How to perform logical andNot operation on BitSet in Java ?
Declaration :
|
1 |
public void andNot(BitSet set) |
Explanation :
| Purpose | The andNot(BitSet set) method clears all of the bits in this BitSet whose corresponding bit is set in the specified BitSet. |
| Parameters | set ===> the BitSet with which to mask this BitSet. |
| Return Value | This method does not return a value. |
| Exception | NA |
Java Program : Example
Below example will explain java.util.BitSet.andNot() method.

Value of Bitset Obj 1 : {10, 11, 12, 13, 14, 15} Value of Bitset Obj 2 : {10, 12, 14, 16, 18} andNot Result : {11, 13, 15} |
