Functional Interfaces

A functional interface in Java is an interface with exactly one abstract method, enabling lambda expressions and method references as implementations.

Java

Dynamic Method Dispatch

Runtime polymorphism mechanism where the JVM determines which method implementation to call based on the actual object type at runtime.

Java

Java Sorting Interfaces

Learn how Comparable and Comparator interfaces enable custom sorting of objects in Java by defining natural ordering and external comparison strategies.

Java

Java Custom Sorting

Use lambda expressions with Collections.sort() to create custom sorting logic for complex object comparisons

Java

Java Custom Annotations

Create custom annotations to add metadata to classes, methods, or fields, enabling powerful runtime or compile-time processing of code.

Java

Java Method References

Method references provide a shorthand syntax for lambda expressions that simply call an existing method, improving code readability and conciseness.

Java

Java Generics Basics

Learn how generics provide compile-time type safety and eliminate the need for explicit casting in Java collections and classes.

Java

Java Reflection Basics

Examine and manipulate class properties, methods, and constructors dynamically at runtime using Java's Reflection API

Java

Java Stream Filter

Use Stream's filter() method to selectively process elements based on a predicate, enabling efficient data filtering in collections.

Java

Java Stream Reduce

Use of reduce() method in Java Streams to perform a reduction operation on stream elements, combining them into a single result value.

Java

Java Autoboxing

Automatic conversion between primitive types and their corresponding wrapper classes in Java, simplifying code and reducing manual type casting

Java

Java Enhanced For-Loop

Simplified iteration syntax for arrays and collections, reducing boilerplate code and improving readability.

Java

Java Enum Basics

Enums in Java are special classes that represent a group of constants with fixed values, providing type safety and more robust code organization.

Java

Java Enum Methods

Explore how Java enums can have methods, constructors, and implement interfaces, making them more powerful than simple constant declarations.

Java

Java For-Each Loop

Simplified iteration over arrays or collections, reducing boilerplate code and improving readability of loops in Java.

Java

Method Overloading

Method overloading allows multiple methods with the same name but different parameter lists in the same class, enabling more flexible method definitions.

Java

Java Optional Usage

Explore how to use Java's Optional class to handle potential null values and prevent NullPointerExceptions with more elegant code.

Java

Java Stream API

Powerful functional programming feature introduced in Java 8 for processing collections with method chaining and lambda expressions.

Java

Java Stream Filtering

Learn how to use Stream API to filter collections based on specific conditions efficiently in Java

Java

Java Stream Map

Transform elements in a stream using the map() method, converting each element to another form without modifying the original collection.

Java

Java Synchronized Methods

Demonstrates thread synchronization in Java to prevent race conditions and ensure thread-safe access to shared resources.

Java

Try-Catch Blocks

Exception handling mechanism in Java that allows graceful error management by catching and handling potential runtime exceptions.
