Assigning variables with dynamic names in Java -

i'd assign set of variables in java follows:

int n1,n2,n3;  for(int i=1;i<4;i++) {     n<i> = 5; } 

how can achieve in java?

this not how things in java. there no dynamic variables in java. java variables have declared in source code (*). period.

depending on trying achieve, should use array, list or map; e.g.

int n[] = new int[3]; (int = 0; < 3; i++) {     n[i] = 5; }  list<integer> n = new arraylist<integer>(); (int = 1; < 4; i++) {     n.add(5); }  map<string, integer> n = new hashmap<string, integer>(); (int = 1; < 4; i++) {     n.put("n" + i, 5); } 

it possible use reflection dynamically refer to variables have been declared in source code. however, only works variables class members (i.e. static , instance fields). doesn't work local variables. see @fyr's "quick , dirty" example.

however doing kind of thing unnecessarily in java bad idea. inefficient, code more complicated, , since relying on runtime checking more fragile.

and not "variables dynamic names". better described dynamic access variables static names.

^{* - statement inaccurate. if use bcel or asm, can "declare" variables in bytecode file. don't it! way lies madness!}
