My Java Tips

There are three categories of annotations namely Marker, Single-Value and Full annotation.

---

Let me present these one by one:

Marker annotations

There annotations have no variables. These are identified by name, with no additional data supplied. For example:
Code:


@SingleValueAnnotation

Single-value annotations

These are similar to markers, but also provide a single piece of data. You can only provide a single bit of data with these. For example:
Code:

Java Code:

@SingleValueAnnotation("my data")

Full annotations

There have multiple data members. Annotations of this type won’t look quite so much like a normal Java method:

Java Code:

@FullAnnotation(var1="data value 1", var2="data value 2", var3="data value 3")
