Get Property by Name

     

In this Tutorial we want to describe you a code that helps you in understanding to get Property by Name. For this we have a class name "Get Property By Name". Inside the main method  we have the list of method that help you to get the Properties of  System-

1)System.getProperties ( ) -  This Method returns you current system properties by assigning an instance of properties class and store the current system properties in it.

2)stringPropertyNames( ) -   This Method returns you the current system properties in a Set object  set (Collection interface).

3)Iterator ( )   -   This allow you to traverse the list of element in a collection.

We declare a String variable name key inside the main method followed by while loop, that  is used to evaluate or check more element present in a iterator .If more element is present, the iterator call next( ).to string returns you the next element in the iterator, convert it into a string and store in a String variable key. The System.out.println is used to print the properties of the system by calling properties.getProperty( key).

GetPropertyByName.java

import java.util.*;

public class GetPropertyByName {

  public static void main(String args[]) {

  Properties properties = System.getProperties();
  Set set = properties.stringPropertyNames();
  Iterator iterator = set.iterator();

  String key;
  while (iterator.hasNext()) {
  key = iterator.next().toString();

  System.out.print(key + " : ");
  System.out.println(properties.getProperty(key));
  }
  }
}
