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.
Explanation / Answer
a) public XClass ( int a , double b) { u = a; w = b; } b) x.print(); c) XClass t = new XClass (20, 35.0);
