Consider the following declarations in Java:

public class XClass

{

private int u;

private double w;

public XClass ()

{

}

public XClass ( int a , double b)

{

}

public void func ()

{

}

public void print ()

{

}

}

XClass x = new XClass (10 , 20.75);

a. Write the definition of the constructor with parameters of the class XClass so that the instance variable u is initialized to the value of a and the instance variable w is initialized to the value of b.

b. Write a Java statement that prints the values of the instance variables of x.

c. Write a Java statement that creates the XClass object t and initializes the instance variables of t to 20 and 35.0, respectively.
