Download Becoming the Master of Java

What you would learn in Becoming the Master of Java course?

This course will lead you through a journey of the basics of Java through the bytecodes and on to more advanced aspects of programming.

Learning the basics of Java programming will position you in a favorable position to learn other languages like C++ and Python.

Java's syntax Java was developed for similarity to the syntax of C++ programs, so if you're directly from a C++ world, you're halfway through learning this Java language! Similar to that, Python operates based on the idea that each kind of thing is represented by an object and thus closely matches the logic that the Java language is based on.

The course is designed in an incomplete alignment and in line with the Oracle site for learning Java, known as the dev dot Java website. I will guide you through each of the topics covered on the dev dot java website and provide extensive examples of how to understand.

One feature unique to this course is its frequent inspection of the bytecodes of classes. Bytecodes contain the code that the Java compiler "javac" provides, which can reveal hidden code that javac uses to complete a task. For instance, in the most current release of JDK (java development kit), String concatenation always transforms into creating the StringBuilder object in the background and then calling the "append" method. Understanding these behind-the-scenes principles will allow you to thoroughly learn your knowledge of the Java programming language and create effective code.

The subjects covered in this class are:

Part 1: Getting Started With Java

This section will introduce the website dev dot java and address concepts like "JAVA_HOME" and "CLASSPATH" environment variables. The idea behind CLASSPATH will be explained more in-depth later in section 9 when I go over the idea of Java "packages."

Section 2 The Literals and Primitives

This section is a complete beginner's guide to the Java feature set. Java language can support raw primitives and wrapper classes (also known as Boxed Primitive). I go over all the primitives that are supported, including short, byte long, and double.

Third Section: arrays

This section is specifically devoted to an array built that is available in Java. Java language permits primitive arrays as well as to object arrays. An array can be immediately created once the array is created. User-defined classes can't expand built-in arrays.

Section 4 local variable type inference

This section provides a brief overview of the "var" identifier introduced in the most recent versions of Java. "var" allows the compiler to determine the local variables' type without the programmer making any changes.

Section 5 Operators of Java

This section will introduce the basic idea of operators that Java's programming language allows. Math operators like "addition +", "subtraction -" and "modulus %" are discussed in depth. The essential idea that is "operator overloading" is also addressed.

Section 6 Expressions and Statements

This article provides a brief definition of an expression or a statement in Java. Operators and operands create expressions. Statements are composed of several expressions and are terminated with a semicolon ";"

Section 7 Constraint flow statement

This is a crucial section that focuses on the control flow assertions such as "if," "if-else," "while" loop, "for" loop, "switch expression," and "switch statement." The bytecode behind the scenes is also examined in each flow control construction.

Section 8: Introduction to OOP

This chapter introduces the basic ideas that are used in the field of object-oriented software. Java language was created with these principles in mind and is based on "inheritance," "abstraction," and "interfaces." Each "class" definition in java is implicitly derived its definition from the "Object" class that exists within the "java. lang" package. The concept of organizing Java into packages and using the fully-qualified names of the classes is covered in depth.

Section 9 Classifications and objects

This chapter explains the fundamental notions of object-oriented programming within its context in Java programming (syntax) and the distinctive capabilities that Java offers. We will discuss how Java deals with inheritance, polymorphism, and encapsulation and the distinction between objects' static and nonstatic states.

Section 10 advanced topics on classes and objects

This section delves into the functions of objects and classes that Java programming offers.

Section 11 The Introduction of Java Native Interface

This article explains the Foreign Function Interface (FFI) that the Java development kit comes with. JNI is seen by some as a challenging subject and is not often covered in courses and lectures. This chapter assumes that the student is familiar with C++ programming and how to build ".cpp" and ".h" files.

Section 12 The Introduction of Effective Java

This section introduces the most important book called "Effective Java" that every Java developer needs to be able to read. Each lecture corresponds with an element of the top practices of Java programming, which is covered within the text.

Section 13: Miscellaneous Topics

This section gives additional details on the Java programming language and the tools directly or indirectly connected to Java programming. Tools like GraalVM's own native image and Jupyter notebooks are reviewed.
