Annotations associate meta-information with definitions.
Java
/**
* annotation definition
*/
public @interface myAnnotation {
int id();
String string1();
String string2() default "[unassigned]";
String string3(); default "[unimplemented]";
}
using annotation we specify name-value pairs:
@myAnnotation(
id = 44464,
string1 = "abc",
string2 = "def",
string3 = "hfg"
)
public static void myClass(int value) { ... }
