I used to use the >> operator for right shifting. Now I've just replaced it with >>> and found the same result. So I can't figure out whether these two are fundamentally equal or not.

The >> operator is a signed right shift operator and >>> is an unsigned right shift operator. The left operands value is moved right by the number of bits specified by the right operand.
&& is used to perform and operation means if anyone of the expression/condition evaluates to false whole thing is false. || is used to perform or operation if anyone of the expression/condition evaluates to true whole thing becomes true. so it continues till the end to check atleast one condition to become true.
It is a binary AND Operator and copies a bit to the result if it exists in both operands. (A & B) will give 12 which is 0000 1100. Whereas && is a logical AND operator and operates on boolean operands. If both the operands are true, then the condition becomes true otherwise it is false.
>> is arithmetic (signed) right-shift, >>> is logical (unsigned) right-shift, as described in the Java tutorial. Try them on a negative value, and you will see a difference.

The first operator sign-extends the value, shifting in a copy of the sign bit; the second one always shifts in a zero.
The reason for this is to emulate unsigned integers for the purpose of doing bit operations, partially compensating for the lack of unsigned integral types in Java.
