Newbie, having a problem with Input in Java

Question

Hello, Thank you for reading this!
I am having a hard time understanding this.
I am having an awful time with Input into variables. The following code I have got where what I type in anything from the keyboard it stores it in the variable String "name", but when I do an If statement with the variable it does not equal when I want it too.
Example,
If I type in "yes" and it should display in the output
You said yes
science
It will do the first part, what I typed in but when I say
if answer == "yes" then display science
it always goes with the else statement.
It is little things like this that blows my mind. How am I going to tell it with an conditional operator if it does not look at them the same?
It says I typed in yes I know this by thr System.outprintln("You typed, answer);
but when I do an if answer == "yes" and inside the variable "answer" is "yes"
it will not match.
Why????????
Is it because I am also pressing the enter key and it see's this?
I have read the book over and over, I don't know what I am missing.
When you look at an Input example in the book they are almost always numbers like:
If (temp <40)
System.out.println("Not freezing");
Please help me with the input and conditions.
Below is just simple code, look at the If area?
import java.io.*;
public class test
public static void main(String args[])
String name;
BufferedReader reader;
reader= new BufferedReader(new InputStreamReader(System.in)); System.out.println("Do you want to take the test? answer yes or no");
try {
answer =reader.readLine();
System.out.println("You said " + answer);
if (answer == "yes")
System.out.println("Science");
else
System.out.println("Arts");
catch (IOException ioe) {
System.out.println("I/O Exception Occurred");

You could tidy it up a bit on other ways too;-import java.io.*;
public class test{
   public static void main(String args[]){
      String answer = "";
      BufferedReader reader= new BufferedReader(new InputStreamReader(System.in));
      System.out.print("Do you want to take the test? Please answer \"yes\" or \"no\": ");
         try {
            answer =reader.readLine();
            System.out.println("You said " + answer);
            answer = answer.toUpperCase().trim();
            if (answer.equals("YES") ) System.out.println("Science");
            else System.out.println("Arts");
         catch (IOException ioe) { System.out.println("Exception "+ioe);
