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() methodimport 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() methodimport 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
