How to generate Argon2 in Java?

argon2.java

// Import library to generate Argon2
import de.mkammerer.argon2.Argon2;
import de.mkammerer.argon2.Argon2Factory;
import de.mkammerer.argon2.Argon2Factory.Argon2Types;

// Function to generaye Argon2
public static String generateArgon2(String inputString) throws Exception {
    int iterations = 2;
    int mem = 16;
    int parallelism = 2;
    int saltLen = 16;
    int hashLen = 16;
    Argon2Types type = Argon2Types.ARGON2d; // Argon2Types.ARGON2i and Argon2Types.ARGON2id

    Argon2 argon2 = Argon2Factory.create(type, saltLen, hashLen);
    char []byteInput = inputString.toCharArray();

    String strHex = argon2.hash(iterations, mem, parallelism, byteInput);
    return strHex;
}

// Function to verify Argon2
public static boolean verifyArgon2(String inputString, String hash) throws Exception {
    int saltLen = 16;
    int hashLen = 16;
    Argon2Types type = Argon2Types.ARGON2d; // Argon2Types.ARGON2i and Argon2Types.ARGON2id

    char []byteInput = inputString.toCharArray();
    Argon2 argon2 = Argon2Factory.create(type, saltLen, hashLen);
    boolean isValid = argon2.verify(hash, byteInput);

    return isValid;
}

// TEST
public static void main(String[] args) {
    try {
        // Generate Argon2
        String inputString = "nhsteck.com";
        String strHex = Hash.generateArgon2(inputString);
        System.out.println("Hex >> " + strHex);

        // Verify Argon2
        boolean isValid = Hash.verifyArgon2(inputString, strHex);
        System.out.println("Verify >> " + isValid);
    } catch (Exception ex) {
        ex.printStackTrace();
    }
}
