The application calls the getInstance() factory methods of the Cipher engine class, which in turn asks the JCA framework to find the first provider instance that supports "AES". The framework consults each installed provider, and obtains the provider's instance of the Provider class. (Recall ...
Before moving to example, let’s first create an algorithm to find first and last digit of a number. Algorithm Step 1: Take a number from the user. Step 2: Create two variables firstDigit and lastDigit and initialize them by 0. Step 3: Use modulo operator(%) to find last digit. Ste...
