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 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.
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.
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.
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.
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.
This Java String Array article explains how to Declare, Initialize, and Create String Arrays in Java and various conversions that may be performed on String Array. In Java, arrays are a common data structure for storing many data types, ranging from elementary to user-defined.
The two most significant data structures in Java are Array and List. We'll learn how to convert a Java Array to a List in this section. We've also written Java applications that use several Java techniques to turn an Array into a List.
When a user refers to a variable that hasn't been declared in the application, the "can't find symbol" error occurs. To put it another way, the compiler isn't aware of the variable's declaration. For example:
