Computational thinking for a software developer/computer programmer is a critical skill that is consistently applied. This lab requires you to develop a solution using Java object-oriented programming that simulates creating and managing a collection of songs. The system manages information about a collection of songs. The system stores the following information (for each attribute, choose any type that you think is appropriate--you must be able to justify the decisions you make): Collection Name: the name for the collections of songs Collection list of songs: the system allows you to create a collection with unlimited songs. You can add the same song multiple times to any given collection. Hence, the collection allows songs to be duplicated Note: other system functionalities can be inferred from the given JUnit test. o NoSystem.out.printlnstatementsshouldappearinit.o NoScanneroperations(e.g.,input.nextInt())shouldappearinit. Instead, declare the method's input parameters as indicated...

Sequence diagram Create a UML sequence diagram that will show your clients how the system’s classes will interact when customers are buying their flight tickets on the booking website. How to create your assignment Review the code responsible for adding a new item. Make a sequence diagram that captures the interactions of objects in the app when a new item is added. Your sequence diagram should contain the following classes: AddItemActivity ItemList Dimensions Item And contain calls of the following methods: onCreate() loadItems() saveItem() Dimensions constructor Item constructor addItem() saveItems() Lastly, the activation of AddItemActivity should start with the call to "onCreate()"
