Question
You have a class Container that, like all other Java classes, derives from java.lang.Object:package com.skillsoft.test;public class Container { public Object myValue = new Object(); public void printMyValue(){ System.out.println(myValue); }}You have a child class BooleanContainer :package com.skillsoft.test;public class BooleanContainer extends Container { public boolean myValue = true;}Then you execute the following snippet of code:Object myContainer = (Container) new BooleanContainer();System.out.println(myContainer.getClass());What is returned by this snippet of code?Instruction: Choose the option that best answers the question. Answer Choicesclass java.lang.Stringclass java.lang.Objectclass com.skillsoft.test.Containerclass com.skillsoft.test.BooleanContainer
Solution
The correct answer is class com.skillsoft.test.BooleanContainer.
Here's why:
The code snippet creates a new instance of BooleanContainer and then casts it to its superclass, Container. However, the actual object type of myContainer is still BooleanContainer.
When you call getClass() on myContainer, it returns the runtime class of the object, which is BooleanContainer.
So, the output of the code snippet will be class com.skillsoft.test.BooleanContainer.
