Java Programming for Complete Beginners
Java is one of the most popular programming languages. Java offers both object-oriented and functional programming features. We take a hands-on approach using a combination of jshell and eclipse as an ide to demonstrate over 200 java coding exercises, puzzles, and code examples. This course does not assume any prior programming (beginner) or java experience. If you’ve never programmed a computer before, or if you already have some experience with another programming language and want to learn java quickly, this course is perfect for you.
In over 250 steps, we explore the most important features of the java programming language, including:
Fundamentals of java programming – expressions, variables, and print output
Java operators – java assignment operator, relational and logical operators, short-circuit operators
Java conditions and if statement
Methods – parameters, arguments, and return values
Object oriented programming – class, object, state and behavior
Oops fundamentals – encapsulation, abstraction, inheritance and polymorphism
Basics of java data types – casting, operators and more
Java built-in classes – bigdecimal, string, java wrapper classes
Conditions with java – if else statement, nested if else, java switch statement, java ternary operator
Loops – for loop, while loop in java, do while loop, break and continue
Immutability of java wrapper, string and bigdecimal classes
Java dates – introduction to localdate, localtime and localdatetime

Introduction to variable arguments
Fundamentals of class design – class, object, state, and behavior. Decision-making state and builders.
Understand the composition and inheritance of objects
Java abstract class and interfaces. Introduction to polymorphism.
Java collections – list interface (arraylist, linkedlist and vector), set interface (hashset, linkedhashset and treeset), queue interface (priorityqueue) and map interface (hashmap, hashtable, linkedhashmap and treemap () – compare, contrast and choose
Generics – why do we need generics? Restrictions with extends and generic methods, wildcards – upper limit and lower limit.
Functional programming – lambda expression, flow and operations on a flow (intermediate operations – sort, distinguish, filter, map and terminal operations – max, min, collect in list), functional interfaces – predicate interface, consumer interface, user interface function for mapping, method references – static and instance methods
Introduction to threads and multi-threading – need for threads
Threads implementation – extending the thread class and implementing the executable interface
States of a thread and communication between threads
Introduction to the executor service – customization of the number of active threads. Return a future, invokeall and invokeany
Introduction to exception handling – your thinking process while handling exceptions. Try, catch and finally. Exception hierarchy – checked exceptions vs. Unchecked exceptions. Throw an exception. Creating and throwing a custom exception – currencydonotmatchexception. Try with resources – new feature in java 7.
List the files and folders in the directory with the file list method, file browse method, and read and write search methods from file.
Java In-Depth: Become a Complete Java Engineer!
This master’s course has been meticulously developed for over 5 years and has over 50,000 students from over 150 countries, ranging from beginners to experienced Java professionals. Large companies like Cognizant, Intel, PayPal, Pinterest, Wipro actively use this course to improve the skills of their employees. It has consistently been rated one of Udemy’s Top 3 Paid Java Courses and has helped many students start their careers as “confident” Java programmers. To ensure that you are proficient in the Java language, the course has been developed to be very comprehensive, covering most of the functionality of the Java language and discussing in great depth. To make sure you’re industry-ready and can write well-designed professional code, tons of best practices and design principles are explained and demonstrated in the code.
This course begins by providing an overview of Java covering everything from originating Java to installing Java and writing your first Java program. Even the most basic concepts like compilation and interpretation are explained. All other topics are covered in depth from the basics of language, object-oriented concepts and design, internal JVM components, exceptions, I / O, collections framework, generics, multi- threading, databases, nested classes, enumerations and functional style programming via Java 8 constructs like lambdas and streams. You will also learn about database design and implementation (SQL) and how to interact with them from Java programs (via JDBC). The course also gives a very good introduction to Java EE technologies like JSP, Servlets and JSTL, which help in project implementation. Finally, an excellent Eclipse IDE tutorial is also included, which teaches you how to use Eclipse in a professional manner to write, debug, and even effectively test Java programs using the JUnit framework.
Each lecture has been very carefully designed to explain the motivation behind each concept. Each concept is clearly explained with thoughtful examples and illustrations and is demonstrated in the code. Object oriented concepts such as inheritance and polymorphism are explained through a real world case study, which is also implemented as part of the course project. Several stimulating coding exercises and quizzes are included to reinforce what you have learned. Your solutions for coding exercises are also self-assessed to help you instantly know whether the solution is correct or not.
The course project involves the creation of a bookmark-making web application that helps users add bookmarks to items such as books, movies, and web pages, and that is built up gradually as new concepts are introduced. The project is instructor-led and is implemented using professional coding conventions and best practices. It follows a good object-oriented design, incorporates the MVC architectural model and also uses the test-driven development (TDD) methodology. The Java EE stack including technologies such as servlets, JSP, and JSTL is used to build the application with MySQL as the database and Apache Tomcat as the web server. Some parts of the project use advanced multi-threading features.Finally, the course also teaches several best practices and design principles that are essential for writing well-designed code.
