executable jar - Java Desktop Application - memory -


i'm creating java desktop application(runnable jar file). i'm getting path user when running first time (like workspace in eclipse).

i want application remember path when i'm closing application , running again (like eclipse remembering workspace).

but cant because everytime when close application , running again variables reinitialized.

eclipse desktop application. how eclipse doing , how can implement in application.

as suggested berger can use preferences api as:

public static void main(string[] args) {     try (scanner in = new scanner(system.in)) {         preferences userroot = preferences.userroot();         string workspace = userroot.get("workspace", null);         if (null != workspace) {             system.out.println(workspace);             system.out.println("would change value (y/n):");             string option = in.nextline();             if ("y".equals(option) || "y".equals(option)) {                 updateworkspace(in, userroot);             }         } else {             updateworkspace(in, userroot);         }     } catch (exception e) {         e.printstacktrace();     } }  private static void updateworkspace(scanner in, preferences userroot) {     string workspace;     system.out.println("enter value workspace:");     workspace = in.nextline();     userroot.put("workspace", workspace); }

this sample example. based on need can make changes accordingly.

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
