Print 1 in every position except position number 1 (where it supposed to print 1)

You can give it an input as a command line argumet, this will be the number of ones printed.

Download from the terminal:

$ wget https://raw.githubusercontent.com/donno2048/Confusing/main/Main.java

Try looking in the terminal to see what is going on:

$ cat Main.java
import java.lang.reflect.Field;
import java.util.Random;
public class Main {


        public static int j = 100;
        public static void main(String[] args) {


                if (args.length > 0 && args[0].length() > 0)
                        j = Math.min(Integer.parseInt(args[0]) + 1, j);
                for(int i = 1; i < j; i ++)
                        System.out.printf("%d", i);


       }


}



$ javac Main.java
$ java Main;echo
211111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111
$ java Main 10;echo
2111111111

There's a "Demo"

There is another similar code in HelloWorld.java get it with wget

$ wget https://raw.githubusercontent.com/donno2048/Confusing/main/HelloWorld.java

Then run it:

$ cat HelloWorld.java
import java.util.Random;

public class HelloWorld

{

        public static void main(String[] args)

{

}

}

$ javac HelloWorld.java
$ java HelloWorld
hello world
