Simple Java Script "Quiz Script"

Just learning a little bit of JavaScript today. Here is a simple little quiz script i wrote for anyone who wants to have a little fun. Enjoy.

<script>
var num_correct = 0; // correct answers
var good = 'Awesome! Thats correct!';
var bad = 'Sorry, that is incorrect! :( ';

// question 1 answer prompt
var user_ans = prompt('Question 1: How many States are in the US? ');

if(user_ans = 52){
  num_correct += 1;
  alert(good);
}else{
  alert(bad);
}

// question 2 answer prompt
user_ans = prompt('Question 2: What color is healty grass? ');

if(user_ans.toLowerCase() === 'green'){
  num_correct += 1;
  alert(good);
}else{
  alert(bad);
}

// question 3 answer prompt
user_ans = prompt('Question 3: What country is the Brand "Sony" from? ');

if(user_ans.toLowerCase() === 'japan'){
  num_correct += 1;
  alert(good);
}else{
  alert(bad);
}

// question 4 answer prompt
user_ans = prompt('Question 4: Question What color is rgb(255,000,000)? ');

if(user_ans.toLowerCase() === 'red'){
  num_correct += 1;
  alert(good);
}else{
  alert(bad);
}

// question 5 answer prompt
user_ans = prompt('Final Question: Name a famous/popular programming code that is 4 letters long and starts with a J : ');

if(user_ans.toLowerCase() === 'java'){
  num_correct += 1;
  alert(good);
}else{
  alert(bad);
}

// Issue prizes below

if(num_correct == 5) { // Gold 5 correct
  alert('Congrats!! You answered 5 questions correctly! YOU GET THE GOLD CROWN!' );
}
  else if(num_correct >= 3){ // silver 3-4 correct
  alert('Hey! Not to bad! Because of your valiant efforts answering '+ num_correct + ' questions correctly, you have won a silver crown. Good job! ');
 
}
  else if(num_correct >= 1){ // bonze 1-2 correct
  alert('I must say....not your best. You only answered ' + num_correct + ' question correctly. What the heck,  here is a BRONZE crown. Better luck next time.');
 
}
  else{ // no crown..sorry 0 correct
  alert('Hmmm....how did you even get your computer to work? You did not answer 1 question correctly. Next time, study up, and try a little bit harder. Best of luck! ');

Software Engineering: Image Analysis with Java/JavaFx

Its been a little while since my last post, but I have been busy.
It is weird to travel through school and be tested. At every turn we feel like the work we are tasked with is nuisance. As we continue to push to meet our deadlines and develop projects to meet the expectations we learn why we love what we do. This is why computer science is so great. Every challenge instills a love and drive for something we never thought we would enjoy. All that being said, I have been working on a project for software engineering that I never thought I would enjoy. Image analysis. It has been roughly 3 weeks or so into my project development and it is almost like an addiction. blah blah blah, right. anyway, I'm here to show what has been made so far.

I have been working with javafx, fxml, jdbc, and eclipse. This hasn't been a picnic but has yielded a pretty nice project so far. The idea of this project is to take an image, and some data from that image, and use it to compare the likeliness of that image to another. My code, and project so far, is really rough and "dirty" as they say for a quick solutions, but I'm open to suggestions and help. Here are screen-shots of what I have so far.

The code is overloaded, dirty, and probably not very efficient but this is my learning curve as of late. I don't have much time to fix much before it is due. The database adapter is still in works but all the code can be found here:
 https://github.com/GettinDatFoShow/ImageAnalysis.git

For anyone who is interested in doing image comparison for their own projects.
Please don't shower me with comments of how ugly or incorrect the code is. I put it together in short time. My goal is to continue to improve it over time and to work with others who have questions about how they would like to do image comparison.

The percentages in the program have been decided in this way:
I decided to first separate the rgb vales and count up a total for each, then divide them by the total that they could be per the pixel count. ie. add up all red values then divide by 255*how many pixels there were.
for colorfulness, I defined it as: the total unique values of each three valued pixel, ie. 255-255-255 then divided the total by the amount of pixels in the image as a total prospect for different values that could occur.  I realized that the colorfulness of a photo is purely defined by the person designing the program and after tough consideration, this is where I arrived. I WOULD LOVE someone else's opinion on how to present this detail. Anyway, this is here because I love to code and I love creativity. So, I would love to hear your
opinions. Thanks, and code on.

Here is the absolutely awful and badly mad image compare image class otherwise known as ICImage.java


remember, this does not include the javaFX controller, or fxml or main class which can all be found in the git hub link. enjoy. (ps, i wish i could have commented more but if you have questions, please ask.)
