In Java, an interface is a reference type, similar to a class, that can contain only constants, method signatures, default methods, static methods, and nested types.

It allows developers to run Java code snippets directly from the command line, providing immediate feedback without the need for a full program or IDE setup. Ideal for quick testing, learning, and exploring APIs, JShell is a powerful tool for experimenting with Java code interactively.   𝑳𝒂𝒖𝒏𝒄𝒉𝒊𝒏𝒈 𝑱𝑺𝒉𝒆𝒍𝒍:     You can launch the JShell by simply typing `jshell` in your terminal or command prompt. This will open an interactive shell where you can start writing and executing Java code.   𝑲𝒆𝒚 𝑭𝒆𝒂𝒕𝒖𝒓𝒆𝒔 𝒐𝒇 𝑱𝑺𝒉𝒆𝒍𝒍:   1. 𝑸𝒖𝒊𝒄𝒌 𝑪𝒐𝒅𝒆 𝑻𝒆𝒔𝒕𝒊𝒏𝒈 JShell lets you test code snippets without creating an entire class or main method.   2. 𝑬𝒙𝒑𝒍𝒐𝒓𝒊𝒏𝒈 𝑨𝑷𝑰𝒔 You can test Java APIs in real-time to understand their behavior   3. 𝑾𝒓𝒊𝒕𝒊𝒏𝒈 𝑴𝒆𝒕𝒉𝒐𝒅𝒔 𝑰𝒏𝒍𝒊𝒏𝒆 Define methods directly in JShell to test functionality or modularize code.   4. 𝑳𝒐𝒐𝒑𝒊𝒏𝒈 𝒂𝒏𝒅 𝑪𝒐𝒏𝒅𝒊𝒕𝒊𝒐𝒏𝒂𝒍𝒔 Experiment with control structures like loops and conditionals without a full program.   5. 𝑫𝒆𝒇𝒊𝒏𝒊𝒏𝒈 𝒂𝒏𝒅 𝑴𝒐𝒅𝒊𝒇𝒚𝒊𝒏𝒈 𝑪𝒍𝒂𝒔𝒔𝒆𝒔 JShell supports creating classes and modifying them in real-time.   6. 𝑳𝒊𝒔𝒕𝒊𝒏𝒈 𝒂𝒏𝒅 𝑬𝒅𝒊𝒕𝒊𝒏𝒈 𝑪𝒐𝒅𝒆 𝑺𝒏𝒊𝒑𝒑𝒆𝒕𝒔 JShell commands like /list and /edit let you manage and modify snippets on the fly. JShell offers a powerful, interactive way to experiment with Java code, making it an invaluable tool for learning, debugging, and rapid prototyping.   With its instant feedback and ease of use, JShell empowers developers to explore Java's features without the overhead of a full development setup—perfect for those who want to test ideas on the fly and deepen their understanding of the language.

🚫 You’ll NEVER land a QA job interview, if you don't understand these secrets. I’ve interviewed over 1,000 QA professionals throughout the 15+ years of my career at Fortune 500 companies like Tinder and Barnes & Noble, as well as C-level executives at Engenious. Here’s what most were missing when struggling to land an interview. - Lack of clear job search strategy. - Resume not tailored to the job applied. - LinkedIn not Optimized for the correct keywords. - Lack of actionable tips to get noticed by the recruiters. - No personal branding. 🔑 LinkedIn is a gold mine for opportunities, only if you know how to navigate it correctly. 👉 Join me on 9th October, 9.00 AM PDT to learn the secrets to land your first QA job.
