Define a Java method with public access, a return type, and get total marks signature. Show returning primitives or objects, such as int or a student class, with camelCase.

Create an object of a class with the new keyword, call get total marks on s1 using 5 and 10 to obtain 15, and note main method and default constructor.

Constructors in Java are special functions named like the class, with no return type. They initialize data members when creating objects with new and illustrate the default constructor concept.

Create a Java school project from scratch by modeling student and teacher classes with properties and constructors, using arrays and strings, and exposing methods to display info and total marks.

Explore how Java packages group classes, use reverse domain names for meaningful package nomenclature, and control access with public versus default modifiers to enable cross-package use.

Explain static versus non-static members and methods in Java, showing how static variables share a single copy across all objects and can be accessed via class name.

Explore the magic method public static void main as the Java entry point the JVM relies on, using a string array of arguments.

Explains how the this keyword refers to the calling object and enables method chaining in Java, using constructor initialization and a login form example to illustrate fluent APIs.

Explore the string data type in Java as a class, create instances with new or literals, and use length, charAt, substring, and lowercase/uppercase methods with zero-based indices.

Learn arrays in Java as objects that store multiple values of the same type, using the declare, construct, initialize three-stage process with int and string examples.

Explore arithmetic operators in java, including plus, minus, multiplication, and division, with examples using x and y, and learn postfix and prefix increment and decrement operators.

Explore assignment and compound assignment operators in Java, using variables to show m += y, z -= y, z *= y, and z /= y with printed results.

Discover relational operators in Java, enabling binary decisions by comparing ten and twenty, using equals, not equals, greater than or equal to, and less than or equal to in conditionals.

Explore how to use logical operators in Java, including and (&&), or (||), and not (!) to combine conditional statements and control outcomes like printing yes or no.

Explore how Java access modifiers govern visibility for classes, variables, and methods. Learn public, default, protected, and private, and how each affects package and subclass access.

Learn how public and default (package-private) class modifiers control visibility across Java packages, including how public classes are accessible anywhere and default classes stay within their package.

Explore public access modifiers for methods and variables in Java, covering intra- and inter-package access, dot and non-dot usage, and inheritance through subclassing.

Explore the default access modifier in Java, restricting members to the package, accessible within the same package via names or inheritance, but not from other packages.

Discover how the protected modifier in Java combines package access and inheritance to control visibility; access within the same package or through subclasses, while restricting outside non-subclass access.

Learn how the private modifier restricts visibility to the declaring class, keeping private members and methods inaccessible from other classes, packages, or subclasses.

Explore the differences between instance, static, and local variables in Java, noting that instance variables have default values while local variables do not.

Explore how instance variables in Java are declared inside a class, hold default values, and exist as separate copies for every object, illustrating with practical examples.

Explore static variables in Java as class variables shared by all instances. Access them via the class name or any object, demonstrating shared state and default values when uninitialized.

Local variables are defined inside methods and must be initialized before use, or Java reports an error. Their scope is limited to the method, unlike instance or static variables.

Master the for loop in Java, including initialization, condition, and update, and learn array iteration and the enhanced for loop for clean code.

Discover the enhanced for loop in Java for iterating over arrays and collections to access values, not indices. Use the classical for loop when you need index positions.

Explore the while loop in Java, its syntax and how it differs from a for loop, including initialization, condition, and updating inside the body.

Illustrate the do-while loop in Java, compare it with the while loop, and show how do-while guarantees at least one execution by checking the condition after the body.

Master if-else statements in Java by exploring single and multi-condition checks, else-if chains, and practical examples that print outcomes based on value ranges.

Explore how to use the switch statement in Java to evaluate a variable with cases, a default case, and break, compare specific values, and contrast with if-else for ranges.

Explore abstract classes and methods in Java, showing how an abstract class can contain concrete methods, how to implement abstract methods in a subclass, and why instantiation is not allowed.

Explore how interfaces enforce 100% abstraction in Java, using the implements keyword to let a class implement interfaces, such as Chrome and Firefox implementing a browser interface for Selenium WebDriver.

Explore object oriented programming in java by modeling entities as classes and objects with state and behavior. Learn encapsulation and data hiding, abstraction via abstract classes and interfaces, inheritance, polymorphism.

Learn encapsulation in Java by data hiding with private variables and exposing controlled access through public getters and setters to ensure safe object state.

Explore abstraction in Java by data hiding and detail hiding, using abstract classes and interfaces to let you call methods like walk and eat without exposing implementations.

Explains inheritance in Java, enabling code reusability and extensibility through a parent car class and child classes using extends and super, demonstrating drive and play music behaviors.

Explore polymorphism in Java, where a single entity takes many forms through overloading and overriding, with parent and child classes and with abstract classes, interfaces, and inheritance.

Explore how abstract classes enable polymorphism by using an animal base class extended by dog and cat, where a single reference can behave as either dog or cat.

Explore how interfaces enable polymorphism in Java by implementing a browser interface with chrome and firefox classes; a single reference can act as either, invoking console and user interface methods.

Investigate how inheritance enables polymorphism in Java by using a car base class with Maruti and Suzuki subclasses, and a base reference that invokes overridden drive methods.
