Create an application that: 1. Is implemented in a single Java (.java) file named “MatchMaker.java” 2. Successfully compiles with “javac *.java" and successfully executes with “java MatchMaker” 3.

Question

Object-Oriented Programming ❤❤❤ Matchmaker with Java ❤❤❤ Summary: Create a Java application that will determine your true love. Prerequisites: Java, VS Code, and Terminal In this assignment you will develop and test a command-line application written in the Java language that asks questions to determine if a person is your true love. More specifically your application should ask five questions in the form of statements and allow the user to respond to each statement with the numbers 1 through 5 with 1 indicating strongly disagree and 5 indicating strongly agree. You will then compare the person’s answers with your desired “true love” answers. The closer the answers are to your desired “true love” answers the better match the two of you are for each other. For example, suppose you choose the statement “Broccoli is delicious.” and your desired answer was 1 (strongly disagree) because you really don’t like broccoli. If the application user entered 4 (agree), then the two of you would not be a very good match based on that question. In the broccoli example above you would want to calculate your question compatibility score for this question by taking the absolute value of the difference between their answer and your desired answer. In addition, each question should have a weighting of 1 to 3 based on how important that question is to you. For example, the “Broccoli is delicious.” statement may only have a weighting of 1 where a “I could play Fortnight for hours.” question may be more important to you and deserve a weighting of 3. After all five questions are answered, you will need to add up the weighted question compatibility scores for each of the five questions and subtract the value from 100 to calculate a final compatibility score that has a maximum value of 100. You will also need to set three threshold scores. One for true love, one for possible friends, and one for run away. You utilize your programming knowledge, creativity, and good taste to set and adjust the thresholds, phase the results, and share the results to the user. Be sure to review and test your ideas for the application with a friend or classmate to get some usability feedback. If you are looking for some examples of what this application might look like if it was a command line application and Dr. Klump was creating it, you can see it here [link]. I’m sure you can improve on his design. Requirement 1 Create an application that: 1. Is implemented in a single Java (.java) file named “MatchMaker.java” 2.
