Complete Java Programming

Explore Java internal features and program internals, from writing dot Java to compiling with Java C, generating dot class bytecode loaded by a class loader, verified and interpreted at runtime.

Learn to set up the Java path with temporary and permanent options using the command prompt and environment variables, and understand when JDK bin directory does not require a path.

Explore the roles of the JVM, JRE, and JDK, including how the Java virtual machine executes bytecode, provides runtime and development tools, and integrates libraries.

Create a new class and explore Java operators, including unary, arithmetic, relational, logical, shift, ternary, and assignment, with practical code examples.

Explore Java arithmetic operators, including addition, subtraction, multiplication, division, and modulus, then apply expressions with order of operations, and learn left and right shift and bitwise and logical operators.

Master logical and, bitwise and, and understand logical and vs or with practical Java examples. Explore the ternary and assignment operators, including short values and type casting nuances.

Explore Java control statements through if else examples that determine voting eligibility by age and identify leap years using modulus tests for 4, 100, and 400.

Learn how to implement a Java switch statement with cases and breaks, then use nested for loops to print a pyramid pattern with System.out.println.

Explore the enhanced for loop, while loop, and do-while loop, along with break and continue statements, using array examples to illustrate printing and control flow in Java.

Explore multi-threading concepts, compare thread and process approaches, and learn how to create threads by extending the thread class or implementing runnable while understanding the thread life cycle.

Explore how the Java thread scheduler manages execution, using sleep and yield, and compare extending Thread versus implementing Runnable to create and start multiple threads.

Explore how Java strings are objects that represent a sequence of characters, including string, string buffer, and string builder. Create strings with literals or the new keyword; strings are immutable.

Explore immutable strings in Java, including string literals, the string pool, and how concatenation, equals, and compareTo affect memory and equality.

Explore Java regular expressions, including the pattern and matcher classes, importing java.util.regex, and three ways to check string matches using pattern.compile, matcher, and pattern.matches.

Explore how to use Java's pattern.matches for regular expressions, test strings with various characters, and understand true or false results through practical examples.

Explore how inheritance enables code reuse in Java by extending an employee class with a programmer class, accessing salary and bonus, illustrating is-a relationships.

Explore single, multi-level, and hierarchical inheritance in Java, illustrated by an animal-dog example with eat and bark methods demonstrated in a main class for complete Java programming course.

Discover how multiple inheritance and hierarchical inheritance work in Java through an animal, dog, and baby dog hierarchy, printing barking and eating behaviors and illustrating single, multi-level, and hierarchical patterns.

Explore aggregation in Java through an employee and address example that demonstrates a has a relationship, with parameterized constructors, a display method, and a main method to run the example.
