Java and Continuous Integration: Jenkins and More – PL Courses

Continuous Integration (CI) is a software development practice that promotes frequent integration of team members' work, leading to reduced errors and faster software development. With CI, developers can easily detect and locate errors, avoiding integration conflicts and delays in software release. By integrating changes regularly, teams can develop cohesive software more rapidly.

Java and Maven: Build Automation – PL Courses

Build automation in Java is essential for efficient software development. By automating tasks like compiling code, managing dependencies, and running tests, build automation tools eliminate errors and save time. Tools like Apache Ant, Maven, and Gradle offer advanced features for seamless Java build automation. Discover more about modern build automation tools in Java.

Java Inheritance: Basics and Examples – PL Courses

Inheritance in Java allows classes to inherit properties and methods from another class using the 'extends' keyword. This promotes code reusability and creates a hierarchical relationship between classes, supporting the concept of polymorphism. Learn how inheritance works in Java with a simple example and explore its types in real-world programming scenarios.

Java Operators: Types and Usage – PL Courses

Learn about the fundamental arithmetic operators in Java and how they can be used to perform basic mathematical operations on different data types. Discover the commonly used operators like addition, subtraction, multiplication, division, and modulus, along with compound assignment operators for concise code writing. Mastering these operators especially important for Java developers.

Java 8 Features: Streams, Lambdas, and More

Java 8, released in 2014, brought several new features to increase developer productivity and improve Java application performance. Notable additions include lambda expressions for cleaner code, a new Streams API for functional data processing, and a new Date and Time API. Java 8 also enhanced the concurrency API, improved garbage collection, and JavaScript runtime. Overall, Java 8 remains widely used due to its powerful features and performance improvements.

Java Servlets: Building Web Applications

Java Servlets are server-side Java programs that handle client requests and generate dynamic web content. They are essential for Java-based web applications, extending the capabilities of servers. Servlets can respond to any request, allowing for the creation of dynamic web content. They are platform-independent and can generate HTML pages dynamically. Servlets can handle complex tasks and work in combination with other Java technologies to create powerful web applications. Learn more about the key components and functionality of Java Servlets and best practices for building web applications using this technology.

Java and Event-Driven Architecture – PL Courses

Event-Driven Architecture (EDA) is a design paradigm that revolves around events and their reactions. It involves event producers generating events and publishing them to channels, while event consumers subscribe to these channels and respond to the events. EDA provides flexibility and scalability by decoupling producers and consumers. This approach is particularly useful for distributed systems and microservices.

Java and Text Mining: Analyzing Text Data – PL Courses

Text mining, also known as text data mining or text analytics, is the process of deriving high-quality information from text. It involves extracting information from written resources using natural language processing and analytical methods. This process transforms unstructured text into structured data suitable for analysis. Java, with its robust libraries and frameworks, provides an excellent platform for building text mining applications that can uncover hidden insights and support decision-making processes in various industries.

Java Performance Tuning: Tips and Techniques – PL Courses

Learn how to identify and optimize Java performance bottlenecks. Key areas to consider include garbage collection, memory leaks, CPU usage, I/O operations, and synchronization. Profiling tools like JVisualVM, YourKit, or JProfiler can help diagnose bottlenecks. Remember to measure and analyze performance before making changes to avoid unnecessary complexity.

Tomasz Tunguz: From Java engineer to investor in eight unicorns

Ben talks with venture capitalist Tomasz Tunguz about his path from Java engineer to Google product manager and finally to author and investor. They cover why lower data storage costs and improved database performance are driving a new wave of innovation, how LLMs learn by doing, and how companies (and investors) should respond to uncertain economic conditions.
