returns string representation of this BitSet.

Example:

// Java program to demonstrate the example 
// of String toString() method of BitSet.

import java.util.*;

public class ToStringOfBitSet {
    public static void main(String[] args) {
        // create an object of BitSet
        BitSet bs = new BitSet(10);

        // By using set() method is to set
        // the values in BitSet 
        bs.set(10);
        bs.set(20);
        bs.set(30);
        bs.set(40);
        bs.set(50);

        // Display Bitset
        System.out.println("bs: " + bs);

        // By using toString() method is to 
        // string representation of this BitSet
        String s = bs.toString();

        // Display s
        System.out.println("bs.toString(): " + s);
    }
}

Output

bs: {10, 20, 30, 40, 50}
bs.toString(): {10, 20, 30, 40, 50}
