Expert Solution & Answer
Chapter 11, Problem 7SA
Explanation of Solution
The inheritance is a public one - the public members of the base class remain public in the derived and the private members of the base class remain private unless re-declared otherwise in the derived class. Hence, the private members of the object newCylinder are the following:
height – as it is the ...

#3Run the code
class Param3 {
public int x;
private void increase(int p)
{
x = x*p; }
public void calculateX(int y) {
increase(y);
}
public int getX() { return x; }
}
// in another class
Param3 q3 = new Param3();
q3.x = 5; q3.calculateX(7);
System.out.println(q3.getX());
what would be the answer for the last two lines ? also above were x = x*p do both x in here are the fields? wouldn't that be cnofusing?
