What is Pair Programming?

Pair Programming is a technique where two programmers work together on the same code using one workstation. The “driver” is the one who types the code on the keyboard, while the “navigator” is the one who checks the code for errors, typos, and readability. They also switch their roles every few minutes to share the work.

Define Inversion of Control (IoC).

IoC is a general term that software developers use to describe a pattern that helps separate components and layers in the system. It is mainly used with object-oriented programming. IoC means that objects or parts of a program are controlled by a framework or container instead of the objects themselves. IoC can be done using different methods such as service locator patterns, strategy design patterns, factory patterns, and dependency injection.

What is Dependency Injection?

Dependency Injection is a design pattern that implements IoC. It means that the container connects objects with other objects instead of the objects doing it themselves. It involves three kinds of classes.

Client class: This is the class that needs the service class.
Service class: This is the class that provides the service to the client class.
Injector class: This is the class that creates and injects the service class objects into the client class.

What is Continuous Integration?

CI is a practice where developers regularly merge code into a common repository to find issues early. CI process uses automatic tools that check the quality of new code before merging. Every check-in is verified by automated builds and tests.

What is multithreading and how is it used?

Multithreading is a technique that allows multiple threads of execution to run at the same time for optimal use of the CPU. It enables multiple threads to have their execution paths within a process, but share the resources of that process.
