java - Should YamlConfiguration objects be closed? -


i've been working on plugin requires fair amount of data being stored. have being stored in custom config file found online works same default config.

the problem i'm having not sure how close file or if need to, know little yaml configurations. code template used below.

i'm curious advice on how should store larger amounts of data in future.

public class customconfig {     //store name of file load/edit     private final string filename;     //store plugin, file directory     private final javaplugin plugin;      //store actual hard disk file location     private file configfile;     //store ram file copy location     private fileconfiguration fileconfiguration;       //constructor taking plugin , filename     public customconfig(javaplugin plugin, string filename) {         //ensure plugin exists folder path         if (plugin == null)             throw new illegalargumentexception("plugin cannot null");         //set classes plugin variable 1 passed method         this.plugin = plugin;         //get name of file load/edit         this.filename = filename;         //get directory/folder of file load/edit         file datafolder = plugin.getdatafolder();         if (datafolder == null)             throw new illegalstateexception();         //load config file hard disk          this.configfile = new file(plugin.getdatafolder(), filename);          reloadconfig();     }      public void reloadconfig() {         //load memory file hard copy         fileconfiguration = yamlconfiguration.loadconfiguration(configfile);          // defaults in jar         file configfile = new file(plugin.getdatafolder(), filename);         if (configfile != null) {             yamlconfiguration defconfig = yamlconfiguration.loadconfiguration(configfile);             fileconfiguration.setdefaults(defconfig);         }     }      public fileconfiguration getconfig() {         if (fileconfiguration == null) {             this.reloadconfig();         }         return fileconfiguration;     }      public void saveconfig() {         if (fileconfiguration == null || configfile == null) {             return;         } else {             try {                 getconfig().save(configfile);             } catch (ioexception ex) {                 plugin.getlogger().log(level.severe, "could not save config " + configfile, ex);             }         }     }      public void savedefaultconfig() {         if (!configfile.exists()) {                         this.plugin.saveresource(filename, false);         }     } }

no. not have close yamlconfiguration objects.

while default config (javaplugin.getconfig()) bound lifecycle of plugin, custom ones disposed when other java object is, i.e. when garbage collector determines there no more references pointing them in code.
