Question

Good afternoon,

I need assistance find the correct answer to the following multiple-choice questions to an entry-level Java assignment as I am confused about how to find it.

Thank you!

Q6 Method squareX is supposed to return the value of class attribute "x" squared, but I messed up :(. What did I overlook? 2 Points class Final private double x; public double squarex() { double x = Math.pow (X, 2); return x; } Variable occlusion O Variable shadowing Method overloading O Block blocking Q7 A class is analogous to 2 Points O A house O A blueprint O An architect O Alecture Q8 In Java an object is 2 Points An inanimate thing A primitive data type An instance of a class O A blueprint Q9 When an object is passed as an argument to a method, what is actually passed is 2 Points O A copy of the object. The name of the object O A reference to the object. None because you cannot pass an object.

Answer 1

Q6)

The concept used in above program is variable shadowing. We use the 2 variables with same name but different scopes. In above program the variable used is x.

So, the correct answer is variable shadowing

-------------

Q7)

A class is analogous to a blueprint. In a class we can define methods and variables, We can use the methods and variables by instantiation of a Class with object.

So the answer is : A blueprint

-------------

Q8)

An object is just creation of an instance of a class. We can create multiple objects for the same class.

So, the answer is : An instance of a class.

--------------------

Q9)

Whenever we want to pass an object to a method, we just call the method by passing the reference of the object we have created.

So the correct answer is : A reference to an Object.
