Improve the performance of your Java code Hits: 28 ***** 4.0 Many algorithms are expressed       most concisely as       tail-recursive methods.       Compilers can automatically       transform such methods into       loops and thereby improve       program performance, but       this transformation is not       required by the Java       language specification,       so not all JVMs will perform       it. This means that       tail-recursive methods in       the Java language can result       in unexpectedly large memory       usage. This article       demonstrates that dynamic       compilation maintains the       language's semantics while       static compilation often       doesn't. Learn why this       matters and get a bit of       code to help you determine       whether your just-in-time       (JIT) compiler can transform       tail recursion on code while       preserving semantics.       Date: Jun, 02 2001
