getParent() method of a Logger class is used to get the parent of this Logger.This method returns the nearest extant parent in the namespace.if there is a Logger called “com.javac.core.api”, and a Logger called “com.javac” has been created but no logger “com.javac.core” exists, then a call of getParent on the Logger “com.javac.core.api” will return the Logger “com.javac”. The result will be null if we apply getParent() method on root Logger in the namespace.
Syntax:
public Logger getParent()
Parameters: This method accepts nothing.
Return value: This method return nearest existing parent Logger.
Below programs illustrate the getParent() method:
Program 1:
Java
// Java program to demonstrate// Logger.getParent() methodimport java.util.logging.*;public class GFG { public static void main(String[] args) { // Create a logger using getLogger() Logger logger = Logger.getLogger("com.java.core"); // Assign other package to logger logger = Logger .getLogger("com.java.core.api"); // Print parent name System.out.println("logger name = " + logger .getParent() .getName()); }} |
Output:
logger name = com.java.core
Program 2:
Java
// Java program to demonstrate// Logger.getParent() methodimport java.util.logging.*;public class GFG { public static void main(String[] args) { // Create a logger using getLogger() Logger logger = Logger.getLogger("com.java"); // Assign other package to logger logger = Logger.getLogger("com.java.core.api.base"); // Get Parent logger Logger parentLogger = logger.getParent(); // Print parent name System.out.println("Parent logger name = " + parentLogger.getName()); }} |
Output:
Parent logger name = com.java
