Answer:

//question1

import java.util.*;

class Main {

 public static void main(String[] args) {

   Scanner s=new Scanner(System.in);

   String name=s.next();

   for(int i=0;i<4;i++)

   System.out.print(name+" ");

 }

}

//Question2

import java.util.*;

class Main

{

 public static void main(String args[]){

   String name;

   int rollno;

   String Class;

   Scanner s=new Scanner(System.in);

   rollno=s.nextInt();

   name=s.next();

   Class=s.next();

   System.out.println("The student name is "+name);

   System.out.println("The Student rollno is "+rollno);

   System.out.println("The student studying in "+Class);

 }

}

//question3

import java.util.*;

class Main

{

 public static void main(String args[]){

  int principle;

  double interest;

  int time;

   Scanner s=new Scanner(System.in);

   principle=s.nextInt();

   interest=s.nextDouble();

   time=s.nextInt();

   double SI=(principle*interest*time)/100;

   System.out.println("The simple interest is "+SI);

 }

}

//question4

import java.util.*;

class Main

{

 public static void main(String args[]){

  double bill;

   Scanner s=new Scanner(System.in);

   bill=s.nextDouble();

   double tax=bill*5/100;

   double total=bill+tax;

   System.out.println(total);

   }

}

//question5

import java.util.*;

class Main

{

 public static void main(String args[]){

  int length;

  int breadth;

   Scanner s=new Scanner(System.in);

   length=s.nextInt();

   breadth=s.nextInt();

   double area=length*breadth;

   double perimeter=2*(length+breadth);

   System.out.println("Area is "+area);

   System.out.println("Perimeter is "+perimeter);

   

 }

}
