Example
The following example shows the usage of java.util.Properties.loadFromXML() method.
package com.tutorialspoint; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.util.*; public class PropertiesDemo { public static void main(String[] args) { Properties prop = new Properties(); // add some properties prop.put("Height", "200"); prop.put("Width", "15"); try { // create a output and input as a xml file FileOutputStream fos = new FileOutputStream("properties.xml"); FileInputStream fis = new FileInputStream("properties.xml"); // store the properties in the specific xml prop.storeToXML(fos, null); // load from the xml that we saved earlier prop.loadFromXML(fis); // print the properties list prop.list(System.out); } catch (IOException ex) { ex.printStackTrace(); } } }
Let us compile and run the above program, this will produce the following result −
-- listing properties -- Width=15 Height=200
