currently writing application in java looks through files in directory (call 'topics'). within directory number of folders named after respective topics, maybe 'dog', 'cat', etc. i using scheduledexecutorservice through directory every 30 seconds, going through each topic folder , performing operation on contents in folder (we'll other independent piece of code writing these topic folders, maybe log file or something). what best way examine new subdirectories each 30 seconds? if start topic dog, , somewhere between 30 seconds topics 'cat' , 'bird' added, best way me through new folders? thinking comparing hashset or something, i'm not sure efficient way this. i ask because there potentially great amount of subdirectories being created, , seems me problematic try loop through each 1 directory.listfiles(). advice? use java's watchservice api. the watchservice api low level, allowing customize it. can use is, or c

i have table " t_person " 2 fields search by: height int, birthdate datetime . when query table want rows values near searched. example when search people height of 175 cm, this: select * t_person height = 175 i rows height value near 175. eg 174, 173,176... same thing date column. when search '2003-06-25', dates close it. is possible? you need sort of measure on constitutes close. suspect want exact matches appear first. so, order rows "nearness" use: select p.* t_person p order abs(height - 175); filtering results useful, can add where clause: select p.* t_person p height between 175 - 2 , 175 + 2 order abs(height - 175); the same idea can work dates. however, don't specify database in question , date functions highly database specific.

i'm using apache's commons-configuration (v 1.10) library provide configuration values program. use compositeconfiguration of systemconfiguration , propertiesconfiguration in order allow users override properties file java's -d command-line argument. the problem i'm running validation of values in configuration (ensure value of x positive, example). near can tell, commons-configuration library (neither 1.10 nor 2.0-beta) not provide means of validating configuration values. yes, can validate xml document that's used xmlconfiguration (and that's hear if try google answer question). doesn't me values come systemconfiguration part of configuration class. so, missing something? library provide way validate values i'm missing, or there java library that's built on commons-configuration provides validation capabilities? or need build derivative of compositeconfiguration ?

i found out can use regex search queries in find , replace in visual studio. have lot of similar lines so: datum["id"] = id; datum["name"] = name; i have more lines so: this.id = datum["id"]; this.name = datum["name"]; i want turn first lines to: datum.set("id", id); datum.set("name", name); and second set of lines to: this.id = datum.get<int>("id"); this.name = datum.get<int>("name"); how possible find , replace , regex? can't figure out. after enabling regular expression clicking on 'use regular expression' button, place following in find: datum\[\"id\"\]\s*=\s*id\; and place following in replace (no need use regex in replace): datum.set("id", id); similarly: in find: datum\[\"name\"\]\s*=\s*name\; in replace: datum.set("name", name); in find: this\.id\s*=\s*datum\[\"id\"\]\;

an object can copied between survivor spaces 7 times before relocated old generation space , understand object has every chance of being garbage collected before being put old generation space. lecture listening states avoid object promotion young generation space old generation space. my question why promotion old generation bad? lecture doesn't explain that. why old generation bad? the lecture listening states avoid object promotion young generation space old generation space. it's not promotion old generation bad in general . it's bad when objects short lifetime promoted accident. you want long-lived objects in old generation not interfere minor collections. allocation rates inverse object lifetimes (which gives rise weak generational hypothesis) . in means short-lived objects generated @ high rate. , in turn means: if short-lived objects promoted old gen old gen filled @ high rate. minor gcs less expensive major gcs, in terms of pause t

my question simple: should create debug class singleton? i know the singleton pattern bad practice , debug class not take part in logic in app, , complexify entire application inject debug class every class. my debug class contain methods such as: debug::message(); debug::dump(); debug::spot(); // create timeline // etc it should noted use the debugbar package , , present in dev mode, debug class if package present, if so, pass informations it, otherwise, nothing (or maybe log important things). ok, want do static calls avoid tossing around instance of debug class. makes sense. and if want use static calls, alternative singleton write class consists of static properties/methods. the decision whether go or singleton pretty simple: class have internal state and/or require constructor? example, if open log file or instantiate other objects, you’ll want singleton. singleton frowned upon, , there are reasons this . there still situations makes sense , valid appro
