Using the Bitwise Logical Operators

public class Main {
  public static void main(String args[]) {
    int a = 1;
    int b = 2;
    int c = a | b;
    int d = a & b;
    int e = a ^ b;
    int f = (~a & b) | (a & ~b);
    int g = ~a & 0x0f;

    System.out.println(" a = " + a);
    System.out.println(" b = " + b);
    System.out.println(" a|b = " + c);
    System.out.println(" a&b = " + d);
    System.out.println(" a^b = " + e);
    System.out.println("~a&b|a&~b = " + f);
    System.out.println(" ~a = " + g);

  }
