Provider getVersion() method in Java with Examples

Last Updated : 12 Jun, 2019
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 
// 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 
// 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
