Answer 1

$\texttt{\textsf{\large{\underline{The C{o}de!}}}}$

public class Pattern{

   public static void main(String args[]){

       for(int i=1,a=1;i<=4;i++){

           for(int j=1;j<=i;j++)

               System.out.print(a++ +" ");

           System.out.println();

       }

   }

}

$\texttt{\textsf{\large{\underline{O{u}tput!}}}}$
