Provider getName() method in Java

Java 8 Programming Object Oriented Programming

The name of the provider can be obtained using the getName() method in the class java.security.Provider. This method requires no parameter and it returns the name of the provider as required.

A program that demonstrates this is given as follows −

Example

Live Demo

import java.security.*;
import java.util.*;
public class Demo {
   public static void main(String[] argv) {
      try {
         KeyPairGenerator kpGenerator = KeyPairGenerator.getInstance("DSA");
         Provider p = kpGenerator.getProvider();
         System.out.println("The Provider is: " + p.getName());
      } catch (NoSuchAlgorithmException e) {
         System.out.println("Error!!! NoSuchAlgorithmException");
      }
   }
}

Output

The Provider is: SUN

Now let us understand the above program.

The getProvider() method is used to get the provider of the key pair object. Then the provider is displayed. If the algorithm name is wrong, then the exception NoSuchAlgorithmException is thrown. A code snippet that demonstrates is given as follows −

try {
   KeyPairGenerator kpGenerator = KeyPairGenerator.getInstance("DSA");
   Provider p = kpGenerator.getProvider();
   System.out.println("The Provider is: " + p.getName());
} catch (NoSuchAlgorithmException e) {
   System.out.println("Error!!! NoSuchAlgorithmException");
}
