This question already has an answer here:

What are bitwise shift (bit-shift) operators and how do they work? 8 answers

>>> is the unsigned right shift operator. Since a is 60 and 60 is 111100 in binary, when you shift right twice you get 1111 which is 15.

>>> is the logical (or unsigned) right shift operator.

lets x= 10000000 00000000 00000000 01100000

x >>> 4 then x = 00001000 00000000 00000000 00000110

you can see the rightmost sign bit is also getting shifted to wards right but this is not true for >> .

if x = 00000000 00000000 00000000 00111100 ie x = 60

now x>>>2 so x = 00000000 00000000 00000000 001111 which is x = 15 .
