java - How to reduce copy-pasting? -

-

if have number of similar classes, say:

integer i0; integer i1; integer i2; integer i3; integer i4; integer i5; integer i6; integer i7; integer i8; integer i9;

and wanted avoid doing this:

i0 = 0; i1 = 1; i2 = 2; i3 = 3; i4 = 4; i5 = 5; i6 = 6; i7 = 7; i8 = 8; i9 = 9;

i'm thinking of doing similar achieve same result:

int cnt = 0; for(classname : arrayofclassnames {     classname = cnt++; }

how do that?

[clarification] appears misunderstood. thinking more along lines of having 10 separate classes still, not 1 array having 10 items.

use array or arraylist?

// using array integer[] ints = new integer[10]; (int = 0; < 10; i++) {     ints[i] = i; }  // using array list arraylist<integer> ints = new arraylist<integer>(); (int = 0; < 10; i++) {     ints.add(i); }

following on update, looking can achieved using 

class.forname(classname).newinstance();

however, suggest whatever save in time code it, lose in readability , ease of maintenance, may find false economy.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (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...

php - Replacing tags in braces, even nested tags, with regex -

-
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."
