Task 1 – Data Import Import the crimedata.sql file into your mysql server database using the PHPMyAdmin application on the LAMP server. Make sure that the import creates a crimedata table and has the following columns: crime_ID, month, reported_by, falls_within, longitude, atitude, location, LSOA_code, LSOA_name, crime_type. The explanation of each column is provided in the appendix A. If imported correctly, your table will have 66,683 records. Task 2– Unit Testing Write Unit Tests for all your classes and methods you implement in tasks 3,5, and 6. Task3 – Database Handling Create a class called DatabaseHandler. This class will have a method called handleDbConnection. It has no input parameters and returns a java.sql.Connection object. You should use your mysql credentials here to make a connection to the database that contains the crimedata table. Other methods and classes implemented as part of tasks below will call the handleDbConnection method to use the connection object a...

Implement In Java the Snapshot pattern depicted In the UML diagram in snapshot.pdf file. Please pay special attention to the access modifiers (+: public, -: private or no sign: package) for each attribute and operation and implement them in Java. The UML diagram follows some of classes defined in the Snapshot pattern in book (page 371) which has more details than in my diagram. Please read the descriptions about them in the book. My MdestonefementolFhas two methods and my private static class Mllestonenemenfo has three attributes. Here are a couple of extra points you need to be aware of: • GameUserInterface class Is the program that user Interacts with. • gets user selected file through JFileChooser  Uses GameSerializer which is the action listener that serializes (saves) GameModel object Into a user-specified file.  Uses GameDeserializer which Is also an action listener that deserializes (read object) from a user specified file.  Gets MilestoneMementoManager fro...

A database is required for the Old Print, a web-site that specialises in books printed before 1950. While the site is open to the public, certain services are only available to members. Each member has a unique membership number (N 8 0) recorded along with their name (C), address (A), email address (S 30) and expiry date (D). A member might also have a phone number recorded (S 14). Any visitor to the site can check for what books there are copies currently on offer. Each book (offered now or in the past) has its unique ISBN (S 12) and title (S 70) recorded along with an assigned category code (S 3). For each possible category code such as 'SFI', a description (S 30) such as 'science fiction' is recorded. The book's one to many authors are identified along with its publisher, edition (N 2) and the publication date (D). Each copy of a book has a unique inventory number (N 8 0) recorded along with a price ($ 4) and the date (D) when it became available. There may be ...

The Race A number of racers will compete in a race with three obstacles: The Forest, The Mountain and The River. Before the first obstacle and between any two obstacles, the racers will stop for rest and food (by sleeping for a random time). The sequence of events will be something similar to: Rest Forest Rest Mountain Rest River Get Home Note: you will need to keep track of the time when a racer started a specific obstacle and when it ended that obstacle, together with the time when the racer started the race until he finished the race. The obstacles are described below: The Forest: You will have to use the setPriority( ), getPriority( ) and yield( ) methods. At the entry to the forest, the racer will try to rush as much as possible (simulated by increasing its current priority by a randomly generated number between 0-4). The racer using a compass will have to find in the forest a map that contains a magic word. The forest will be a file of more than 300 but les...

Monash Library Services (MonLib) The local Monash Municipality maintains several libraries for its residents across the municipality. For each branch Monash Library Services assigns a branch code (an incremental number for each branch with the first branch using a code of 100). The branch name, address and contact phone number are also recorded. Each branch is assigned a manager. Due to the small size of some of the branches a particular manager may manage several branches. Each manager is assigned a manger id. Monash Library Services record a managers name and contact phone number. All managers are assigned one particular branch as their home branch. Monash Library Services maintain records of current loans of books to borrowers. Each borrower is identified by a borrower number and each copy of a title by a barcode number (the library may have more than one copy of any given title). When a borrower first registers to borrow books the branch where they register is recorded as their...
