[Solved]Create New Project Bluej Name Lastname Lab2 App Eg Smith Lab2 App Create New Class Using N Q37196460
- Create a new project in BlueJ and name it LastName-lab2-app,e.g., Smith-lab2-app.
- Create a new class using the “New Class…” button and name itApp (be sure the A is capitalized and the other letters are not;Java is case-sensitive and the class must be named exactly asgiven).
- Open the App class to edit the source code.
- Select and delete all the source code so that the fileis empty.
- Copy in the starting source code found here: Lab 2: AppStarting Source Code
- Update the header comment block and document your changes asyou work.
- Adjust the header comment block at the top of the file:
*
* Modifications:
* …
* CT: Added method to print app basic info
* YN: … ← List changes you make prefaced by yourinitials
*
* @author Cara Tang, Your Name ← Add your name
* @version 2017.12.30 ← Update the version to the currentdate
*/ - Whenever you add a new method, include a documentation blockthat describes what the method does. For example:
/**
* Return the app rating
*/
- Adjust the header comment block at the top of the file:
- Complete the TODOs in the code, modifying and implementingmethods as described. Be sure to follow the specifications as givenin the TODO comments, for example the methods must be named asgiven (with correct spelling and capitalization).
- Before submitting your project, delete the TODO comments. TODOsrepresent a task that still needs to be done, and when you completea TODO it should be removed. There should not be anyTODOs in your submitted project(unless you didn’tcomplete the project).
- Adhere to Java style guidelines as described in AppendixJ.
