How to Become a Proficient Java Programmer?0:39
So let's start with basic questions such as: What makes a programmer Proficient? Why should people strive to become proficient at their craft? Well! there could be too many answers fo the above question. But I will cover the most obvious ones below.

First, being a proficient Java developer doesn't mean that one has to write every line of code from scratch. One can use open-source or third-party libraries/frameworks for their development.

By proficiency, we mean not only how good your coding skills are but also the knowledge of how best to implement them using java programming language, its Frameworks, and Libraries. There is always a better way of doing it with java.

A proficient programmer is not restricted to a specific area of expertise, but he/she knows it all! That means they have good knowledge of their chosen coding language and its frameworks. Furthermore, one should be aware of the latest features added in Java, i.e., lambda expressions, functional interfaces, and streams APIs.

Apart from knowing his programming language inside out, a proficient programmer also has a good understanding of computer science fundamentals such as design patterns, and code maintainability and should be able to write clean codes.

Notes: Course Overview1:16
In this section, you learn about what will be covered in this course.

What is Java?1:53
Java is a modern, high-level, general purpose programming language to build applications for:
desktop,
mobile (including Google Android),
embedded systems,
data processing,
games,
web,
distributed enterprise applications,
IoT devices (like Raspberry Pi),
and many more...
The java platform is used in a wide variety of computing platforms, from embedded devices and mobile phones to enterprise servers and advanced computers.
It was designed as an object-oriented programming (OOP) language, but currently, it supports multiple programming paradigms (not just OOP); we will learn more about this later in this course.
It is a great programming language to learn as it is designed to work on almost all platforms. Java is a technology that allows code to be written once and run on multiple platforms.
More than 3 billion devices run java applications.
Notes: What is Java?1:58
Notes: Overview of Java1:01
In this section, you will get an overview about Java
History of Java1:01
History of Java
Java is a programming language and computing platform first released by Sun Microsystems in 1995. It was designed in the early 1990s by James Gosling, a computer scientist from Sun Microsystems; later, it was acquired by Oracle, so currently, it is owned by Oracle.

The initial goal was to create a modern object-oriented language that takes advantage of being platform-independent. This means the same program can be run on various computers without any change, even if these are based on different hardware platforms and operating systems.
Why Java?1:12
Why Java?
Java is a good choice for general-purpose programming, especially when cross-platform compatibility is needed.
Java has the following characteristics:
Secure and platform-independent - It is secure and platform-independent so that you can run java programs on almost all kinds of computers and operating systems (including macOS, Linux, and Windows).
Portable, robust and dynamic - able to fit any application's needs. You only need to write the program once to be able to run it on several platforms (Write Once, Run Anywhere). This makes it portable.
Java has a huge community of around 8 million developers worldwide. It is one of the most popular programming languages.
Java’s portability makes it a popular choice for server computers, which store data for other systems and software programs.
The main disadvantage of using Java is that it can be relatively slow compared to other languages, such as C or C++. This is especially true on platforms requiring bytecode interpretation, as with most smartphones and tablets.
Key characteristics of Java
Some key characteristics include:
Java is a compiled language. This means that the program is first written in a human-readable form, called source code, and then converted into a machine-readable form, called bytecode. A Java Virtual Machine (JVM) can run bytecode on any computer.
-Java is an object-oriented language. Everything in Java is an object, including numbers and functions.
-Java is a platform-independent language. This means that the same program can be run on various computers without any change, even if these computers are based on different hardware platforms and operating systems.
Java Editions1:01
Java Platform
Java is not only a programming language but also a development platform. It derives much of its syntax from C and C++ but has simpler syntax and provides fewer low-level facilities.
Java Editions
The Java platform is used in various computing platforms, from embedded devices and mobile phones to enterprise servers and advanced computers.
The Java programming language was initially designed for interactive television, but it was too advanced for the digital cable television industry at the time. It has since become one of the most popular programming languages, particularly for client-server web applications. For this reason, platforms (sets of APIs) are being created to support the language.
Java Platform, Standard Edition (Java SE) – core Java Platform and libraries. This is a set of APIs that can be used by developers to create applications for desktop computers and servers. Various elements of the Java SE platform are available under different licenses. The main license is the GNU General Public License.
Java Embedded – a subset of Java SE designed for embedded devices (like smart cards). This was earlier known as Java Platform, Micro Edition (ME), which allows for creating applications that can run on various devices. This contains a java virtual machine implementation for devices with limited memory and a reduced instruction set, such as mobile phones or car navigation systems.
Java Platform, Enterprise Edition (Java EE) – used for building web-based applications for large-scale or multi-tier architectures. Java EE usually uses XML for describing various resources (components, data sources, etc.) used by the application. These resources are packaged into a file with a .ear extension and deployed to an application server that reads these resources at runtime and provides the necessary backend functionality.
