i do hope your channel have everything about java, coz i was a failure back in college, i took computer science as my degree, and now, i want to redeem myself in life. thank you soooo much for this by the way
I just went and bought your bootcamp, John. Wow, you really have a knack for making this easier and more enjoyable. Thank you, I was worried about passing the college course I am currently taking; I'm not worried any more. In fact, I just ran a practice test I had gotten in the 60s three times prior and this time got a 77%. Thank you so much!
Great video John! I've been watching a whole bunch of your tutorials as I aspire to become a Java backend engineer, and they've been really helpful! About chars, I found them to be a lot useful when looping through strings in "for each" statements, do you know a better way to do so? Thanks again for the great content!
So this doesn't exactly answer your question, but one interesting use of looping with chars is when you need to do something alphabetically, like this example from a chess program: private static Stream generateAllSquares() { final List squares = new ArrayList(); for (char file = 'a'; file
I came back to this video because I just watched a video of a guy doing a 6 billion point combo in Tony Hawk Pro Skater 4. When the game finally tallied it up, it didn't get past 1.6 billion even though the combo did, in fact, add up to 6 billion. So the programmers must have used int instead of long. If only they could have foreseen the jump in human evolution from 2003 to now. No one was capable of such things back then.
Char is also a whole number data type and stores the ascii value, so you can do calculations with it. That comes in handy lots of times where I work ^^
I have been traveling on Earth with Java for 10 years just 5 miles, but after watching your approx 10:23 minutes tutorials I have traveled with java 24,887.64 miles which is exactly the circumference of the Earth. Thank you soo much for making everything too easy to understand.
I am taking a web design class and in my assessment I have to have 2 char's in a row. The first char works. But I can't seem to get the second char to work correctly? What am I doing wrong?
I don't understand how a programmer decides which type to use. Should I just primarily use int? If I use int for a small amount of data am I misusing the type?
Do you mean, if you use a Scanner to read the user input and decide if they type 'true' or 'false' ? A little example I made of that scenario here just using the Main class for simplicity's sake (you have to import the scanner for this to work): ----------------------------------------------------------------------------------------------------------------------------------------------------------------- package (name of your package) import java.util.Scanner; public class Main{ public static void main(String[] args){ checkForUserInputWithBoolean(); } public static void checkForUserInputWithBoolean() { Scanner scanner = new Scanner(System.in); System.out.println("Are you a human? Answer 'true or false' "); byte checker = 0; while (checker == 0) { try { boolean userAnswer = scanner.nextBoolean(); if (userAnswer == true) { System.out.println("You are a human being"); checker = 2; } else if (userAnswer == false) { System.out.println("You are not a human being "); checker = 1; checkForUserInputWithBoolean(); } else{ checker = 0; } } catch (Exception e) { System.out.println("Wrong input, must be true or false "); checker = 1; checkForUserInputWithBoolean(); } } } }
Interesting, thanks Nathan! I haven't used Scratch yet but I've heard a lot about it, I'll see if I can learn something about it and see if there's a boolean equivalent in Scratch.
@@CodingWithJohn Hey John. Thanks for the response. Nathan was excited when I told him "Hey John replied" :-) Btw I watch your videos. Love the way you explain. Great pronunciation, intonation, clarity and no unnecessary details. Waiting for more .. :-)
Watching this in comp class is a truly blissful thing thanks for making these videos

JUST STARTED TO STUDY JAVA AND YOU EXPLAIN REALLY GOOD

I'm so glad it's helpful, thank you! I just added a set of lessons on the Collections framework last night, and always working on more!
You are awesome! I loved this tutorial and now I am clear with this topic. Please keep going. You have a new subscriber.
THANK YOU BROTHER, YOU TEACH BETTER THAN MOST PROFESSORS GOD BLESS YOU
thank you so much my java teacher is the worst teacher ever but thanks to you I can actually learn. Big help
Best explanations i've found. Thanks!
Thanks for taking your time to explain primitive data types.
Omg you explain this so much better than my professors! Thank you!
very dedicated and mature content for me. love this. thanks for your time and dedication.

Why is it always the short videos that helps more than an hour video
Absolute gold explanation

Very easy to understand,Great jobbb
Thanks a lot, your video is so explanatory 🙏✨
Good explanation Mr. John. Actually I want to know about "how to handle primitive data types in java? " Please explain it .✨
Thank you for the lesson 😁
will make sure watch ur vid every week
keep it up

Well appreciated appreciation comment
Incredible, thanks for doing this
Thank you Bro! Its easy to follow
Love from India
An incredible video from John
I like your videos. Thanks John!
Thanks, John, your videos are awesome!
i like that kramer painting in the back. and also the video.
Personally I feel lower case L is 'wrong' solely because at a glance it could be easily mistaken for a 1. I think Upper case is clearer.
May God bless you and your family.
You nailed it ❤❤
Thank you sir.
the byte type is pretty useful to handle binary data byte by byte
Great video but I would like 1.5 or 2 times slower :) - But very good explained
Thank you for the help
Do you have any videos that talk about non-primitive data types?
i like your style
wow. brilliant

thank you thank you
I don't understand how a programmer decides which type to use. Should I just primarily use int? If I use int for a small amount of data am I misusing the type?
no. but if your number exceeds 2 billion you need to use a long. people dont just always use long bc it takes more time to run.
If we want to store larger value than long data type( > 9,223,372,036,854,775,807) then , how we can store it ?
Check out BigInteger: docs.oracle.com/javase/7/docs/api/java/math/BigInteger.html
Wonderful
if I were to use "boolean" is there a way to have the "user" input "TRUE or FALSE" when I run the program for the variable?
Do you mean, if you use a Scanner to read the user input and decide if they type 'true' or 'false' ?
A little example I made of that scenario here just using the Main class for simplicity's sake (you have to import the scanner for this to work):
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
package (name of your package)
import java.util.Scanner;
public class Main{
public static void main(String[] args){
checkForUserInputWithBoolean();
}
public static void checkForUserInputWithBoolean() {
Scanner scanner = new Scanner(System.in);
System.out.println("Are you a human? Answer 'true or false' ");
byte checker = 0;
while (checker == 0) {
try {
boolean userAnswer = scanner.nextBoolean();
if (userAnswer == true) {
System.out.println("You are a human being");
checker = 2;
}
else if (userAnswer == false) {
System.out.println("You are not a human being
");
checker = 1;
checkForUserInputWithBoolean();
}
else{
checker = 0;
}
}
catch (Exception e) {
System.out.println("Wrong input, must be true or false
");
checker = 1;
checkForUserInputWithBoolean();
}
}
}
}
Do you have discord group to java studies ?
is there any video that ı can find class as data type? ı mean you create public person mother inside the person class and ı dont understand
thankssss
I prefer capital 'L' for longs, l looks too much like 1 in certain fonts (like yours :))
Using lowercase L is evil, considering 1 and lowercase L look the exact same
Can i do this on Android using java N-IDE?
You guys call it "char" but when it is character, you call it is as "karacter". May i know the logic behind this 🤦
Char is an actual word. It's the black stuff when you burn something. Char is pretty unique because most words that start with 'cha' has a 'k' sound.
not logic just a intricacy of the English language
@@timbo2legit2quit like a charred marshmallow for example
My son Nathan asked me to comment here. He is saying that boolean data type is not there in Scratch coding language.
Interesting, thanks Nathan! I haven't used Scratch yet but I've heard a lot about it, I'll see if I can learn something about it and see if there's a boolean equivalent in Scratch.

annotations in java
I disagree about memory. As java is yet considered to be a language for mobile, development memory is still a valuable resource in that context.
You might want to have done this in your first 10 videos, and not around the 40th.
it's million billion trillion quadrillion quintillion sextillion septillion octillion etc
but i need a jillion datatype
Hmmmmmm try BigInteger. Not a primitive, but essentially only limited to the amount of memory you have.
I am cool i call it char. Are you cool?
10lbs of... do I actually know what tho ? ;)
My bank account is measured in byte.
