Given the following UML diagram: Part 1: Implement the following classes: Note that some files can be encrypted. (65 pts) Folder (30 pts) -name: String - File: ArrayList + Folder(name: String) + getName(): String + addJava(j: Java): vold + addDatabaseld: Database): vold + getFile(): ArrayList + countJaval): int + countEncryptedjaval): int + searchForDb((name: String): Database + toString(): String File (15 pts) -name: String - size: int - encrypted: boolean + File ---All Parameters) + setters/getters +toString(): String Database (10 pts) - tables: int + Street ----All Parameters----) + setter/getter + toString(): String Java (10 pts) - Classes: int + Java-All Parameters) + setter/getter + toString(): String For each class you should write a toString method that returns (string) the characteristics of class. 1. Create File Class (superclass) of all files (Java, Database). a) Declare three attributes as follow string name, integer size, and Boolean encrypted. b) Define a constructor with all parameters c) Implement the setters and getters 2. Create the Java class which extends File class a. Declare integer attribute called classes which hold the number of classes in a java file b. Define a constructor will all parameters an inherit the attributes from the super class c. Implement the setters and getters 3. Create the Database class that extends File Class a. Declare integer attribute called tables that holds the number of tables in Database file b. Define a constructor will all parameters an inherit the attributes from the super class c. Implement the setters and getters 4. Implement a Class called Folder that includes un ArrayList containing files a. addJava() add a file of type java to the folder (the ArrayList) b. addDatabase() add a database file to the folder (the ArrayLits) c. getFile() return a string showing the information about all files in the ArrayList. d. countJava return the number of java files in a Folder e, countEncryptedJavu() return the number of encrypted java files in a Folder f. searchForDBO) display the name of given file name in a folder if found or display "not found" if it's not in the folder
