Following a suggestion by extempore recently about how to get scala to tell me whether there was boxing going on by looking at the bytecode, I created this class:
We are using axis2 to generate web-service clients, (I regret this now!). With axis2 command-line tool you can pass switch -Euwc to wrap int into Integer, boolean into Boolean and so on in generated s
I\'ve searched for the use of @specialized in the source code of the standard library of Scala 2.8.1. It looks like only a handful of traits and classes use this annotation: Function0, Function1, Func
I would like to use code similar to the following: int letterIndex[]; LinkedList<Integer> letterList;
I am trying to figure this out: double chiSquare = ((double)(hashtable.get(key).intValue()/noWords))/* * Math.log10((NO_DOCUMENTS/all.get(key)))*/;
Java has both object, Integer, and primitive version, int, of basic types. The primitive versions are faster/lighter/etc. so in general you should use them.
From the answer to a ques开发者_如何学Gotion about primitive types and autoboxing in java: for biziclop:
Since Java 5, we\'ve had boxing/unboxing of primitive types so that int is wra开发者_运维知识库pped to be java.lang.Integer, and so and and so forth.
I really can\'get my head around why the following happens: Double d = 0.开发者_C百科0; System.out.println(d == 0); // is true
I\'m attempting to use both Perl\'s autoboxing functionality and operator overloading functionality, and they don\'t seem to be working in tandem.
