Channel Title: Learn Automation Online Channel Description: I am Arulprasath. I hail from a rural background and struggled a lot to get into IT industry. When I was a student I couldn't afford money for any training institutes. Wanted to give back to the society and help people by teaching IT courses for FREE. MONEY should never be a barrier for learning and guess what my videos will be free forever! One of my core strengths is teaching and I have started posting video tutorials in Tamil. All my videos are for absolute beginners and even if you don't know coding or anything related to programming, you can master it. As of now, all the videos are revolving around TESTING and related concepts. In future will cover other areas of Computer Science. Let's learn together! Let's grow together! Help me in creating a better Tech learning Tamil community. Cheers!

This method allows modules to provide users with “read-only” access to internal lists. Query operations on the returned list “read through” to the specified list, and attempts to modify the returned list, whether direct or via its iterator, result in an UnsupportedOperationException. The returned list will be serializable if the specified list is serializable. Similarly, the returned list will implement RandomAccess if the specified list does.

It does this by applying a binary operator to each element in the stream, where the first argument to the operator is the return value of the previous application and the second argument is the current stream element. Reduce functions takes Identity: The initial value of the reduction. This is the value that will be returned if the stream is empty. Accumulator: A binary operator that combines two values of type T into a single value of type T. Combiner: The combiner in the reduce() function is a binary operator that combines two values of type T into a single value of type T. It is used to accumulate the results of the reduction as the reduce() function iterates over the elements of the stream. The reduce() function works by first applying the accumulator to the identity value and the first element in the stream. It then applies the accumulator to the result of the previous application, the next element in the stream, and so on. This process continues until all the elements in the stream have been processed. The final result of the reduction is the return value of the last application of the accumulator. The reduce() function is a very powerful tool for combining and aggregating data in streams. It can be used to perform a variety of tasks, such as: Summing the elements of a stream Finding the maximum or minimum element in a stream Counting the elements in a stream Computing the average of the elements in a stream Creating a new collection from the elements of a stream Support by donating: --------------------------------- Google Pay UPI Id: arulprasath36@okicici Name: Arulprasath Email: arulprasath36@gmail.com Follow me on Linked In: https://www.linkedin.com/in/arulprasath-ranganathan-63b2b3154/ Instagram: im_arulprasath website: www.arulprasathranganathan.com You can watch my other tutorials ------------------------------------------------------ Selenium basics: http://bit.ly/2XtOt1F Selenium Advanced: http://bit.ly/2WYieZe TestNG Absolute Beginner Guide: http://bit.ly/2N6xgaM Data-driven framework: http://bit.ly/2WVjSFT Page Object Model: http://bit.ly/2IAXJZR Framework development using POM and Cucumber: https://rb.gy/fer4sw Keyword driven framework development: https://rb.gy/gosduk How to write XPath on our own: http://bit.ly/2KwMLql Must know Java concepts for Selenium: http://bit.ly/31Ro7G8 Selenium Interview Questions: http://bit.ly/2N6xu1F Java for Selenium Automation: http://bit.ly/2IylOAh Maven beginner guide: http://bit.ly/2Rsigm0 GitHub Absolute beginner Guide: http://bit.ly/2Kxdzqj REST Web services beginner guide: http://bit.ly/2N69rQq Cucumber absolute beginner guide: http://bit.ly/2X0lSBB Acceptance Testing (Fitnesse) beginner guide: http://bit.ly/2Y6oE55 Jenkins beginner guide: http://bit.ly/2X39fGb Jmeter beginner tutorials: https://bit.ly/32achqW Java programs for Interview: https://bit.ly/3AZ5u4M Frequently Asked Interview questions for testers: https://bit.ly/3xFfyhm Agile beginner tutorials: https://bit.ly/3khmT2z Jira beginner tutorials : https://bit.ly/2TZLE97 Rest Assured beginner tutorials: https://bit.ly/3i4lpGw Selenium Exceptions: https://bit.ly/36BpYCS Manual testing tutorials: https://rb.gy/htjdm4 Freshers Tips and Guidance: https://rb.gy/m97ze8 ISTQB Foundation level Videos: https://rb.gy/erkss9 Postman Absolute beginner Tutorials: https://rb.gy/u5hds6 Roadmap for Freshers and Professionals: https://rb.gy/vuhvap Complete Rest Assured Tutorials: https://rb.gy/3wgta9 </video> <video> Java8 | 57 | AllMatch function | Tamil Description: Stream allMatch(Predicate predicate) returns whether all elements of this stream match the provided predicate.

By using Optional, you can avoid NullPointerExceptions and make it clear to readers of your code that a value may not always be available. </video> <video> Java8 | 59 | Find First vs Find Any | Tamil Description: The findAny() method is a terminal operation, which means that it performs its action and returns a result immediately. It is also a non-deterministic operation, which means that the result is not guaranteed. In the above example, the result will be different each time the code is run. The findAny() method can be used in a variety of situations where you need to find a random element from a collection. For example, you could use it to choose a random lottery winner or a random product to promote. The findFirst() method in Java 8 is used to find the first element in a stream. It is a terminal operation, which means that it cannot be chained with any other intermediate or terminal operations. The findFirst() method takes a predicate as its argument, which is a functional interface that takes an element as input and returns a boolean value. The findFirst() method will return the first element in the stream for which the predicate returns true. </video> <video> Java8 | 68 | Collectors | To List | To set | To Collection | Tamil Description: Collectors.toList(): - This collector collects the elements of the stream into a list. Collectors.toSet(): - This collector collects the elements of the stream into a set. Collectors.toMap(Function, Function): - This collector collects the elements of the stream into a map, with the first function providing the key and the second function providing the value. Collectors.toMap(Function, Function, BinaryOperator): - This collector collects the elements of the stream into a map, with the first function providing the key, the second function providing the value, and the third function providing a function to resolve conflicts between duplicate keys. Collectors.summingDouble(): - This collector sums the values of the stream's elements. Collectors.counting(): - This collector counts the number of elements in the stream. Collectors.averagingDouble(): - This collector averages the values of the stream's elements. Collectors.minBy(Comparator): - This collector finds the minimum element in the stream, according to the specified comparator. Collectors.maxBy(Comparator): - This collector finds the maximum element in the stream, according to the specified comparator.

The reduce() function works by first applying the accumulator to the identity value and the first element in the stream. It then applies the accumulator to the result of the previous application, the next element in the stream, and so on. This process continues until all the elements in the stream have been processed. The final result of the reduction is the return value of the last application of the accumulator. The reduce() function is a very powerful tool for combining and aggregating data in streams. It can be used to perform a variety of tasks, such as: Summing the elements of a stream Finding the maximum or minimum element in a stream Counting the elements in a stream Computing the average of the elements in a stream Creating a new collection from the elements of a stream Support by donating: --------------------------------- Google Pay UPI Id: arulprasath36@okicici Name: Arulprasath Email: arulprasath36@gmail.com Follow me on Linked In: https://www.linkedin.com/in/arulprasath-ranganathan-63b2b3154/ Instagram: im_arulprasath website: www.arulprasathranganathan.com You can watch my other tutorials ------------------------------------------------------ Selenium basics: http://bit.ly/2XtOt1F Selenium Advanced: http://bit.ly/2WYieZe TestNG Absolute Beginner Guide: http://bit.ly/2N6xgaM Data-driven framework: http://bit.ly/2WVjSFT Page Object Model: http://bit.ly/2IAXJZR Framework development using POM and Cucumber: https://rb.gy/fer4sw Keyword driven framework development: https://rb.gy/gosduk How to write XPath on our own: http://bit.ly/2KwMLql Must know Java concepts for Selenium: http://bit.ly/31Ro7G8 Selenium Interview Questions: http://bit.ly/2N6xu1F Java for Selenium Automation: http://bit.ly/2IylOAh Maven beginner guide: http://bit.ly/2Rsigm0 GitHub Absolute beginner Guide: http://bit.ly/2Kxdzqj REST Web services beginner guide: http://bit.ly/2N69rQq Cucumber absolute beginner guide: http://bit.ly/2X0lSBB Acceptance Testing (Fitnesse) beginner guide: http://bit.ly/2Y6oE55 Jenkins beginner guide: http://bit.ly/2X39fGb Jmeter beginner tutorials: https://bit.ly/32achqW Java programs for Interview: https://bit.ly/3AZ5u4M Frequently Asked Interview questions for testers: https://bit.ly/3xFfyhm Agile beginner tutorials: https://bit.ly/3khmT2z Jira beginner tutorials : https://bit.ly/2TZLE97 Rest Assured beginner tutorials: https://bit.ly/3i4lpGw Selenium Exceptions: https://bit.ly/36BpYCS Manual testing tutorials: https://rb.gy/htjdm4 Freshers Tips and Guidance: https://rb.gy/m97ze8 ISTQB Foundation level Videos: https://rb.gy/erkss9 Postman Absolute beginner Tutorials: https://rb.gy/u5hds6 Roadmap for Freshers and Professionals: https://rb.gy/vuhvap Complete Rest Assured Tutorials: https://rb.gy/3wgta9 </video> <video> Java8 | 65 | Reduce function | When do we need a combiner | Tamil Description: The combiner in the reduce() function is a binary operator that combines two values of type T into a single value of type T. It is used to accumulate the results of the reduction as the reduce() function iterates over the elements of the stream. The combiner is typically a mathematical function, such as addition, subtraction, multiplication, or division. However, it can also be a more complex function, such as a function that merges two collections or a function that computes the average of two values. The combiner is a very important part of the reduce() function, as it determines how the elements of the stream are combined to produce the final result of the reduction.

Description

I am Arulprasath. I hail from a rural background and struggled a lot to get into IT industry. When I was a student I couldn't afford money for any training institutes. Wanted to give back to the society and help people by teaching IT courses for FREE. MONEY should never be a barrier for learning and guess what my videos will be free forever! One of my core strengths is teaching and I have started posting video tutorials in Tamil. All my videos are for absolute beginners and even if you don't know coding or anything related to programming, you can master it. As of now, all the videos are revolving around TESTING and related concepts. In future will cover other areas of Computer Science. Let's learn together! Let's grow together! Help me in creating a better Tech learning Tamil community. Cheers!
