editIn JAVA, is it possible to write all types of codes in main method?
editI want to write all types of codes in main method, so that no need to instantiate the class or without having to instantiate an object.
public class Main {
public static void main(String[] args) {
int x = 5;
System.out.println(x);
}
}
I don't want to use below code to show same output:
public class Main {
int x = 5;
public static void main(String[] args) {
Main myObj = new Main();
System.out.println(myObj.x);
}
}

- Yes, this is entirely possible.
main()
can have local variables just like any other method. JIP | Talk 09:48, 7 February 2022 (UTC)
I understand very well. Rizosome (talk) 07:35, 8 February 2022 (UTC)

Unzipping files
editHow do I unzip a file without the use of 3rd party websites? I've heard it's really easy but I'm just missing a key point. Hpnzii (talk) 16:04, 7 February 2022 (UTC)
- @Hpnzii: Depends on what OS you're using. If you're on Windows you can do it through the file explorer (Can't provide the exact steps to do so right now as I don't have access to my Windows PC) as long as it's a file in the .zip format. I can't say the same for other OSes though since I've only ever used Windows and Chrome OS (never really encountered .zip files on Chrome OS so I don't know how it works there). ― Blaze WolfTalkBlaze Wolf#6545 16:09, 7 February 2022 (UTC)
- On Windows 10, in file explorer, right-click on the file. One of the menu options is "Extract all...", which then asks you where to put the files — GhostInTheMachine talk to me 16:16, 7 February 2022 (UTC)
- You download and install one of the many file archivers. (By the way, thank you for letting me know that online decompression is a thing, as you may coincidentally just have solved my problem.) Card Zero (talk) 14:00, 9 February 2022 (UTC)
