Use of Native Classes to Speed Up Execution

• One can essentially augment supplied Java Runtime by supplying your own C or other code implementing a particular functionality in a higher performance mode

• This of course generates machine dependence and should only be used if really needed

• First for classes you wish to implement in native fashion, put in your java code lines like:

  • public native mustgofast(arguments); // default functions
  • static { System.loadLibrary("faststuffhere"); } // static and in class and so runs only ONCE! and loads the native code
