Below programs illustrate getLoggerNames() method:
Program 1:
// Java program to illustrate// LogManager getLoggerNames() method import java.util.logging.*;import java.util.*; public class GFG { public static void main(String[] args) { // Create LogManager object LogManager logManager = LogManager.getLogManager(); Enumeration<String> listOfNames = logManager.getLoggerNames(); System.out.println("List of Logger Names: "); while (listOfNames.hasMoreElements()) System.out.println(listOfNames.nextElement()); }} |
Output:
List of Logger Names: global
Program 2:
// Java program to illustrate// LogManager getLoggerNames() method import java.util.logging.*;import java.util.*; public class GFG { public static void main(String[] args) { // Create LogManager object LogManager logManager = LogManager.getLogManager(); logManager.addLogger(Logger.getLogger("GFG")); Enumeration<String> listOfNames = logManager.getLoggerNames(); System.out.println("\nList of Logger Names: "); while (listOfNames.hasMoreElements()) System.out.println(listOfNames.nextElement()); }} |
