5.18 Swapping of Two Numbers in Java in 3 Different ways

Swapping of Two numbers with 3 different Logics
1. Using Temp
2. Without using Temp variable
3. XOR
In this video we will see how to interchange the values of 2 variable. That means if there are 2 variables a = 5 & b = 4 after swapping the value of a = 4 & b= 5

[@SmartProgramming]

nice one sir, third way is new for us, thanks and keep it up 👍👍

[@arghadeep6363]

Thanks for the programs

[@srikanthchilamkuri8069]

3rd method is super sir..

[@milind006]

Unless you’re using a specialised compiler which compiles for a specific system which has some very critical memory limitations, an Internet declaration will simply assign 32 bits (4 bytes) for an int. So whether you need 3 or 4 bits is immaterial and the full 32 bits will be used for an integer anyway. Memory isn’t assigned by bits, but by words. So even if a data type requires only 1 byte, if the default word size of an OS is 4 bytes, 4 bytes will be used even for such a data type because the performance benefits of using a fixed word size outweigh the memory benefits of saving a bit. Furthermore, it is always useful to have code which is clear to understand when you consider maintenance, and from the perspective, the first method is the easiest to understand, and would be preferred in a professional setting

[@shuvshaw9594]

very helpful

[@uss3ewa]

thx for xor search for this around 15 min

[@user-qg9nd5jv8s]

Bravo!

[@iVodkaBeerMaikMB]

thanx man

[@muftinowsheen3597]

Sir how to swap 3 numbers in java?

[@pavuk7086]

Спасибо мужик!!!

[@tonpenarayana7507]

awesome

[@kalyanroy6687]

Its wrong to ask this here,but still i wanna ask u,, Can you please make tutorials on Data Structures and Algorithms?

[@mohammedviso2269]

Thank you a lot.....

[@miguelconstantino-guzman7957]

Does anyone know how to swap two numbers given a Number class? It is an object that the reading did not cover. I am given a static swap method with two Number objects as parameters, no return type, and two Number objects in the main method, each initialized with two user-int inputs. The swap method in main is: swap(num1, num2) and passed to the static method swap(Number num1, Number num2) { ... }. Also: the Number class contains a setter and getter method with a constructor, public Number(int n) { num = n; } where num is a private member field.

[@meenakshitomar2943]

why are we passing (string[] args) as a parameter to main func? can u please answer?

[@meenakshitomar2943]

Thankyou... sir

[@ito6787]

My four key is swapped with the numbers 2 and 3 being pressed once very quickly, can someone comment a step by step on how to fix it?

[@sandeepreddy7716]

how is possible when four byte = three bytes example a=9 and b=4 by using xor

[@Gtvteluguindia]

possible

[@023PrashantSharma]

let a=9=1001 b=4=100 we can also write.. 1001 0100 ```````` a=a^b//1000^0100==1101=13 b=a^b//1101^0100==1001=9 a=a^b//1101^1001==0100=4 a=4 b=9 so easy if u have knowledge of boolean algebra..

[@manoharreddy4988]

Why can't we just assign the number value alphabets in system.out.println

[@xReema]

❤️❤️❤️❤️🙏🏻🙏🏻🙏🏻🙏🏻

[@hemalathahema8976]

sir there is another way which is a=a*b; b= a/b; a= a/b.

[@duggirambabu7792]

It is applicable when a≠0 and b≠0.

[@Thegamer-yp7qq]

in OR 1 1 = 1 not 0 ?right?

[@suseelasusi2879]

It's XOR operation

[@duggirambabu7792]

0 OR 0 = 0 0 XOR 0 = 0 0 OR 1 = 0 0 XOR 1 = 1 1 OR 0 = 0 1 XOR 0 = 1 1 OR 1 = 1 1 XOR 1 = 0

[@Karansaini54777]

my friend send me mobile number but i cannot see these number hiding number in xxxxxxxx please give me solution to see

[@shuvshaw9594]

// using extra variables int x=100,y=200,extra; extra=x; x=y; y=extra; System.out.printf("X is now %d Y is now %d ",x,y);

[@shuvshaw9594]

//^ stands for XOR operation int x=100,y=200; x=x^y; y=x^y; x=x^y; System.out.printf("X=%d and Y=%d",x,y);

[@jatingandhi4286]

One more easy way a=a*b b=a/b a=a/b

[@milind006]

It fails if b is 0. Also, doesn’t translate well to char, or even float types especially if you want the program to be portable across OS

[@Juliodonadello]

doesn`t work with 0 and should be: a=a*b b=a/b a=a/b

[@prashanthkuntrapakam]

reddy rules

[@shuvshaw9594]

// using +,- operation int x=100,y=200; y=x+y; x=y-x; y=y-x; System.out.printf("X is now %d Y is now %d ",x,y);

[@milind006]

You’re mixing Java and C here.

[@shuvshaw9594]

@@milind006 Kindly tell how.

[@milind006]

​@@shuvshaw9594 You know what, turns out I was unaware of the existence of the System.out.printf method for printing to the standard output. There is nothing wrong with your code snippet. I learned something new :)
