Example
The following example shows the usage of java.util.ResourceBundle.handleGetObject() method.
package com.tutorialspoint; import java.util.Enumeration; import java.util.Locale; import java.util.ResourceBundle; import java.util.StringTokenizer; public class ResourceBundleDemo extends ResourceBundle { @Override public Object handleGetObject(String key) { if (key.equals("hello")) { return "Hello World!"; } else { return null; } } @Override public Enumeration getKeys() { StringTokenizer key = new StringTokenizer("Hello World!"); return key; } public static void main(String[] args) { // create a new ResourceBundle with specified locale ResourceBundle bundle = ResourceBundle.getBundle("hello", Locale.US); // print the string array assigned to key "hello" System.out.println("" + bundle.getString("hello")); } }
Assuming we have a resource file hello_en_US.properties available in your CLASSPATH, with the following content. This file will be used as an input for our example program −
hello = Hello World!
Let us compile and run the above program, this will produce the following result −
Hello World!
