Learn Java Programming from Java Basics to Advanced Java

Explore Java basics by learning about data types and variables, including integers, doubles, and strings, and understand the main function as the program's starting point.

Run a Java program and view results in the output window. Use System.out.print to display strings, variables, and numbers in the console, showing how the main function executes.

Learn to capture user input in Java by using the scanner class, creating a scanner object, and reading a name (string) and age (integer) to display results.

Learn how arrays store multiple values in a single sequence with zero-based indices, how size determines memory blocks, and why over-sizing wastes blocks when array capacity exceeds usage.

Learn to declare and initialize arrays in Java, using int or string types, set a fixed size with new, assign values by index from zero, and print with System.out.println.

Learn to use the for loop in Java to repeat tasks, define start and end conditions, control updates, and print values from start to finish.

Explore how the while loop uses a condition to control execution, printing count values from 30 down to 1 and decrementing until zero to avoid an infinite loop.

This session demonstrates an interview question by coding a while loop with a true condition, resulting in an infinite loop that prints Apple until manually terminated.

Explore exception handling with a practical example of dividing numbers, demonstrating try-catch blocks, handling divide-by-zero errors, and continuing program execution after exceptions.

Learn about exception types in programming, distinguishing a generic catch-all exception from specific ones such as dividing by zero, and how to tailor error handling to different scenarios.

Explore the finally block in Java’s try-catch-finally, which executes regardless of exceptions, enabling guaranteed cleanup such as ending a program or removing a view.

Learn how functions act as processing units that take inputs, perform operations such as sum or factorial, and return outputs with defined arguments, return types, and a body inside braces.

Understand variable scope in Java by seeing how a local variable inside main is accessible only within its braces, and how moving it to a class enlarges accessibility across methods.

Explore how class and object form the blueprint of object oriented programming, using real-world examples like buildings and car models to show properties and functions.

Build a Java class for a person in Eclipse to learn object oriented programming, including variables, methods like eat and walk, and getters such as get name and get age.

Create objects from the person class using the new keyword and constructors to set properties like name and height, and learn to call methods with the dot operator.

Explore how primitive values and variables go on the stack, how object instances reside in the heap with their references on the stack, and how memory is freed on exit.

Learn how inheritance in object oriented programming lets Ford, Honda, and Toyota automatically acquire properties and functions from the car base class, avoiding code duplication.

Master java inheritance by extending a person class into a student class, reuse properties like name, gender, height, and methods, and navigate constructors with super, default, and multiple-argument forms.

Explore polymorphism in object-oriented programming by modeling a shape base class and derived triangle, rectangle, and square classes that each implement their own calculate area formula.

Learn polymorphism in Java by overriding the area method in shape, rectangle, and triangle, illustrating inheritance and shape-specific area calculations.

Explore the difference between overloading and overriding in Java, using inheritance examples where a subclass overrides a parent function and other methods are overloaded with different parameters.

Explore abstraction and interfaces by comparing a car's brake, start button, and accelerator to Java concepts; learn how interfaces hide complex implementation while exposing essential actions.

Discover how abstract classes and interfaces enable abstraction in Java, why abstract classes cannot be instantiated, how inheritance and interface implementation work, car examples, and differences between them.

Learn how abstract classes differ from interfaces, implement abstract and normal methods with default bodies, and extend an abstract car class to define BMW behavior.

Learn the abstraction concept by hiding area calculations for shapes like rectangle and triangle behind a single area function, so callers need only use the function name and ignore implementation.
