i'm using couple of strings in code going reused within loop , i'm wondering best way initialize string variables improve memory usage: // sample purposes declare map, same thing // applies arraylist, database set, etc. point. map<string, string> samplemap = getmap(); int mapsize = samplemap.size(); // string initialization string a; string b = new string(); string c = ""; for(int = 0; < mapsize; i++){ = samplemap.get(i); b = somefunc(a); c = anotherfunc(a); // stuff strings } after loop, strings no longer used. you cannot optimize initialization or memory usage of strings in snippet of code, several reasons: java strings immutable - cannot change characters inside string, can point new string. in loop, called function (such afunc() or get() ) 1 responsible allocating string, not loop. for advanced programmers: if want optimize memory usage of strings, need use stringbuffer/stringbuilder or raw character array , pass...
