Note Taking

This document contains code for two Java programs: 1) A Person class with private name and age fields and getter/setter methods to work with a Person object. The main method gets user input and demonstrates using the Person object. 2) A GUI program with buttons to insert and delete a name from a database table. It connects to a MySQL database and executes INSERT and DELETE SQL statements on button clicks.
