The java.math.BigInteger.not() method is used to find the bitwise-NOT of a BigInteger. This method returns a negative value if and only if this BigInteger is non-negative. The BigInteger.not() method apply bitwise Not operation upon the current bigInteger.
Syntax:
public BigInteger not()
Parameters: The method does not take any parameters.
Return Value: The method returns the bitwise-NOT value of a BigInteger with which it is used.
Examples:
Input: value = 2300 Output: -2301 Explanation: Binary of 2300 = 100011111100 NOT of 100011111100 in signed 2's complement is 1111011100000011 Decimal value = -2301. Input: value = 567689 Output: -567690
Below program illustrate the not() method of BigInteger():
/**Program Demonstrate not() method of BigInteger */import java.math.*;  public class GFG {      public static void main(String[] args)    {          // Creates BigInteger object        BigInteger biginteger = new BigInteger("2300");          // Call not() method to find ~this        BigInteger finalvalue = biginteger.not();        String result = "Result of NOT operation on " +         biginteger + " is " + finalvalue;          // Print result        System.out.println(result);    }} |
Output:
Result of NOT operation on 2300 is -2301
