The elements() method of java.security.Provider class is used to return an enumeration of the values in the given hashTable.
Syntax:
public Enumeration<Object> elements()
Return Value: This method returns an enumeration of the values in the hashtable.
Below are the examples to illustrate the elements() method:
Example 1:
Java
// Java program to demonstrate// elements() methodimport java.security.*;import java.util.*;public class GFG1 { public static void main(String[] argv) { try { // creating the object of SecureRandom SecureRandom sr = SecureRandom.getInstance("SHA1PRNG"); // getting the Provider of the SecureRandom sr // by using method getProvider() Provider provider = sr.getProvider(); // printing the Provider System.out.println("Provider of the SHA1PRNG: " + provider); // Declaring the variable of Enumeration<Object> type Enumeration<Object> enume; // getting the enumeration of the values enume = provider.elements(); // printing the enumerated value System.out.println("Enumeration of the values: \n"); while (enume.hasMoreElements()) { System.out.println("Value is: " + enume.nextElement()); } } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
