Shift Operator Summary : Bitwise Operators « Operators « SCJP






  1. SCJP
  2. Operators
  3. Bitwise Operators
The shift operators, >>, >>>, and << work with integer primitives only; 
The >> right shift extends the sign so a negative number stays negative
The >>> operator shifts in zero bits, creating a positive number. 
The << left shift always shifts in zero bits at the least significant position.


Operator        Example         Result
  
<<              3 << 2          12
   

>>              -6 >> 2         -2
   

>>>             -6 >>> 2        1073741822

        System.out.println(-6 >>> 2);
