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 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

Java Concurrency in Practice


by Brian Goetz, Tim Peierls, Joshua Bloch, Joseph Bowbeer, David Holmes and Doug Lea. As processors become faster and multiprocessor systems become less expensive, the need to leverage multithreading to achieve full utilization of hardware resources only increases the importance of being able to adapt to competition in a wide variety of applications. Applications. For many experienced java programmers, the competition remains a mystery. Developing, testing, and debugging multithreaded programs is extremely difficult because competitive risks do not manifest themselves consistently or reliably.
