The getVersion() method of java.security.Provider class is used to return the version number for this provider
Syntax:
public double getVersion()
Return Value: This method returns the version number for this provider.
Below are the examples to illustrate the getVersion() method:
Example 1:
// Java program to demonstrate// getVersion() method import java.security.*;import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { 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(); // getting the version of the provider using getVersion() method double version = provider.getVersion(); // printing the string info System.out.println("version : " + version); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
version : 1.8
Example 2:
// Java program to demonstrate// getVersion() method import java.security.*;import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { try { // creating the object of KeyPairGenerator KeyPairGenerator sr = KeyPairGenerator.getInstance("DSA", "SUN"); // getting the Provider of the KeyPairGenerator sr // by using method getProvider() Provider provider = sr.getProvider(); // getting the version of the provider using getVersion() method double version = provider.getVersion(); // printing the string info System.out.println("version : " + version); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
version : 1.8
