Thank you Harry bhai
Sir aap php Kai login or handling ka source code dalenge to acha hoga sir please reply and amazing java types
Brilliant 👍🏻
Great sir
THIS PERSON IS MORE IMPORTANT THAN ELON MUSK.
@Attitude girl shivangi your new song with Inder Chahal is great
True
Please don't compare elon

lol no
He is literally putting his most efforts. He deserves billions.
Not billions ... There are other tutors who are much better than him
Programmer 404 There may be but never compare. He is providing notes which he wrote himself. He is providing you with the cheat sheet. He writes everything he explained in his website. He is bringing a full course. Most importantly he explains in such an easy way. Now tell me do others provide you all this for free. I think that they don’t even provide such a valuable material after taking money too.

total space it occupies : n bytes
total bits it can hold : n*8 bits

For n bytes, range will be from ((2^(8n))/2) to ((2 ^(8n))/2) - 1

18:20 The formula for calculating the value range of a data type of n bytes is :-
Let n'=n*8
-2^(n'-1) to 2^(n'-1)-1
When its 2^(n-1) then y for byte its 128 . Coz 2^8 is 256. Bt the range of byte is 2^7. Can u pls clear ths doubt. Im a beginner.
Thank you
@@ApexFr777 see its easy
1 byte =8 bits(n)
and the formula is 2^(n-1)[n is the number of bits]

For n bytes

Thank you sir
For this playlist ❤❤❤
If a data type takes "n" bytes:
n bytes= 8 * n bits
range= -(2^8n)/2 to (2^8n/2) - 1
So, range= - 2^ (8n-1) to [2^ (8n-1)] - 1
18:10 Formula: -(2^(n*8))/2 to (2^(n*8))/2-1
Correct
@@rohans3447 Thanks 🤟🤟🤟
Same Answer No Difference
My answer is also same no difference 😅
A bit of modifications -
[-(2^(n*8))/2] to {[(2^(n*8))/2]-1}
Might look a bit complex XD, but it is mathematically correct.
I was thinking to take computer classes but after watching your videos I changed my thoughts. I don't know anything about computer but the way you are teaching is commendable. It is easy to understand.
I want to ask a question that "is this playlist contain complete java's topic? "
exercise done
public class Main {
public static void main(String[] args) {
int a = 5,b=8,c=9;
System.out.println(a+b+c);

I am from python programming, as I'm used to python syntax😅so the semicolon and int and other things make the syntax a bit harder, but Harry bhai explains it so well, it becomes really easy. Good job harry bhai.

Learn it, it's a very good thing especially with the increasing competition, but make sure that you are not overwhelmed by it.
If a data type take n byte then:
-(2^n*8/2) to (2^n*8/2)-1
Answer of your question 😉😉
If we take a data type like short.
short = 2 bytes.
2*8 = 16.
-(2^16/2) to (2^16/2)-1
Solution: -(-32,768) to (32,767).
It so easy thank you.... 😎😎
i already have a paid java course but still i m learning here more than paid course........
thanks for it...........Harry bhai🙂🙂
sorry to disturb u
but can u tell why we use int there like we could use long and it will still work
@@Ghostly_canvas Double and long use more space(memory). Also sometimes it's useful to make it clear that the value is an integer and will not have a decimal part.
For n bytes ,there would be "(n*8)"bits. So the value ranges from "- {2^(n*8)/2}" to {2^(n*8)/2}-1

Revising it once again so that my basic will be always strong. Repetition, Revision, Reiteration is the mother of learning. Thanks a lot Harry Bhai for this course.❣
Finally, completed the notes of this lectures, source code ,all concepts and others. Will complete the handwritten notes later as logic building and faster completion is more important than notes.

Java Statement Types.
Type of statements in java
In Java, there are several types of statements that can be used to perform different operations. Some of the most common types of statements in Java include:
Expression Statements: These statements are used to evaluate an expression and can include method calls, assignments, and other operations.
Declaration Statements: These statements are used to declare a new variable or constant and specify its type.
Control Flow Statements: These statements are used to control the flow of execution in a program, including if-else statements, switch statements, loops (for, while, do-while), and try-catch statements.
Jump Statements: These statements allow the program to jump to a specific part of the code, including break, continue, and return statements.
Assertion Statements: These statements are used to check assumptions made by the programmer and throw an error if the assertion fails.
Synchronized Statements: These statements are used to control access to shared resources in a multithreaded environment.
Labeled Statements: These statements are used to provide a label to a block of code, which can be used for easy navigation and readability.
Block Statements: These statements are used to group a set of statements together, which can be treated as a single unit for control flow or variable scoping.
You're a great teacher. Thanks for uploading these videos and putting up so much effort. Love your work. Great JAVA code!
