3. Consider the following schedule: S': R1(X), R2(x), W1(Y), R3(Y), R2(Y), W2(x), R3(W), W3(y), R4(w), R4(2),
I
W4(W), R1(Z), WI(Z)
Is this given schedule conflict serializable? If yes, prepare a precedence graph and
write the order of execution for transactions.

[a] create a class called “cycle” which has two instance integer variables as properties, “numberofwheels” and “weight.” create a constructor with two parameters, using the same variable names in the parameter list. assign each variable to numberofwheels” and “weight” respectively. write a separate application to test the class and display its properties. note: do not change the names of the instance variables or the variables listed in the constructor’s parameter list. [b] edit your class cycle by adding a default constructor which will assign the default values of 100 to represent the numberofwheels, and 1000 to represent the weight, by invoking a call to the other constructor. modify your application created in [a] to test the class.
