}

You can practice your codes in
@codeCompiler_bot

It supports short coding 👇

For upper part of java you can simply write

"Start"

And for lower part

"End"

Then in middle you can write java code

But one thing more
You don't need to write big print statement like

System.out.println();

Just write

pt

And then your code without parenthesis

Full example

"Start"
Pt "hi this is mine short java"
"End"

You can run this code on @codeCompiler_bot using
/jv command

You can convert this code in real java code by using
/rjv command

Here is more short code example

import java.util.Scanner;

"Start"
        Scanner scanner = new Scanner(System.in);

        Pt"Enter an integer: "
        int number = scanner.nextInt();

        Pt"You entered: " + number

        scanner.close();

  "End"
