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
