mysql - What to store an IP as in Java -


i connecting java program mysql database, need ip connect it. hard coding ip bad idea made config. problem not sure store ip in variable. looked around lot of places int, don't see how can correct because integers don't have decimals. should do?

edit: answer mattias f more appropriate situation. being said, i'll explain why you've heard ip address can stored in integer.

an ipv4 address consists of 4 octects, or 4 bytes of data. incidentally, that's how information 32-bit integer can hold. here methods go both ways:

public static int ipstringtointeger (final string ip) {     int value = 0;     final string[] parts = ip.split ("\\.");     (final string part : parts)         value = (value << 8) + integer.parseint (part);     return value; } public static string ipintegertostring (int ip) {     final string[] parts2 = new string[4];     (int = 0; < 4; i++)     {         system.out.println ("value : " + (ip & 0xff));         parts2[3 - i] = integer.tostring (ip & 0xff);         ip >>= 8;     }     return parts2[0] + '.' + parts2[1] + '.' + parts2[2] + '.' + parts2[3]; }

edit: integer.valueof replace integer.parseint, unihedron

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
