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 member func so that u is set to 10 and w is set to 15.3.

b. Write the definition of the member print that prints the contents of u and w.

c. Write the definition of the default constructor of the class XClass so that the instance variables are initialized to 0.
