Java Recipes vs BinaryHexCalc

A reference of everyday Java, from strings and collections to threading and design patterns. Every example comes with an explanation, and most of them run. • 22 sections: simple types, arrays and collections, classes, interfaces and generics, functions and lambdas, files, serialization, exceptions, regular expressions, threading, databases, patterns. • Run in the app: the example really executes and the output appears under the code. Needs an internet connection. • What changed in new versions: 8 sections from Java 9 to 21, with "before" and "after" code side by side. • Keyword and function reference: 160 articles, fully open with no daily counter. • SQL alongside: over 200 queries against a live practice database - JOIN, GROUP BY, subqueries, data types. • Edit examples and add your own - they stay in the app and are always at hand. • Search runs over the code itself, not just the titles: remember a fragment and you will find the example. • Everything except running works offline. No account needed. WHAT THE FREE VERSION INCLUDES 12 runs and 12 edits a day - the counter resets every morning. The keyword reference is open without limits. Up to 5 examples of your own. Copying in the free app is blocked after five attempts. The full version opens every example, removes the daily limits and raises running to 30 launches a day. One purchase, no subscription. Made by a developer for developers. In development since 2015.

Programmer Calc is a powerful calculator designed for developers, engineers, and computer science enthusiasts. Instantly convert between hexadecimal, decimal, and binary number systems, and perform advanced bitwise operations with ease. Key Features: - Multi-base support: HEX, DEC, BIN - Real-time conversion as you type - Interactive 64-bit Bit-Set panel for granular control - Bitwise operations: AND, OR, XOR, NOT, shifts, two’s complement - Mask & Copy: Highlight and copy masked values for any data type - Paste support: Long-press to paste values into any field - Equation history tracking - Square root and modulo operations - ntuitive UI with dark/light mode - Rate and feedback options The dashboard provides a single location to input and convert values among hexadecimal, decimal, and binary representations. Long-pressing any field pastes a number directly into the corresponding system for rapid entry. The Bit-Set panel offers granular control over every bit, updating all number formats immediately after each toggle. Multiplying values that exceed 64 bits returns 1, and square roots are rounded up to the nearest integer (for example, √15 becomes 4). The Mask & Copy feature highlights the bits for the selected data type and copies the masked value to the clipboard in one step, ensuring consistent data sharing. Whether you’re debugging, reverse engineering, or learning about binary math, Programmer Calc is your essential toolkit.
