String a = "Nice vid Alex"; sysout(a);

[@og_gaming2323]

:1: error: class, interface, or enum expected string a = " Nice vid Alex"; ^ :2: error: class, interface, or enum expected sysout(a); ^ 2 errors

[@sowjanyasharma6481]

Great work Alex

[@HussamAdil]

public static void main(String[] args) { //thanks Alex and this another solution using stringbuilder // happy coding StringBuilder name = new StringBuilder( "hussam"); String firstLetter = name.substring(0,1).toUpperCase(); System.out.println(firstLetter); name.deleteCharAt(0); name.insert(0,firstLetter); System.out.println(name); }

[@anuragpanda4216]

What does StringBuilder do?

[@v1araujor1]

Alex, I am looking forward to seeing videos of yours explaining more intermediate stuff in Java. Things like... layout managers? Maybe a series of videos on that matter. Stuff like modelling a project, with MVC, maybe? Hope you read this comment. Love your work!

[@techamatuer8115]

your explanation is much better

[@daives01]

Thank you so much for your videos! They are awesome and I would be really struggling without them

[@sowjanyasharma6481]

Yeaa

[@alexlorenlee]

You're welcome!

[@joethompson8147]

Great job here Alex! I have a gut feeling that String methods will be on the 2020 AP CS"A" somewhere so I looked for good videos and found this!

[@lumdermaku]

☕☕☕☕ Please start using intelliJ with dark mode instead of the ancient eclipse

[@baohoangle3901]

I think eclipse is beter.

[@duckking7642]

Eclipse looks good on mac, and it fits well for his tutorials in my opinion, but if you want to do java then yes I suggest IntellIJ IDEA but other than that, eclipse is good for other programming languages

[@dhananjayand3057]

this is great- however now wondering how we could do this with user input- that would be an un-pre-defined string length- so I wonder if we could get the length and use that to run this string method? yikes my head hurts- help? ;)
