A POJO (Plain Old Java Object) is a regular Java object, not bound by any special restriction other than those forced by the Java Language Specification. Think of it like a normal class in Java that doesn't need to extend or implement some specialized classes or interfaces.
Adding or removing properties: It's like deciding to carry different items in your bag. For example, you might add a new property like 'email' to your POJO or remove an existing one like 'age'. Changing property types: This is like changing the kind of items you carry. For instance, changing a property from 'int' (numbers) to 'String' (text) in your POJO. Adding methods: Methods in a POJO are like tools that help you interact with the items in your bag. You can add new methods to do different things with your data, like calculating the age from a birthdate.
