Midland Healthcare & Research Center Interview Questions and Answers

The code checks if a and b are equal. If not, it returns their sum.

• The '==' operator checks for value equality, while the 'equals()' method checks for object equality.

• In this case, since a and b are primitive types, the '==' operator is used.

• If a and b are equal, the code returns a. Otherwise, it checks if they are equal as objects using 'equals()'.

• If they are equal as objects, it returns b. Otherwise, it returns the sum of a and b.

Private, public, and protected are access modifiers in object-oriented programming.

• Private members can only be accessed within the same class.

• Public members can be accessed from anywhere.

• Protected members can be accessed within the same class and its subclasses.

• Access modifiers help control the visibility and accessibility of class members.

• Example: class Person { private String name; public int age; protected String address; }

Explaining the Def function with a condition and summing up numbers greater than 2.

• The Def function checks if the input number is greater than 2.

• If it is, the number is added to the sum variable.

• The final sum is returned as output.

• For example, Def(1, 2, 3, 4) would return 7 (3+4).

Ooops is not a technical term. Abstract refers to a concept or idea rather than a specific instance.

• Ooops is not a technical term used in software development.

• Abstract refers to a concept or idea rather than a specific instance.

• In object-oriented programming, abstract classes and methods are used to define a common interface for a group of related classes.

• For example, a Shape class can be abstract and have methods like draw() and area() which are implemented by its subclasses...read more

A class is a blueprint for creating objects. An object is an instance of a class.

• A class is a template or blueprint that defines the properties and methods of an object

• An object is an instance of a class that has its own state and behavior

• Classes and objects are fundamental concepts in object-oriented programming

• Example: A class 'Car' can have properties like 'color', 'model', and methods like 'start', 'stop'

• Example: An object 'myCar' can be created from the 'Car' class with ...read more
