Field, Method, Constructor, Superclass, Interface, Annotation
? All interfaces implemented
? The parent class inherited
Use reflection can be obtained:
1. All interfaces implemented
PUBLIC CLASS <?> GetInterfaces
Determine the interface or interface implemented by this object.
2. The parent class inherited
PUBLIC CLASS <? Super T> getsuperclass
Returns the Class of the parent class representing the entity (class, interface, basic type) represented by this Class.
3. All constructor
PUBLIC Constructor <T> getConstructors
Returns all public constructors of the classes represented by this Class object.
PUBLIC Constructor <T> getDeclaredConstructors
Returns all constructors of class declarations represented by this Class object.
? Get the modifier: public int getModifiers;
? Method name: public string getname;
Get the type of parameters: public class <?> GetparameterTypes;
4. All methods
Public Method getDeclaredMethods
Returns all methods for classes or interfaces represented by this Class object
PUBLIC METHOD GETMETHODS
Returns the method of publication of the class or interface represented by this Class object
PUBLIC CLASS <?> GetReturntype acquires all return values
PUBLIC CLASS <?> getParameterTypes acquires all of the parameters
Public Int getModifiers get modifies
PUBLIC CLASS <?> getExceptionTypes acquired exception information
5. All Field
Public Field getFields
? Returns the PUBLIC of the class or interface represented by this Class object.
Public Field getDeclaredfields
? Returns all Field of the classes or interfaces represented by this Class object.
? Field method:
Public IntModifiers Returns this Field modifier in an integer
PUBLIC CLASS <?> gettype gets the property type of the Field
PUBLIC STRING GETNAME Returns the name of the Field.
6. ANNOTATION related
? Get Annotation (Class <T> AnnotationClass)
7. Wild related
8. Category package package getpackage
1. In the actual operation, the operation code of the information obtained is not often developed.
2. Be sure to be familiar with the role of java.lang.Reflect package, reflection mechanism.
3. How to get attributes, methods, names, modifiers, etc. of the constructor.
