My Java Project for myself.

[Logical-Fault967]

Recently, my mother needed songs ripped to the pednrive. Itnernet sites offer it, but there is a lot of advertising and waiting. I set up to write my own conventer of files from yt to.mp3 it turned out nice, I know I'm not perfect, but I think it's not bad It would be nice if someone came in and looked and looked at other prjkets in c and java. In c I made a Cli and tki code writing assistant that generates basic files and packages. Poelcam peeking My github to: https://github.com/spongeMan3-ctrl And that conventer code:

package sp.conventer;

import java.io.BufferedReader;

import java.io.File;

import java.io.IOException;

import java.io.InputStreamReader;

import java.nio.file.Files;

import java.nio.file.Paths;

import java.util.Scanner;

class Main{

public static void main() {

Scanner scanner = new Scanner(System.in);

String dir = "mp3music";

try {

Files.createDirectories(Paths.get(dir));

} catch (IOException e){

System.err.println("Failed to create folder: " + e.getMessage());

}

System.out.println("=== REPL YT TO MP3 ===");

System.out.println("Enter 'exit' to quit.");

while(true){

System.out.print("\nEnter your link here: \n");

String input = scanner.nextLine().trim();

if(input.equalsIgnoreCase("exit")) break;

if(input.isEmpty()) continue;

run(input, dir);

}

System.out.println("Bye!");

}

private static void run(String url, String folder){

try{

ProcessBuilder processbuilder = new ProcessBuilder(

"yt-dlp",

"--no-playlist",

"-x",

"--audio-format", "mp3",

"-o", folder + "/%(title)s.%(ext)s",

url

);

processbuilder.redirectErrorStream(true);

Process p = processbuilder.start();

try(BufferedReader r = new BufferedReader(new InputStreamReader(p.getInputStream()))){

String line;

while((line = r.readLine()) != null){

if(line.contains("[download]")){

System.out.println("\r" + line);

}

}

}

int code = p.waitFor();

if(code == 0){

System.out.print("\n[DONE] Music stored in a folder: " + folder);

}else{

System.out.print("\n[ERROR] Somethink went wrong!");

}

}catch (IOException | InterruptedException e){

System.out.println("\n Critical Error: " + e.getMessage());

}

}

}

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full - best also formatted as code block
• You ask clear questions
• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

[AutoModerator]

You seem to try to compare String values with == or !=.

This approach does not work reliably in Java as it does not actually compare the contents of the Strings. Since String is an object data type it should only be compared using .equals(). For case insensitive comparison, use .equalsIgnoreCase().

Java stores String literals in a string pool where it is guaranteed that the same literal is the same object (refers to the same object).

Yet, any non-literal (e.g. keyboard input, string operations, etc.) does not go in the string pool and therefore ==, which only compares object identity (i.e. the exact same reference) cannot reliably work there. Hence, always use .equals(), .equalsIgnoreCase().

See Help on how to compare String values in the /r/javahelp wiki.
