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;

/**

public class BitSetStringToString {

		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
