: Deep dives into the 8 primitive types (byte, short, int, long, float, double, boolean, char). A common highlight in the notes is why Java is not 100% object-oriented (due to these primitives).
Evaluated at compile-time. The compiler forces you to handle them using try-catch or declare them with throws (e.g., IOException , ClassNotFoundException ).
Multithreading enables concurrent execution of two or more parts of a program for maximum CPU utilization. Creating Threads core java complete notes by durga sir top
// Traditional style Runnable r1 = new Runnable() public void run() System.out.println("Hello"); ; // Lambda style Runnable r2 = () -> System.out.println("Hello"); Use code with caution. Stream API
Holds the memory address of the JVM instruction currently executing for that specific thread. : Deep dives into the 8 primitive types
Introduction to Core Java Java remains a dominant force in enterprise software development. Mastering Core Java requires structured learning, clear mental models, and deep conceptual clarity. Durga Sir is highly regarded in the programming community for breaking down complex Java mechanisms into digestible, practical concepts.
Vector : A legacy, synchronized thread-safe alternative to ArrayList. The compiler forces you to handle them using
Multi-threading allows concurrent execution of two or more parts of a program for maximum utilization of CPU.
Here are some benefits of using Durga Sir's Core Java notes:
Here is a look at the fundamental building blocks covered in the first part of the notes. Mastering these topics is crucial for your journey as a Java developer.
Declared with the abstract keyword. They can have both abstract methods (without a body) and concrete methods. They can maintain an instance state.
