Using Resource Bundle in Java

How to read resource bundle in java?

BundleTest.java

package org.metadata.core.xml; import java.text.MessageFormat; import java.util.MissingResourceException; import java.util.ResourceBundle; public class BundleTest {       private ResourceBundle bundle;       public BundleTest() {             bundle = ResourceBundle.getBundle("messages");       }       public String getMessage(String id, Object... params) {             String text = null;             try {                   text = bundle.getString(id);             } catch (MissingResourceException e) {                   text = "!! key " + id + " not found !!";             }             if (params != null) {                   MessageFormat mf = new MessageFormat(text);                   text = mf.format(params, new StringBuffer(), null).toString();             }             return text;       }       public static void main(String[] args) {             BundleTest test = new BundleTest();             String message_1 = test.getMessage("MESSAGE_ONE");             System.out.println(message_1);             String message_2 = test.getMessage("MESSAGE_TWO", "ZTO", "Myanmar");             System.out.println(message_2);       } }

1. Create a folder name with “resources” and set the folder into the classpath. 
2. Put the “messages.properties” file into the “resources” folder.

messages.properties

MESSAGE_ONE = Hello World! MESSAGE_TWO = Hi {0}! Welcome from {1}!

Output

Hello World! Hi ZTO! Welcome from Myanmar!
