What are different states of an java applet? Explain applet life cycle with suitable state diagram.

-

 There are five primary methods in the Applet class which provide the framework for just about every applet. An applet can be in any one of the following states during its lifecycle.



Newborn State: Applet enters into this state when init() method is invoked. This method is used to initialize any components of your applet before the program begins to run. The init method is called after the param tags have been processed by the JVM. Overriding init() method is optional while creating an applet. Like the main method of standalone java programs, in case of applets init method is always executed first. 

Syntax of init method

public void init()

 Running State: Applet enters into running state when start() method is invoked. The start method is automatically called once the browser calls the init method. This method is also called automatically whenever a user returns to the page containing the applet Paint method is called immediately after start, the paint method is what displays your applet on a webpage. Paint is also called any time the applet needs to repaint itself Overriding start() method is also optional while creating the applet. But, the overriding paint() method is mandatory while creating applets.

Syntax of start method

public void start()

Syntax of paint method

public void paint(Graphics)

Idle State: Applet enters into an idle state when stop() method is invoked. The stop is automatically called by the browser when the user moves off the page where the applet is embedded. It can be called multiple times within the same applet. Overriding the stop() method is again optional while creating an applet.

Syntax of stop method

public void stop()

End State: Applet enters into end state when destroy() method is called. Once the browser shuts down, the destroy method is called automatically and removes any resources that would otherwise be left behind by the applet. The overriding destroy() method is also optional while creating an applet.

Syntax of destroy method

Public void destroy()

Suppose that a data warehouse for Big-University consists of the following four dimensions: student, course, semester, and instructor, and two measures count and avg_grade. When at the lowest conceptual level (e.g., for a given student, course, semester, and instructor combination), the avg_grade measure stores the actual course grade of the student. At higher conceptual levels, avg_grade stores the average grade for the given combination. a) Draw a snowflake schema diagram for the data warehouse. b) Starting with the base cuboid [student, course, semester, instructor], what specific OLAP operations (e.g., roll-up from semester to year) should one perform in order to list the average grade of CS courses for each BigUniversity student. c) If each dimension has five levels (including all), such as “student < major < status < university < all”, how many cuboids will this cube contain (including the base and apex cuboids)?

a) A Snowflake Shema is shown in figure below: b) The specific OLAP operations to be performed: 1. Roll-up on course from course_id to department. 2. Roll-up on a student from student_id to university. 3. Dice on course, student with department ="CS" and university = "biguniversity" 4. Drill-down on a student from the university to student_name. c) N = 4 dimensions The cube will contain 54 = 625 cuboids.

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?

  b) The specific OLAP operations to be performed are: 1. Roll-up on date from date id to year. 2. Roll-up on spectator from spectator id to status. 3. Roll-up on location from location id to location name. 4. Roll-up on the game from game id to all. 5. Dice with status= “students”, location name= “GM Place”, and year=2004

Suppose that a data warehouse consists of the three dimensions time, doctor, and patient, and the two measures count and charge, where a charge is the fee that a doctor charges a patient for a visit. a) Draw a schema diagram for the above data warehouse using one of the schemas. [star, snowflake, fact constellation] b) Starting with the base cuboid [day, doctor, patient], what specific OLAP operations should be performed in order to list the total fee collected by each doctor in 2004? c) To obtain the same list, write an SQL query assuming the data are stored in a relational database with the schema fee (day, month, year, doctor, hospital, patient, count, charge)

Solution: a) Star Schema is shown in the figure below: b) First, we should use the roll-up operation to get the year 2004(rolling-up from the day then month to a year). After getting that, we need to use the slice operation to select (2004). Second, we should use roll-up operation again to get all patients. Then, we need to use the slice operation to select (all). Finally, we get a list of the total fee collected by each doctor in 2004. So, 1. roll up from day to month to year 2. slice for year = “2004” 3. roll up on patient from the individual patient to all 4. slice for patient = “all” 5. get the list of the total fees collected by each doctor in 2004 c) Select doctor, Sum(charge) From fee Where year = 2004 Group by doctor
