import java.util.Scanner;

public class PrintEx {

   Scanner sc = new Scanner(System.in);
   int i;
   double d;
   String s;
   System.out.println("Enter String : ");
   s=sc.next();
   System.out.println("Enter integer : ");
   i=sc.nextInt();
   System.out.println("Enter double: ");
   d=sc.nextDouble();
   //printing the 4 spaces before int
   System.out.printf("%4d\n",i);
   //printing only 2 fraction values
   System.out.printf("%.2f\n",d);
   System.out.printf("%s",s);
