| 4 | +### Introduction |
| 5 | + |
| 6 | +We love Programming. Our aim with this course is to create a love for Programming. |
| 7 | + |
| 8 | +Java is one of the most popular programming languages. Java offers both object oriented and functional programming features. |
| 9 | + |
| 10 | +We take an hands-on approach using a combination of JShell(An awesome new feature in Java 9) and Eclipse as an IDE to illustrate more than 200 Java Coding Exercises, Puzzles and Code Examples. |
| 11 | + |
| 12 | +In more than 250 Steps, we explore the most important Java Programming Language Features |
| 13 | +- Basics of Java Programming - Expressions, Variables and Printing Output |
| 14 | +- Java Operators - Java Assignment Operator, Relational and Logical Operators, Short Circuit Operators |

| 32 | +- Generics - Why do we need Generics? Restrictions with extends and Generic Methods, WildCards - Upper Bound and Lower Bound. |
| 33 | +- Functional Programming - Lambda Expression, Stream and Operations on a Stream (Intermediate Operations - Sort, Distinct, Filter, Map and Terminal Operations - max, min, collect to List), Functional Interfaces - Predicate Interface,Consumer Interface, Function Inteface for Mapping, Method References - static and instance methods |
| 34 | +- Introduction to Threads and MultiThreading - Need for Threads |
| 35 | +- Implementing Threads - Extending Thread Class and Implementing Runnable Interface |
| 36 | +- States of a Thread and Communication between Threads |
| 37 | +- Introduction to Executor Service - Customizing number of Active Threads. Returning a Future, invokeAll and invokeAny |
| 38 | +- Introduction to Exception Handling - Your Thought Process during Exception Handling. try, catch and finally. Exception Hierarchy - Checked Exceptions vs Unchecked Exceptions. Throwing an Exception. Creating and Throwing a Custom Exception - CurrenciesDoNotMatchException. Try with Resources - New Feature in Java 7. |
