Your job is first to debug the ScoreGenerator class and then to finish the Character class.Įach Character has a name and six abilities. Imagine you are working for a game-programming company that is developing an RPG (role-playing game.) When you are finished with the SlotMachine class test it thoroughly and convince yourself that it works properly.ĭungeons and Dragons is a role-playing game where players use dice to generate personae (characters) that they will act the role of in various fantasy settings. Using the scheme shown above, print out the results. It needs to look at the face values of all of the dice and compare them. You may need to change the method calls to reflect the method names you used in the DiceCup class. Replace the text that reads "Put the name of your game here!" with the name of your Slot-machine. The crankArm() method is written for you. The constructor for SlotMachine simply calls the constructor you wrote in the DiceCup class. Notice the only field of the SlotMachine class. Follow the instructions found in the comments. When you are finished with the DiceCup class and you are convinced that it works properly, open the SlotMachine source. Making your additions in the order that you find the comments in is probably the easiest way to go. Each time you add a feature to this class, compile it and test it before moving on. This class should make use of the Die class. You won't have to make any changes to it.
#Statistics bluej program code#
Your lab instructor will explain the code for the Die class. It awards prizes according to the following scheme: When you invoke the crankArm( ) method, it will generate 3 random integers between 1 and 6 and display them.
This program simulates a simple slot-machine. These variables will be initialized first, before the initialization of any instance variables.Open the project with BlueJ. Static variables are initialized only one time, i.e.Static variables can be accessed by calling with the class name.The naming syntax is the same as instance and local variables in case of static variables are not declared public and final. When static or class variables are declared as public static final, then variables names are all in upper case.For numbers the default value is 0, for Boolean the default value is false and for object references the default value is null. Default values of static variables are same as instance variables.When the program starts static variables are created and when the program stops, static variables are destroyed.Static variables are rarely used other than it is declared final and used as either public or private constants. Static variables are stored in static memory.A single copy of each variable per class is to be shared by all instances of the class.Static variables are also known as Class variables which are declared with the “static” keyword in a class.Important Points About Static Variable To Remember:
With the help of static variable we make our program memory efficient. S2.display() // call the display function using the s2 object S1.display() // call the display function using the s1 object (rollno+" "+name+" "+college) // print the value of roll no, name and college *Method For Displaying Student Details*/ Static String college ="GGGI" //Static Variable gets memory once The advantage to make college variable static is that it save memory as it loads once in a class area at class loading time: class Student
The student information will be displayed with different roll no and names but same college. This variable is common to all students so we make it static. The below program has a class Student in which we use static variable college.
So if we make it static, this field will get memory only once in a class area at class loading time. But here, institute refers to the common property of all objects. All students have its unique rollno and name so instance data member is good. When object is created, all instance data members will get memory each time. Problem: Suppose there are 600 students in GGGI institute. Suppose a college name GGGI wants to store students details name and roll number.
