Transcribed Image Text:a. Write the definition of the default constructor of YClass so that the instance variables of
YClass are initialized to 0.
b. Write the definition of the default constructor of XClass so that the instance variables of
XClass are initialized to 0.
c. Write the definition of the method two of YClass so that the instance variable a is initialized to
the value of the first parameter of two, and the instance variable b is initialized to the value of the
second parameter of two.
Expert Solution
Step 1
Describe Constructors and techniques
A) The default constructor of YClass is defined as follow:
Public YClass()
{
a=0;
b=0;
}
The instance variables are initialized to 0 in mentioned above. As a result, a and b will be zeros. The variables a and b are assigned to 0 as soon as the object is formed.
