import java .io.*;
public class Test{
    public static void main(String[] args) throws IOException{ 
        BufferedReader steffi=new BufferedReader(new InputStreamReader(System.in));
        String name; 
        String answer1=""; 
        int ctr1=0;

       System.out.println("Enter your name:");
       name=steffi.readLine();


       System.out.println("1.What is the name of the developer of java?");
       System.out.println("\tA. Steve Jobs");
       System.out.println("\tB. James Gosling");
       System.out.println("\tC. Bill Gates");
       System.out.println("\tD. None of these");
       System.out.print("Enter your answer:");
       answer1=steffi.readLine();
       if(answer1.equalsIgnoreCase("B"))
       {
        ctr1++;
       }
