4.7 Left and Right Shift Operator in Java

The left shift operator shifts a bit pattern to the left, and the right shift operator shifts a bit pattern to the right. The bit pattern is given by the left-hand operand, and the number of positions to shift by the right-hand operand. The unsigned right shift operator shifts a zero into the leftmost position.

Also Just for info : The left-shift by 1 and right-shift by 1 are equivalent to multiplication and division by 2 respectively

[@tech100sec]

Thank you for this video. I never understand these terms in programming, but you described these terms in simple language and I can easily understand these terms from now.

[@tanveersayyed561]

you are great sir i have so many basic doubt in java i got demotivated when i see your videos i restored my Confidence

easy to understand, thanks for this sir 👍👍

[@Yuka_1990]

Thanks for the Video. I had trouble to understand this Operation in my Workbook.
Good Work :)
This Operations are faster than the arithmetic division and multiplication Operators.
In time critical processes this can save time.

[@TheGamerGuy201]

Great video...I was struggling to find the next power of 2 while implementing segment trees..

[@lionciomorcilla4743]

Right shift filled with zero ?

[@sharukhbilal9001]

Wow nice expanation I got cleared with this doubt

[@abrehamish]

It would be great if you could include unisgned and signed shift operators

[@shakeebarsalan970]

i like this video bcoz this is very short and easy

[@shivanineharkar2571]

really helpful thanks

[@ArkoSarkar1]

So shortcut is in left shift add specified number of zeros at the end, in right shift remove the specified number of zeros and ones at the end?

[@aromaljayachandran4300]

Thanks a lot brother

[@architsharma6068]

Thanks a lot, Sir

[@shakiraafshan6544]

where do we use left shift and right shift operators?

[@TheGamerGuy201]

Bit manipulation
A good example to get started is that if you are given a number,then find the next greater number which can be written in the power of 2.
Example-If you are given 5, then you should return 8(2^3).
The above mentioned program is also useful when trying to implement advanced data structures like Segment trees.That's what got me here :P

[@slizora5704]

Thank you :)

[@RajkamalKamal-bh9jq]

So Right shift ->it loose last 2digit
Left shift ->it will add 2 zero in the last

[@coding_ss632]

Thanks a lot.

Difference between Right shift and Unsigned right shift in Java ( >> and >>> )
?

[@viorelpaluta3815]

thanks bro

[@nishanksoni7120]

int num = 5;
// Left shift :
int b1 = num >> 1; // 2 ^ 1 = 2 , 5 /2 = 2
int b2 = num >> 2; // 2 ^ 2 = 4 , 5 / 4 = 1
int b3 = num >> 3; // 2 ^ 3 = 8 . 5 / 8 = 0
System.out.println(b1 + " " + b2 + " " + b3); // 2 1 0
// Right shift :
int c1 = num

Whats realtime application for shift operators?

[@mohammednumanahmed3163]

love uuuuuuuuuuuuuu bhai

[@asta5583]

Thank yu

[@malaak1h]

what is the use of the left right shift operator?

[@user-jr6zr9rc2w]

Pls help
Int a=64
Byte b=(byte) (a

[@mettagowtham9768]

If we left shift by 2 bits it's value become from 64 to 256 and
And you are trying to get this output in the byte type. The byte can only store value from -128 to 127.
So the output has one error

[@159saur]

Can you please explain unsigned right shift as well ?

[@semplex9992]

i love you

[@kuldeepruletiya3146]

sir what is difference between >> and >>> ?
when i will use it?
i am getting different output
2>>5 gives 0
-2>>>5 gives 134217727
-2>>5 gives -1
and
2>>>5 give 0
?
why ?

[@aronblanche]

>> is signed right shift, >>> is unsigned right shift...i.e. >>> fills up 2's complement form of the number from right side

[@blurmn9466]

thanks, finally i found a good explanation

[@shivanisoni5935]

Sir differen between >> $ >>>.
Please tell...

[@sachinkataria6667]

Sir what if the variable type is float in this example

[@-arun-3397]

Why should we use this shift operator in java ? Tell me real life example for this ..

it is use full

How are you remember this all decimal numbers binary form ?

can you explain this ">>>"

[@nikeshacharya8655]

3 bits right shift

[@alopradocai]

I find it baffling that every time I search for something about computer programming, I always end-up on a tutorial by someone with an Indian accent.

[@ranveervaghela7030]

One day Indians will rule the world 🌎

[@jvjplus]

What's the difference between >> and >>>

[@screwedidiot937]

>> (right shift)
Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand.
Ex: i=8; //1000 in binary
i >> 2; // gives 10 in binary
>>> (zero fill right shift)
Shift right zero fill operator. The left operands value is moved right by the number of bits specified by the right operand and shifted values are filled up with zeros.
Ex: i =8; //1000 in binary
i >>> 2; // this gives 0010 in binary

how to convert numbers to boolean

[@AbhiShek-nv3vq]

Great

[@mk9834]

wow i dont know this exists!

[@sandeepsahu8743]

Sir...But why left shift will add bits to it and right shift will loose 2 bits?? Why the left shift not loosing 2 bits from left side?

[@maff1917]

Because you shift from right to left

[@zeeshantunio3390]

make simple program we can understand just debit credit addition multiplication making of atm matrix u can make that is hard program u have made but saving that video

[@smile-me2ik]

Coz We perform any operation on binary from left..... Moreover no. Has to be shift left..... So wont u apply force from right😉

[@Matilda32664]

Interesting, but could anyone tell me when and where are those useful? I've been programming for some time and never had to use this operators

[@dhritiayusj2710]

Because we don't think about memory level optimization.
For ex. We can double & half a number just by shifting one bit, whereas we will use traditional approach by multiplying or adding

[@BoredStory]

@@dhritiayusj2710 yeah it applies on games and high specs softwares

oh left shiftt will add 0 and right will remove.come on bhai agar sahi se nhi aata to pahle knowledge lo phir video banana.theek hai
