Design a ListBox component that allows selecting multiple items and implement methods to add items, remove items, and get the selected item

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…

Computer Science Part C: Interactive Driver Program Write an interactive driver program that creates a Course object (you can decide the name and roster/waitlist sizes). Then, use a loop to interactively allow the user to add students, drop students, or view the course. Display the result (success/failure) of each add/drop.

Lab Goal : This lab was designed to teach you how to use a while loop.   Lab Description (JAVA PROGRAMMING): Remove all occurrences of the removal string from the original string. Each time you take out the removal string you must also remove the letter that preceded the removal string. After you remove a string and its leading character, you must check to see if any more occurrences of the removal string exist. Sample Data : xR-MxR-MHelloxR-M R-M sxsssxssxsxssexssxsesss xs fuxqwexqwertyxqwexqwe     Sample Output : xR-MxR-MHelloxR-M - String to remove R-M Hello sxsssxssxsxssexssxsesss - String to remove xs sesss fuxqwexqwertyxqwexqwertyrtyxqwertyrtyn - String to remove qwerty fun dogdogcatddodogdogdoggog - String to remove dog catgog   algorithm help use indexOf to look for more removals while you have more removals { take out the current removal using substring use indexOf to look for more removals }           I need help with assignment: "String Cleaner"   StringRemover.js: //(c) A+…
