Last Updated :
06 Jun, 2021
The getAlgorithm() method of java.security.AlgorithmParameterGenerator 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
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
AlgorithmParameterGenerator
sr
= AlgorithmParameterGenerator
.getInstance( "DSA" );
sr.init( 1024 );
String algo = sr.getAlgorithm();
System.out.println( "Algorithm : " + algo);
}
catch (NoSuchAlgorithmException e) {
System.out.println( "Exception thrown : " + e);
}
catch (ProviderException e) {
System.out.println( "Exception thrown : " + e);
}
}
}

Example 2: For Algorithm DiffieHellman
Java
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
AlgorithmParameterGenerator
sr
= AlgorithmParameterGenerator
.getInstance( "DiffieHellman" );
sr.init( 1024 );
String algo = sr.getAlgorithm();
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
