Complete Java Programming Bootcamp: Learn to Code in Java

Learn java data types, including primitive types like byte, short, int, long, float, double, char, and boolean. Explore non-primitive types such as classes, interfaces, and arrays with practical examples.

Discover how to declare and initialize variables in Java, including integers and strings, print them with system.out.print and println, and declare multiple variables in one line.

Explore Java operators, including arithmetic, relational, logical, and bitwise operators, through practical examples that demonstrate math operations, comparisons, boolean logic, and bitwise manipulation.

Learn how Java uses conditional statements—if, else if, and switch—with practical examples classifying numbers as positive, negative, or zero and switching on days.

Master Java looping constructs by using for, while, and do-while loops to run repeated tasks and print sequences 1 to 5, 1 to 10, and 1 to 8.

Learn the basics of object oriented programming in java by defining a class and its object, a simple person with name and age, and a display method.

Explore the four core object oriented programming principles in Java: encapsulation, inheritance, polymorphism, and abstraction, through practical examples that highlight data protection, code reuse, dynamic behavior, and interface-driven design.

Learn to create and use classes and objects in Java, understand attributes and methods, and apply constructors to initialize objects and display values like car models.

Learn how constructors initialize Java objects with a car example and a display method, then explore calculator methods and access modifiers like public and private in a person example.

Explore data hiding and encapsulation in Java by using private fields, a salary setter with validation, and a getter to display employee data.

Learn how abstract classes provide a blueprint in Java, combining abstract and concrete methods, and how a subclass like dog implements the abstract sound method, while the class handles sleep.

Create and use custom exceptions in Java, explore how exception propagation transfers errors up the call stack, and implement try-catch handling in a banking example.

Explore Java collections by working with lists, sets, maps, and queues. Learn array list, hash sets, hash maps, and linked list queues with fifo behavior.

Explore sorting, searching, and iterating through Java collections. Learn to sort lists with Collections.sort, search elements in sets, and iterate map entries.

Explore lambda expressions and functional interfaces in Java, using a greeting example and a square calculator that returns values, demonstrated with five yielding 25.

Explore Java advanced sorting using custom comparators and multi-field sorting to order lists and objects, including sorting employees by name and age with comparator chaining.

Learn to read from and write to files in Java i/o, using file writer, buffered writer, and buffered reader with try-with-resources for output.txt.

Learn to write and read text files in Java using FileWriter, FileReader, and BufferedReader; handle exceptions, and run examples that write 'hello java program' to example.txt and read it back.

Learn how to serialize a Java object by converting it to a byte stream and saving it to a file using ObjectOutputStream, with a serializable person example.

Serialization saves an object to a byte stream for storage or transmission; deserialization restores it. A practical example uses a person object saved to a file.

Learn how java threads and concurrency enable multi-tasking and responsive applications using the thread class and runnable, while mastering thread life cycle and synchronization concepts.

Create and manage threads in Java using the thread class and the runnable interface to run tasks concurrently, start threads, and apply sleep delays.

Explore how java uses synchronized methods and blocks to coordinate threads, prevent race conditions, and safely update shared counters and bank balances in multi-threaded code.

Explore deadlock, race conditions, and thread safety in Java concurrent programming with practical examples that show deadlock, race condition timing, and synchronized thread safety.

Build a simple Java GUI application using Swing by creating a JFrame, adding a JPanel and a JButton, setting size and close behavior, and making the window visible.

Explore how to handle events in Swing by wiring an action listener to a button click to update a label, using JFrame, JButton, JLabel, and a flow layout.

Explore layout managers in Java Swing, including column and flow layouts for arranging components, and grid layout for a 2x2 grid of buttons that wrap on resize.

Learn how to connect Java applications to relational databases with JDBC, establish a connection using driver manager to a MySQL database, and execute queries with error handling.

Perform CRUD operations in Java using JDBC with a MySQL database, including inserting, querying, updating, and deleting employee data.

Learn to handle database exceptions in Java using JDBC, recover from connection failures, invalid queries, and timeouts, with SQL exception handling and error messages and codes.
