  1. An introduction to the Java Native Interface

    The Java Native Interface is a way for users to run native code (i.e. code not JIT-ed/interpreted by a JVM). These are typically written in C/C++ (I'm not positive if this is a requirement, but they're definitely the most common languages used with JNI).

    In this post, I will give a brief introduction to using JNI, when to use JNI, and some mistakes that could happen when using JNI. For the purposes of this simple tip, a focus is given on Java invoking native code, however the JNI ...

  3. How and why an SSCCE?

    The term SSCCE gets thrown around a lot in online programming forums. Its a simple acronym that stands for Short, Self Contained, Correct Example. But what is so important about an SSCCE? For starters, creating an SSCCE provides a very simple example that clearly demonstrates a given problem, helping one receive help and advice much quicker. But it also goes far beyond just that. Often just the process alone of writing an SSCCE will unveil the problem at hand. But even more important, the process ...
  4. Debugging with System.out.println

    System.out.prinln is quite possibly the most useful debugging tool there is - especially for the beginner programmer with no knowledge of other tools such as debuggers, assertions, and/or loggers. System.out.println prints to the command line the values passed to the method as an argument (if an object is passed, the String returned by Object.toString() is printed).
