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…
