Thank you! With every video I feel like you are good in finding sweet spot between teaching a lot but not too much at one time :)

[@SolidSnake4705]

The nuclear launch codes folder never gets old, I wonder whats in there :D

[@isaie9057]

hello again my friend thank you for the Tutorial

[@BroCodez]

thank you for watching

[@greekrapindustry]

38:58 the reason this guy is the best, out of 10 different playlists, with 100 or more videos in each with every each one having a duration of 10 min or more, he isnt bored and he still leaving amazing tuturial details like this one, its like even if u wanted to find this clip of him messing around with the fontSizeSpinner that he created, u couldnt, its so deep hidden but yet ultra entertaining

[@trailblazer4227]

What you do is pure art!

[@marcusaureliusregulus2833]

Wow. Now I see why people say it takes a lot more lines of code to do the same in java

[@prizepig]

This great for tying all the previous lessons together. Thanks for making these!

@Bro Code i really like this tutorial u made :)
but i think u should make a "find" function,im also making a option that makes the framecolor yellow,black,or white (includes textarea)

There is another way to read the text in a file , which you have mentioned before in file reader .
/*
// another style
public void open() {

fileChooser = new JFileChooser() ;
fileChooser.setDialogTitle("Open file") ;
fileChooser.setCurrentDirectory(new File("./src")) ;
// filter out the files that don't have specific extension name (.txt) .
FileNameExtensionFilter filter = new FileNameExtensionFilter("Text files" , "txt") ; // (title , file extension name)
fileChooser.setFileFilter(filter) ;

// show the window for opening file .
int response = fileChooser.showSaveDialog(null) ;
// if [Open] is pressed or [file] is double clicked .
if (response == JFileChooser.APPROVE_OPTION) {

// get the absolute pathname of opened file .
File file = new File(fileChooser.getSelectedFile().getAbsolutePath()) ;;

FileReader reader ;

// if opened file is file , not folder .
if (file.isFile()) {
try {
reader = new FileReader(file) ;
// clean the textArea before you add file text on it .
textArea.setText("") ;
int data = reader.read() ;

while (data != -1) {
textArea.append(String.valueOf((char)data)) ;
data = reader.read() ;
}

// it's a good behavior to close I/O stream when not in use .
reader.close() ;

openedfileText = textArea.getText() ;
// remind user the open process has finished .
JOptionPane.showMessageDialog(null , "You have opened successfully .") ;
}
catch (IOException e1) {
e1.printStackTrace();
}
}
}
}

how to make the selected text become bigger font size not all text?

wow thx

[@nawfalnjm5699]

thanks man , great video !

[@hempathak7001]

your code is correct but in full mode menubar not display correctly can you please do this in netbeans ide where we can design the layout first then code it for logic. rest things is good.

[@tasneemayham974]

Hey!!
I was wondering how to make a button that bolds and un-bolds the textArea. I made it so that it will bolden it, but I don't know how to make it un-bold using the same button. Do you think you could help me, please? Thank you!!

Hey Bro, how to create editor without TextArea element, only need drawString() from paintComponent() in JFrame?

[@sayuri-san8807]

Does the code work on netbeans?

[@socaljusticewarrior558]

I came across a weird problem the second time I did this. My scroll bar doesn't readjust when I add more text. I was wondering if there was some method by which I could change this. I tried looking myself, but alas it is impossible to know what the heck Oracle ever means by anything.

[@socaljusticewarrior558]

Update. It's because I gave both the label and the scroll panel dimensions. 😅

[@arkamukhopadhyay2177]

textArea.setText("Your videos are the best");

I used textArea.setText(""); to clear the text but there might be a better way.

[@eddiegutierrezz]

@@jett8692 Me too, but with the font chooser, size and color. Need to restart each one to youre default one.
