certainly! below is an informative tutorial focused on day 2 of a core java full stack course, which is typically centered around foundational java concepts. this tutorial will cover essential topics such as object-oriented programming (oop) principles, classes and objects, methods, and basic exception handling in java. at the end, i'll provide code examples to illustrate these concepts.

day 2: core java concepts

1. object-oriented programming (oop) principles

java is an object-oriented programming language, which means it is based on the concepts of 'objects'. here are the four main principles of oop:

**encapsulation**: bundling the data (variables) and methods (functions) that operate on the data into a single unit called a class. it restricts direct access to some of the object's components.

**inheritance**: a mechanism where one class can inherit fields and methods from another class. this promotes code reusability.

**polymorphism**: the ability of different classes to be treated as instances of the same class through a common interface. it allows methods to do different things based on the object it is acting upon.

**abstraction**: hiding complex implementation details and showing only the essential features of the object.

2. classes and objects

**class**: a blueprint for creating objects. it defines a datatype by bundling data and methods that work on the data.

**object**: an instance of a class. it represents a specific implementation of the class.

*example: creating a class and object*



3. methods

methods are blocks of code that perform a specific task. they can take inputs (parameters) and can return a value.

*example: method overloading*



4. exception handling

exception handling in java is a powerful mechanism to handle runtime errors, allowing the normal flow of the application to be maintained.

*example: try-catch block*
