AlgorithmParameters getAlgorithm() method in Java with Examples

AlgorithmParameterGenerator getAlgorithm() method in Java with Examples

The getAlgorithm() method of java.security.AlgorithmParameters class is used to return the standard name of the algorithm this parameter generator is associated with.

Syntax:

public final String getAlgorithm()

Return Value: This method returns the string name of the algorithm.

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

Example 1: For Algorithm DSA

Java

// Java program to demonstrate
// getAlgorithm() method
 
import java.security.*;
import java.util.*;
 
public class GFG1 {
    public static void main(String[] argv)
    {
        try {
            // creating the object of
            // AlgorithmParameters
            // and getting instance
            // using getInstance() method
            AlgorithmParameters sr
                = AlgorithmParameters
                      .getInstance("DSA");
 
            // generating the Parameters
            // using getAlgorithm() method
            String algo = sr.getAlgorithm();
 
            // printing the string algo
            System.out.println("Algorithm: "
                               + algo);
        }
 
        catch (NoSuchAlgorithmException e) {
 
            System.out.println("Exception thrown: "
                               + e);
        }
        catch (ProviderException e) {
 
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

Output:

Algorithm: DSA

Example 2: For Algorithm DiffieHellman

Java

// Java program to demonstrate
// getAlgorithm() method
 
import java.security.*;
import java.util.*;
 
public class GFG1 {
    public static void main(String[] argv)
    {
        try {
            // creating the object of
            // AlgorithmParameters
            // and getting instance
            // using getInstance() method
            AlgorithmParameters sr
                = AlgorithmParameters
                      .getInstance("DiffieHellman");
 
            // generating the Parameters
            // using getAlgorithm() method
            String algo = sr.getAlgorithm();
 
            // printing the string algo
            System.out.println("Algorithm: "
                               + algo);
        }
 
        catch (NoSuchAlgorithmException e) {
 
            System.out.println("Exception thrown: "
                               + e);
        }
        catch (ProviderException e) {
 
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

Output:

Algorithm: DiffieHellman
