Overview

The getProvider() method is used to get the provider for the SecureRandom object. The provider contains encryption algorithms. This method is provided by the SecureRandom class, which consists of methods to generate strong random numbers.

We can get the provider of the current instance of the SecureRandom object using the getProvider() method.

Syntax

public final Provider getProvider()

Parameters

This method doesn't take any parameters.

Return value

This method returns the provider of the SecureRandom object on which it is called.

Example

import java.security.*;
import java.util.*;

public class main {
	public static void main(String[] argv)
	{
		//create instance of securerandom
		SecureRandom rndm = new SecureRandom();

    	//get provider of secure random object
		System.out.println(rndm.getProvider());
	}
}

Explanation

  • Line 8: We create an instance of the SecureRandom class and assign it to the variable, rndm.
  • Line 11: We get the provider of the SecureRandom object, rndm, using the getProvider() method and display it.
