This code is meant to be a simple quiz, but I am getting 4 errors that I cannot figure out. Thanks in advance.




import java.io.*;
public class Quiz
{
public static void main(String args[])
{
int correctCounter;
InputStreamReader reader;
BufferedReader buffer;
keyboard = new BufferedReader (new InputStreamReader (System.in));
}

String seekResponse;
{ System.out.println("Welcome to Dan's Quiz .. ");
{
// choose the subject
System.out.println("enter M for Math, S for Science or x for exit");
seekResponse = keyboard.readline();
if (seekResponse.equals ("M")) //Select the Math quiz
{
System.out.println("What is the sum of 120 & 120?"); //Math Question1
System.out.printIn("a. 0");
System.out.printIn("b. 240");
System.out.printIn("c. 220");
System.out.printIn("Press X to exit");
seekResponse = keyboard.readline();
if (seekResponse=("a"))
System.out.println("incorrect answer");
if (seekResponse.equals ("b"))
System.out.println("correct");
if (seekResponse.equals ("c"))
System.out.println("incorrect answer");
else if (seekResponse.equals ("x"))
exit; // do exit logic
System.out.println("What is the product of 12 & 12?"); //Math Question2 Line34
System.out.printIn("a. 144");
System.out.printIn("b. 24");
System.out.printIn("c. 1");
System.out.printIn("Press X to exit");
if (seekResponse.equals ("a"))
System.out.println("correct answer");
if (seekResponse.equals ("b"))
System.out.println("incorrect answer");
if (seekResponse.equals ("c"))
System.out.println("incorrect answer");
else if (seekResponse.equals ("x"))
exit;// do exit logic
}
else if (seekResponse.equals ("S")); //Select the Science quiz
{
System.out.println("A snake is a member of which animal group?"); //Science Question1
seekResponse = keyboard.readline();
System.out.printIn("a. Mammal");
System.out.printIn("b. Amphibian");
System.out.printIn("c. Reptile");
