In C/C++ there is only one right shift operator ‘>>’ which should be used only for positive integers or unsigned integers. Use of right shift operator for negative numbers is not recommended in C/C++, and when used for negative numbers, output is compiler dependent (See this). Unlike C++, Java supports following two right shift operators.
1) >> (Signed right shift) In Java, the operator ‘>>’ is signed right shift operator. All integers are signed in Java, and it is fine to use >> for negative numbers. The operator ‘>>’ uses the sign bit (left most bit) to fill the trailing positions after shift. If the number is negative, then 1 is used as a filler and if the number is positive, then 0 is used as a filler. For example, if binary representation of number is 10….100, then right shifting it by 2 using >> will make it 11…….1.
See following Java programs as example ‘>>’
2) >>> (Unsigned right shift) In Java, the operator ‘>>>’ is unsigned right shift operator. It always fills 0 irrespective of the sign of the number.
