Hey man, I'm going to be a sophomore in high school and I'm taking AP Computer science. We are using Blue J and Java just like this. I just wanted to let you know you are helping me a lot with this, I just wanted to get a head start over the summer and you're making it much easier on me
Tyler Hough I'm glad I could help you out. You'll find my series pretty similar to your course as I based it off my own experience going through AP Comp Sci. The only thing I don't really go into is Gridworld, just because it is annoying to teach and they are removing it from the curriculum within the next few years.
Hi MercifiesProductions!! Do you have a tutorial on bluej that asks for a certain name then count and display the vowels used in that certain name. If not can you pls make..thank you!! :D
BlueJ coding with JAVA is the best. I had to create a project using java and I couldn't figure it out using anything else but BlueJ. So :). Very user-friendly system.
I know the vid is like 7 yrs old but I just want to say that it was a good vid and your voice was good voice to listen to Thanks for the video it was very helpful
Salman Samie because importing java.util.* is for typing input into your program. This lesson doesn't do that, the program you make only outputs the helloworld statement. If you import something and don't use it, the compiler will throw you an error.
Nice tutorial. Thank you. You may want to edit a mistake you made. These { } are braces and not brackets. [ ] are brackets. Not a big deal but it prove confusing to some.
+Joseph Dukmak I can't reply to your comment, so I'm not sure if you'll see this. You have comment replies turned off. Post your code so I can look at it
MercifiesProductions This is the code i used: public class HelloWorld { public static void main(String[] args) { System.out.println("Hello World my name is Joseph."); } } but when i compile then i do the *void main(String[] args)* it gives me this: HelloWorld.main({ }) Hello World my name is Joseph.
With your Terminal open (where the code outputs), go to the menu bar and Click Options -> Clear Screen at Method Call. Make sure that is checked and it will fix your problem
when i compile it, it hi-lights the .out in system.out.println in red and says "package system does not exist" and will not let me go to "void main(String[] args)" please help my code is; public class HelloWorld { public static void main(String[] args) { system.out.println("Hello World my name is (think of one later)"); } }
Static means that the variable or method marked as such is available at the class level. In other words, you don't need to create an instance of the class to access it.
MercifiesProductions I figured it out, thanks, I am watching on a low quality monitor so I couldn’t see the symbols inside the quotation marks. I thought you were using * lol
its a keyword. Key words are the reserved words of java program with some special meaning and can be used for that purpose only. the keywords cannot be used as indentifiers that is, variable name, class name or method name. as java is a case sensitive language, keywords are must to be written in lowercase only. Even 'class' is also a keyword in java.
Im just starting for the first time and when I open bluej it asks me to select a suitable jdk but it says i do not have one even though I downloaded it. Hod do I make it work?
Hello, MercifiesProdcutions.. I am a beginner programmer, and I hope your tutorials help me out a lot. However, I noticed you didn't know what some things were called. WhenYouTypeLikeThis it's called CamelHump typing, and theres "" are called quotation marks.
Craig HurpinDurpin This video is from 2 years ago, so they get better in quality over time. I'm considering remaking the originals to up the content quality
it's for when you want to pass arguments to the main method, usually when running the program from a terminal, but you don't really have to worry about it too much for now.
As of right now it won't affect your program, but later on it may cause problems where the program believes it is an overrided constructor. It's good practice to put String[] args in there
Hard to understand you since you don't explain each item you are typing. They are called double apostrophes or quotations. Please increase the font size. This would make it so much easier to see the code.
+MercifiesProductions Ohh i just saw the Uni of Kent and thought whats that doing there on blue j. I study there so I was curious. I went on Wikipedia and it so happens my lecturer in the uni of kent is the one who created it!
Haha nice. Yeah, I started using bluej back in highschool for my comp sci classes. Now at college, and we still use bluej. Schools like it because there is no prompt when you are typing in code so it has to be done from memory, not from typing half the word then hitting enter twice
making mistakes like this is the best way to learn. If you don't realize immediately that you are making a stupid mistake, you will begin to think what possibly gone wrong looking for the most complicated solution. in this process you learn a lot.

When you run it and the compiler opens, click on Options>Clear Screen at Method Call.
Excellent video, keeps complicated computer jargon in context.
WOHO! THANKS MAN :D Gonna watch all your tutorials!
Couldn't you start with explaining what class, method and all the stuff are? This is really not understandable for begginer?
The weed is strong in this one... :)
Thank you for this!! Your videos are awesome!!!
You're an awesome teacher!!

Quinten Kock they both perform the same function, and now a days I use public static void main
I feel like I just watched a tutorial by Jim Breuer's character from Half-Baked. But I like it!

Here because of computer science class, I realize this video was made a long time ago but thanks
amazing tutorials
you can also write without using public,private,static,string[ ] args for normal programs.
when I clicked void main(String[] args) again, it produced another Hello World my name is Victor.. can I remove the other one?? how??
Nice tutorial. Thank you. You may want to edit a mistake you made. These { } are braces and not brackets. [ ] are brackets. Not a big deal but it prove confusing to some.
This is what i get when i try doing it:
HelloWorld.main({ })
Hello World my name is Joseph.
Any help about this ?
Legend man! Thanks
thank you it was really helpful
System.out.println(“Hello: “)
String World = scan.nextLine();
System.out.println(“Hello “ + World)
Big up the University of Kent, well weird one of my lectures helped create BlueJ
Anyone here from AP Comp Sci in highschool
yees
Me.
yes, because my teacher wont explain it. huzzah for Pandemic Zoom classes

I can't reply to your comment, so I'm not sure if you'll see this. You have comment replies turned off.
Post your code so I can look at it
MercifiesProductions
This is the code i used:
public class HelloWorld
{
public static void main(String[] args)
{
System.out.println("Hello World my name is Joseph.");
}
}
but when i compile then i do the *void main(String[] args)* it gives me this:
HelloWorld.main({ })
Hello World my name is Joseph.
Joseph Dukmak So it is actually posting the HelloWorld.main({ }) in the output when you compile it? That is strange, I'll keep looking into that
***** you're welcome :)
public static void main(String[] args) {
System.out.println("I really liked this video thank you xD");
}
lit homie
love this thank u
thank you so much.
Can BlueP be developed for Python to help students with Object Oriented concepts since python is used in Schools?
THANK YOU VERY MUCH
i use println and its giving an error that expected
i think you forgot to give a curly bracket after
void main()
{
can u send me link to #5
what does package not exist mean?

Hi when i tried to compile, i got an error (package System does not exist)
Please advise.
+Kast Dan you should write System.out.println instead of system.out.printin "capitalized S"
when i compile it, it hi-lights the .out in system.out.println in red and says "package system does not exist" and will not let me go to "void main(String[] args)" please help my code is;
public class HelloWorld
{
public static void main(String[] args) {
system.out.println("Hello World my name is (think of one later)");
}
}
All or Nothing gameplay ! never mind did not cap the S man im stupid
when I click on new class there is no applet option on my bluej please help!
yea I know am 2 years late and u would have already known by now but BlueJ was updated so yea u wont find that option now
I always use 'public static void main' instead of 'private static void main'. Don't know what one is better though.
Public is better
It is System.out.println()
S is captial letter
Yes it will be capital
What does the word "static" mean in
PUBLIC STATIC VOID MAIN()?
Static means that the variable or method marked as such is available at the class level. In other words, you don't need to create an instance of the class to access it.
Legend!
I took one look at the state of that desktop and decided to go elsewhere.
lol
My dashed arrow does not show up?
6:45 sir shouldn't it be public static void main??
yes you are right
very useful......
tysssm
Hi,Mercifies Production Could do a video in which you call a class using bluej, it would be very helpfull.
Thank you
ruclips.net/video/XznNdY3Bfvg/видео.html --> I don't use bluej in this tutorial but it works the same way.
Thank you so much for the video but at about 4:30 when your phone rang just killed me XD....
useful for me
For some reason it says illegal start of expression when I try to compile it, but I have the same thing as you
Post the full code and error
MercifiesProductions I figured it out, thanks, I am watching on a low quality monitor so I couldn’t see the symbols inside the quotation marks. I thought you were using * lol
What is public static void main??
?
The main method or also known as Function in other programming languages like C and C++... The Boss, so to say...
its a keyword.
Key words are the reserved words of java program with some special meaning and can be used for that purpose only. the keywords cannot be used as indentifiers that is, variable name, class name or method name. as java is a case sensitive language, keywords are must to be written in lowercase only. Even 'class' is also a keyword in java.
wow this really is caps sensitive got error for writing system with a small s
+Iphecle Kennedy Yeah it's a pain sometimes but you will get adjusted to it as you practice more
Get used to tat in Java
Im just starting for the first time and when I open bluej it asks me to select a suitable jdk but it says i do not have one even though I downloaded it. Hod do I make it work?
if you have already installed jdk on your system then run it
ruclips.net/video/uadGsNA6h5Q/видео.html
you will get how to download jdk and run it
it works only on windows 12 and its version is 12
thanks.

Its called CamelCase
when i write system.out.println ? there is wrong with out .
replace "s" with "S" in system for the first "s".

What is 'args' for?
it's for when you want to pass arguments to the main method, usually when running the program from a terminal, but you don't really have to worry about it too much for now.
Can't I just do public static void main()
{
}
Seems to work for all my programs

Sure thing. Thanks man.
