Annotation Type NotNull

@Target(value={FIELD,PARAMETER,METHOD})
 @Retention(value=RUNTIME)
public @interface NotNull

A program element annotated @NotNull should always have a value.

• Field: Should be initialized within the class constructors or initializers and not become a null pointer during runtime.
• Method: Should never return null
• Parameter: Should not be null, otherwise most probable a NullPointerException is thrown.
