The following example shows the usage of java.util.PropertyResourceBundle.getKeys() method.
package com.tutorialspoint; import java.io.IOException; import java.io.InputStream; import java.io.StringBufferInputStream; import java.util.Enumeration; import java.util.PropertyResourceBundle; public class PropertyResourceBundleDemo { public static void main(String[] args) { // Prepare content for simulating property files String fileContent = "# Integer value 1\n" + "s1 = 1\n" + "# String value PropertyResourceBundleDemo\n" + "s2 = PropertyResourceBundleDemo\n" + "# Date value Fri Jan 31 00:00:00 IST 3913\n" + "s3 = Fri Jan 31 00:00:00 IST 3913"; InputStream propStream = new StringBufferInputStream(fileContent); try { // Create property resource bundle PropertyResourceBundle bundle = new PropertyResourceBundle(propStream); // Get resource keys Enumeration<String> keys = bundle.getKeys(); while(keys.hasMoreElements()) { System.out.println("Bundle key: "+keys.nextElement()); } } catch (IOException e) { e.printStackTrace(); } } }
Let us compile and run the above program, this will produce the following result −
Bundle key: s2 Bundle key: s1 Bundle key: s3
