Can I learn Selenium without knowing Java?

This question concerns many professionals who don’t actually understand the core technology and want to develop their career in Selenium Automation field. The term coding is a bit intimidating to non-programmers to even start with something like automation. People think that non-programmers can't excel at automation, but that's just in the mind. Many worthy and capable manual testers shy away from Selenium, simply assuming that it requires some special skills.

Selenium scripts are designed in multiple languages ​​such as Python, Ruby, C#, JavaScript and Java is one of them among them. Knowing the popularity and future prospects of Java, I am now more inclined towards it. Although Python is also very popular now.

We will not deny that learning Selenium requires basic concepts of Java. Let’s see how much you need to know about Java programming.

Things to remember before you start learning Basic Java -

• Learn it with a mindset, without any non-coder baggage.
• Basic logic construction
• Implementing logic concepts

The following is the basic knowledge of Java, which must be adhered to when learning Selenium-

• Java Programming Structure - A Java program consists of various parts such as a package part where all the imported packages are mentioned. A package is a collection of classes, interfaces, and subpackages. The default in java is java lang. Packages are imported by every program. We need to import the rest of the packages as required. Then comes the class section, where objects are defined and methods are called. Then comes the main method section, which is the starting point of the program. Methods contain data type declarations and executable statements.

• Understanding Objects and Classes (OOP - Object Oriented Approach) - OOPS concepts are the backbone of Java. It consists of real-world entities such as abstraction, inheritance, encapsulation, polymorphism, etc., which are ways to reuse functionality where security needs to be maintained. In this way, the data and function are bound together so that it cannot be accessed by any other part of the code except that function.

• #Class - A class is a template used to create objects and define object data types and methods. An object is an instance of a class with specific state and behavior.

• Variables - They store the values ​​that the program needs to do its job. So they are basically memory locations. It has many data types that must be declared before use. The value of a variable can be changed at any time in the program.

• Methods - These are like functions created to perform a specific task. It only runs when called.

• Inheritance - It is a part of OOPS that allows one class to inherit the functionality of another class.

• Abstraction - Hiding unnecessary details from the outside world and providing only essential details is part of abstraction.

• Encapsulation - Encapsulation means wrapping code and data into a unit to protect the inner workings of an object from outside influences. For example, a calculator.

• Interface - Unlike classes that are inherited by other classes, interfaces are implemented or extended by other classes. It is used to implement multiple inheritance in programs. All methods in an interface are implicitly public and abstract. It is used to achieve complete abstraction.

• Array - It is a group of similar variables with contiguous memory locations. Control statements - They support decision making, branching and looping such as if-then-else, while loop, for loop.

• Collections - Whenever data is dynamic, collections are used. It allows adding elements, removing elements.

• Polymorphism (overloading/overriding) - By polymorphism, we can say that a specific operation can be performed by multiple execution method. There are two types of polymorphism - compile-time polymorphism and run-time polymorphism. In order to implement inheritance, polymorphism is required. It helps programmers reuse code, classes, and methods that are written, tested, and implemented once.

• FileHandling - It allows us to create, read, update and delete files stored on the local file system. Java l/o (input and output) is used to process input and generate output.

• ExceptionHandling - Exception handling plays a vital role in handling runtime errors so that the normal flow of the application can be maintained. Various exceptions such as FileNotFound Exception and IOEXception are used to handle it. By handling these exceptions, we can provide correct error messages instead of incomprehensible system-generated errors.

• Thread Basics - A thread is an independent execution path within the program. When multiple threads are running simultaneously in a program, multiple tasks are performed at one time. They provide maximum utilization of the CPU.
