This article will explain in detail how to use preference settings and replace properties settings in JDK 1.4.The content of this article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

JDK 1.4 begins to provide preference settings that provide access to the registry under windows. But the user information is stored under the HKEY_CURRENT_USERSoftwareJavaSoftPrefs key and organized in a tree-like manner. Can be exported as a XML file. Do not know what to use under Linux to achieve registry functions, files? There was no experiment. [@ more@]

Package org.pitfalls.prefs

Import java.util.prefs.*

Public class PreferencesTest {

Private String mailServer

Private String timecardServer

Private String userName

Private String ftpServer

Public void storePreferences () {

Preferences prefs = Preferences.userRoot () .node (

"/ com/server")

Prefs.put ("mail", this.getMailServer ())

Prefs.put ("ftp", this.getFtpServer ())

}
