Provider getName() method in Java with Examples

The getName() method of java.security.Provider class is used to return the name of this provider. 

Syntax:

public String getName()

Return Value: This method returns the name of this provider.

Below are the examples to illustrate the getName() method: 

Example 1:

Java

// Java program to demonstrate
// getName() 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 name of the provider using getName()
            String name = provider.getName();

            // printing the string info
            System.out.println("name : " + name);
        }

        catch (NoSuchAlgorithmException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output:

name : SUN

Example 2:

Java

// Java program to demonstrate
// getName() 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 name of the provider using getName()
            String name = provider.getName();

            // printing the string info
            System.out.println("name : " + name);
        }

        catch (NoSuchAlgorithmException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output:

name : SUN
