# BitSet String toString() Method Example Program

Returns a string representation of this bit set. For every index for which this BitSet contains a bit in the set state, the decimal representation of that index is included in the result. Such indices are listed in order from lowest to highest, separated by ", " (a comma and a space) and surrounded by braces, resulting in the usual mathematical notation for a set of integers.

#### Program

```package com.candidjava;

import java.util.BitSet;

/**

* @description :The java.util.BitSet.toString() method Returns a string

*              BitSet contains a bit in the set state, the decimal
*              representation of that index is included in the result.

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

BitSet bitset1 = new BitSet(8);
BitSet bitset2 = new BitSet(8);

bitset1.set(0);
bitset1.set(1);
bitset1.set(2);
bitset1.set(3);
bitset1.set(4);
bitset1.set(5);

bitset2.set(2);
bitset2.set(4);
bitset2.set(6);
bitset2.set(8);
bitset2.set(10);

System.out.println("Bitset1:" + bitset1);
System.out.println("Bitset2:" + bitset2);

System.out.println("" + bitset1.toString());
System.out.println("" + bitset2.toString());
}
}
```

#### Output

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

#### Explanation

public String toString()
Returns a string representation of this bit set. For every index for which this BitSet contains a bit in the set state, the decimal representation of that index is included in the result. Such indices are listed in order from lowest to highest, separated by ", " (a comma and a space) and surrounded by braces, resulting in the usual mathematical notation for a set of integers.
Example:

BitSet drPepper = new BitSet();
Now drPepper.toString() returns "{}".
drPepper.set(2);
Now drPepper.toString() returns "{2}".
drPepper.set(4);
drPepper.set(10);
Now drPepper.toString() returns "{2, 4, 10}".
Overrides:
toString in class Object
Returns:
a string representation of this bit set
