A Registration page (also known as a Sign-up page) . The source code is about How to Create a Registration Page using Java with Firebase Connectivity. This was developed using java
Through this program, I have to Create a Registration Page using Java with Firebase Connectivity. Through this registration page user easily fields the data. A registration form is a list of fields that a user will input data into or submit to an individual. This servlet class receives all the data entered by the user and stores an into the real-time database in firebase. here I have performed the real-time database logic but you may separate it.
