The boolean operators include relational operators and logical operators. Only boolean expressions can be used in control flow statements and as the first operand of the conditional operator ?:. An integral value x can be converted to a value of type boolean, following the C language convention that any nonzero value is true, by the expression x!=0. 
An object reference obj can be converted to a value of type boolean, following the C language convention that any reference other than null is true, by the expression obj!=null.

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

// these are boolean variables     
      boolean A = true;
      boolean B = false; 

      System.out.println("A|B = "+(A|B));
      System.out.println("A&B = "+(A&B));
      System.out.println("!A = "+(!A));
      System.out.println("A^B = "+(A^B));
      System.out.println("(A|B)&A = "+((A|B)&A));
