Answer 1

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner mo = new Scanner(System.in);
int y = mo.nextInt();
for (; y<30; y++)
{ System.out.println(y); }

}
}

// nextInt shouldn't be used inside for loop initialization because input has been acquired prior to the loop structure.

Answer 2

you are initializing the same variable(y) twice...
