July 25, 2023 by Tarik

The other posts have given good advice, but I thought it might be nice to show an example of where it definitely makes a difference: using System; using System.Globalization; using System.Threading; class Test { static void Main() { CultureInfo turkish = CultureInfo.CreateSpecificCulture(“tr”); Thread.CurrentThread.CurrentCulture = turkish; // In Turkey, “i” does odd things string lower = … Read more

July 23, 2023 by Tarik

For your use case where the application runs on one server and the database runs on another, the choice between EJB and Spring is irrelevant.

What are the differences between LLVM bitcode and Java bytecode?

June 29, 2023 by Tarik

Assuming you mean JVM rather than Java: The LLVM is a low level register-based virtual machine. It is designed to abstract the underlying hardware and draw a clean line between a compiler back-end (machine code generation) and front-end (parsing, etc.). The JVM is a much higher level stack-based virtual machine. The JVM provides garbage collection, … Read more

Best way to compare two JSON files in Java

June 13, 2023 by Tarik

I recommend the zjsonpatch library, which presents the diff information in accordance with RFC 6902 (JSON Patch). You can use it with Jackson: JsonNode beforeNode = jacksonObjectMapper.readTree(beforeJsonString); JsonNode afterNode = jacksonObjectMapper.readTree(afterJsonString); JsonNode patch = JsonDiff.asJson(beforeNode, afterNode); String diffs = patch.toString(); This library is better than fge-json-patch (which was mentioned in another answer) because it can … Read more

In IE<9, .toStringing (function (x) {return x*x;}) gives “(function (x) {return x*x;})” While in chrome it gives: “function (x) {return x*x;}” If you compare: “function (x) {return x*x;}” > “1,2,3” // true “(function (x) {return x*x;})” > “1,2,3” // false Which is effectively the same as comparing: “f” > “1” “(” > “1” Which is … Read more

Bear in mind that I speak ASFAC++B. 🙂 I’ve put the most important differentiating factor first. Garbage Collection Garbage Collection (GC) is the single most important factor in differentiating between these languages. While C and C++ can be used with GC, it is a bolted-on afterthought and cannot be made to work as well (the … Read more
