Why is there no Constant feature in Java? -

-

i trying identify reason behind constants in java have learned java allows declare constants using final keyword.

my question why didn't java introduce constant (const) feature. since many people has come c++, in c++ have const keyword.

please share thoughts.

every time go heavy c++ coding java, takes me little while adapt lack of const-correctness in java. usage of const in c++ different declaring constant variables, if didn't know. essentially, ensures object immutable when accessed through special kind of pointer called const-pointer when in java, in places i'd want return const-pointer, instead return reference interface type containing methods shouldn't have side effects. unfortunately, isn't enforced langauge.

wikipedia offers following information on subject:

interestingly, java language specification regards const reserved keyword — i.e., 1 cannot used variable identifier — assigns no semantics it. thought reservation of keyword occurred allow extension of java language include c++-style const methods , pointer const type. enhancement request ticket in java community process implementing const correctness in java closed in 2005, implying const correctness never find way official java specification.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
