Java annotation

Java annotation is like putting sticky notes on your code. When you write your code, you can add annotations to it to give extra information to other parts of your program.

Think of it like you are drawing a picture and you want to make sure everyone knows which part is the sky and which part is the ground. You can put a sticky note on the sky part that says "SKY" and another one on the ground part that says "GROUND".

In Java, you can put annotations on things like methods, classes, and variables. These annotations can give extra information about what the code is doing or how it should be used. For example, you could put an annotation on a method that says it can only be accessed by certain users.

Annotations can be really helpful because they make it easier for other people to understand your code. If they see an annotation, they will know exactly what that part of the code is doing or what it's for.
