Interfaces for Custom Decryption in Java

Write a Java program to demonstrate the use of an interface for custom decryption

The Decryptor interface defines a single method decrypt(String data) for decrypting data.
In the main method of the Main class, an instance of the Decryptor interface is created using a lambda expression that performs Base64 decoding.
The encrypted data string is decrypted using the decrypt method of the Decryptor interface.
The encrypted and decrypted data are printed to the console.

Source Code

import java.util.Base64;
interface Decryptor
{
	String decrypt(String data);
}
 
public class Main
{
	public static void main(String[] args)
	{
		Decryptor decryptor = data -> new String(Base64.getDecoder().decode(data));
 
		String encryptedData = "SGVsbG8gV29ybGQhIDEyMw==";
		String decryptedData = decryptor.decrypt(encryptedData);
 
		System.out.println("Encrypted Data : " + encryptedData);
		System.out.println("Decrypted Data : " + decryptedData);
	}
}

Output

Encrypted Data : SGVsbG8gV29ybGQhIDEyMw==
Decrypted Data : Hello World! 123
