Inner class reflection
Hello !
I have the following class (excerpt):
public final class Patient
public Patient()
//...some code here
public PatientFilter Filter = new PatientFilter();
public final class PatientFilter
public String Pkey = "";
public String Snm = "";
public String Fnm1 = "";
public String Fnm2 = "";
public void clear()
Pkey = "";
Snm = "";
Fnm1 = "";
Fnm2 = "";
In another .java file I have the following code:
private void init()
Patient patient = new Patient();
ProcessObject(patient);
private String ProcessObject(Object obj)
//here I want to call via reflection: patient.Filter.clear();
So basically I have several "Patient like" classes and I want to call myPatientLikeObject.Filter.clear() from within ProcessObject() function.
How can I do that?
Many Thanks,
Vasile
OK, these are the java sources :
Patient.java
public final class Patient
public Patient()
//...some code here
public PatientFilter Filter = new PatientFilter();
public final class PatientFilter
public String Pkey = "";
public String Snm = "";
public String Fnm1 = "";
public String Fnm2 = "";
public void clear()
Pkey = "";
Snm = "";
Fnm1 = "";
Fnm2 = "";

Using Reflection can we find out details of inner classes in a class
Hello All,
Thanx in advance.
I intend to figure out the name of the inner class and methods declared inside it. How can this be done using reflection API's.
I need the above information to make an automated java doc creation tool for the project I am working in.
Thanx again...
VIkasThanx silkm,
Actually suggestion # 1 I have already tried. I used
getClasses() method which returned me a Class[] of
length = 0. i dunno Why?Because you are not using the reflection API correctly. If you read the javadocs you would know that it is structured so that all getXXX() methods return all XXX things that are public and are either declared by the target class or possibly inherited from superclasses.
As contrasted to that, getDeclaredXXX() methods can return all XXX things (including private) but only declared by the target class (not inherited).
You got an empty result back in your case most likely because all your nested/inner classes were non-public. Use getDeclaredClasses() instead.
As to suggestion # 2, the exercise I am doing is a
step before using the java doc tool. One has to insert
a javadoc comment before the method begins in order to
create a java doc. So thats it.This is independent of the reflection API but you might consider using the doclet API for this. -
How to access private method of an inner class using reflection.
Can somebody tell me that how can i access private method of an inner class using reflection.
There is a scenario like
class A
class B
private fun() {
now i want to use method fun() of an inner class inside third class i.e "class c".
Can i use reflection in someway to access this private method fun() in class c.I suppose for unit tests, there could be cases when you need to access private methods that you don't want your real code to access.
Reflection with inner classes can be tricky. I tried getting the constructor, but it kept failing until I saw that even though the default constructor is a no-arg, for inner classes that aren't static, apparently the constructor for the inner class itself takes an instance of the outer class as a param.
So here's what it looks like:
//list of inner classes, if any
Class[] classlist = A.class.getDeclaredClasses();
A outer = new A();
try {
for (int i =0; i < classlist.length; i++){
if (! classlist.getSimpleName().equals("B")){
//skip other classes
continue;
//this is what I mention above.
Constructor constr = classlist[i].getDeclaredConstructor(A.class);
constr.setAccessible(true);
Object inner = constr.newInstance(outer);
Method meth = classlist[i].getDeclaredMethod("testMethod");
meth.setAccessible(true);
//the actual method call
meth.invoke(inner);
} catch (Exception e) {
throw new RuntimeException(e);
Good luck, and if you find yourself relying on this too much, it might mean a code redesign. -
Instantiation an inner class using reflection
I want to instantiate an inner class using the Class.newInstance() method called within the Outer class constructor:
public Outer
public Outer()
Inner.class.newInstance();
private Class Inner { }
When I try it, however, I get an InstantiationException.
Is there some way to do this?
Thanks for the help.
ScottHere is a consolidation of what everyone posted and it does appear to work. In one of your post you used the getDeclaredConstructors() method and said it was less than ideal; I am not sure what you meant but I suspect it was the hard coded array reference. Anyhow I used the getDeclaredConstructor() method which appears to get non-public constructors also and is basically the same as using the getConstructor() method.
import java.lang.reflect.*;
public class Test35 {
static public void main(String[] args) {
Test35 t35 = new Test35();
t35.testIt();
private class Inner {
public String toString() {
return "Hear I am";
public void testIt() {
try {
Constructor con = Inner.class.getDeclaredConstructor(new Class[] {Test35.class});
Inner in = (Inner)con.newInstance(new Object[] {this});
System.out.println(in);
} catch (Exception e) {
e.printStackTrace(); -
Passing Inner class name as parameter
Hi,
How i can pass inner class name as parameter which is used to create object of inner class in the receiving method (class.formane(className))
Hope somebody can help me.
Thanks in advance.
PremNo, because an inner class can never have a constructor that doesn't take any arguments.
Without going through reflection, you always need an instance of the outer class to instantiate the inner class. Internally this instance is passed as a parameter to the inner class's constructor. So to create an instance of an inner class through reflection you need to get the appropriate constructor and call its newInstance method. Here's a complete example:import java.lang.reflect.Constructor;
class Outer {
class Inner {
public static void main(String[] args) throws Exception{
Class c = Class.forName("Outer$Inner");
Constructor cnstrctr = c.getDeclaredConstructor(new Class[] {Outer.class});
Outer o = new Outer();
Inner i = (Inner) cnstrctr.newInstance(new Object[]{o});
System.out.println(i);

Inner Classes Changing Access Rights Of Parent Members
I read that if you access a parent class's private memebers or methods from within an inner class, those members of methods will automatically and silently be converted to having package access. This seems dangerous and I'd like to know how I could design around it.
Here is my current dilemma. I have an EventHandler class whose handleEvent() method changes with the object's state. I've implemented this using the Strategy Pattern, where the Strategy objects are inner classes of EventHandler. The problem is that these Strategy objects need access to certain private members and methods of their parent. There is no reason, however, to give package access to these members and methods. What can I do? Or does this suggest that I need a design change? Other than this issue, though, I'm quite happy with the design.
Thanks for any thoughts,
JohnWhen inner classes access private fields or methods, the compiler generates new package-private methods
with names like "access$000":
import java.lang.reflect.*;
public class X {
private void x() {}
class Y {
public void y() {
x();
public static void main(String[] args) {
Method[] methods = X.class.getDeclaredMethods();
for(int i=0; i<methods.length; ++i)
System.out.println(methods.getName());
So it's not correct that the access to fields or methods is changed, just that additional methods are added.
Unless you're in the habit of writing method names that contain '$', I think it's unlikely that you'll directly call
these new methods, and if you do, it should be easy to spot! -
Dear Friends
Can any one help me to find a solution for the following problem:
I am using a class with inner class and table model. I wanted to get the list of all attributes from both inner and outer classes. All attributes are declared public. I used the Class / Reflection and managed to get the list of attribute in the inner class as shown below. The following code neatly listed all the attributes in the inner class but not the one in outer class.
Class c = classA.innerClassA_.getClass() ;
Try
Field[] fa = c.getFields() ;
For(int i=0; i<fa.length; i++)
Field f = fa;
System.out.println(f) ;
catch(SecurityException se)
Thanks in anticipation,
sunderYou'll need to start with listing all inner classes by using the method:
getDeclaredClasses() in java.lang.Class.
In your case:
classA.class.getDeclaredClasses();Where I presume assume that classA is the class that holds the internal classes.
This will give you an array of all your internal classes.
Given this you can simply find all declared fields in you inner classes.
Hope this was to some help -
Inaccessible with local variable(non-final) via method local inner class
Hi All,
Usually local variables, including automatic final variable live on the stack and objects & instanace variables live on the heap.The contracts for using the method local inner class should allow merely method final variable, not non-final stack variable.
Can anyone please clarify me ,behind the scene what is actual fact why method inner class should not access the stack(method) variable and only allow final variable?
Is anything correlated with the stack and heap aspects?
Thanks,

...Final variables are copied into inner classes - that's why they have to be declared final; to avoid the developer making an incorrect assumption that the local variable can be modified and have the change reflected in the copy.
When a local class uses a local variable, it doesn't actually use the variable. Instead, it takes a copy of the value which is contained in the variable at the moment the class is instantiated. It's like passing the variable to a constructor of the class, except that you do not actually declare any such constructor in your code.
To avoid messy execution flows to be present in a Java method, the Java language authors thought it was better to allow a single value to be present in such a variable throughout all its life. Thus, the variable has to be declared final.

Hi everybody,
I can't seem to find a clear answer on this, and it's probably a silly simple question, but here goes (it needs a little setup first)--
A base class X has two subclasses, Y and Z.
Both Y and Z have static inner classes which contain a factory method that calls their constructors (that is, the methods call the constructors for class Y or class Z).
Is it possible to have an inner class Q in base class X which can be inherited by classes Y and Z and used to call the constructors of Y and Z?
Making a separate inner class for each subclass works fine, but they are very similar from class to class, and it would be nice to be able to do this to cut down on code.
If this is possible, I have one more question:
Is it possible to have an inner class R in class Y that extends inner class Q in class X?
If anyone could give me some clarification on these questions, and, if possible, the syntax to answer them, I'd appreciate it.
Thanks,

By the way, did you see my reflection example in your other thread?

Problem with Outer and Inner Classes....or better way?
Right now I'm trying to create an Inner class.
My .java file compiles ok, and I create my jar file too.
But when I try to instantiate the Inner class, it fails:
java.lang.NoClassDefFoundError: com/myco/vlXML/vlXML$vlDocument.
Here's the class code:
public class vlXML{
private ArrayList myDocList=new ArrayList(); //holds documents
public vlXML(){
private class vlDocument{
public vlDocument(){
//stuff goes here
public vlDocument vlDOC(){
return new vlDocument();
public void addDocument(){
vlXML xxx=new vlXML();
vlDocument myDoc=xxx.vlDOC();
myDocList.add(myDoc);
public int getNumDocs(){
return myDocList.size();
}Then, from a jsp page, I call:
vlXML junk1=new vlXML();
junk1.addDocument();...and get the error...
Can someone help me figure out why it's failing?
Thanks....You nailed it - thanks....(duh!)
While I have your attention, if you don't mind, I have another question.
I'm creating a Class (outer) that allows my users to write a specific XML file (according to my own schema).
Within the XML file, they can have multiple instances of certain tags, like "Document". "Document"s can have multiple fields.
Since I don't know how many "Documents" they may want, I was planning on using an Inner Class of "Document", and then simply letting them "add" as many as necessary (thus the original code posted here).
Does that seem like an efficient (logical/reasonable) methodology,
or is there there something better?
Thanks Again... -
Problem with final variables and inner classes

Problem with final variables and inner classes (JDK1.1.8)
When using JDK1.1.8, I came up with following:
public class Outer
protected final int i;
protected Inner inner = null;
public Outer(int value)
i = value;
inner = new Inner();
inner.foo();
protected class Inner
public void foo()
System.out.println(i);
}causing this:
Outer.java:6: Blank final variable 'i' may not have been initialized. It must be assigned a value in an initializer, or in every constructor.
public Outer(int value)
^
1 error
With JDK 1.3 this works just fine, as it does with 1.1.8 if
1) I don't use inner class, or
2) I assign the value in initializer, or
3) I leave the keyword final away.
and none of these is actually an option for me, neither using a newer JDK, if only there is another way to solve this.
Reasons why I am trying to do this:
1) I can't use a newer JDK
2) I want to be able to assign the variables value in constructor
3) I want to prevent anyone (including myself ;)) from changing the value in other parts of the class (yes, the code above is just to give you the idea, not the whole code)
4) I must be able to use inner classes
So, does anyone have a suggestion how to solve this problem of mine? Or can someone say that this is a JDK 1.1.8 feature, and that I just have to live with it? In that case, sticking to solution 3 is probably the best alternative here, at least for me (and hope that no-one will change the variables value). Or is it crappy planning..?You cannot use a final field if you do not
initialize it at the time of declaration. So yes,
your design is invalid.Sorry if I am being a bit too stubborn or something. :) I am just honestly a bit puzzled, since... If I cannot use a final field in an aforementioned situation, why does following work? (JDK 1.3.1 on Linux)
public class Outer {
protected final String str;
public Outer(String paramStr) {
str = paramStr;
Inner in = new Inner();
in.foo();
public void foo() {
System.out.println("Outer.foo(): " + str);
public static void main( String args[] ) {
String param = new String("This is test.");
Outer outer = new Outer(param);
outer.foo();
protected class Inner {
public void foo() {
System.out.println("Inner.foo(): " + str);
} producing the following:
[1:39] % javac Outer.java
[1:39] % java Outer
Inner.foo(): This is test.
Outer.foo(): This is test.
Is this then an "undocumented feature", working even though it shouldn't work?
However, I assume you could
get by with eliminating the final field and simply
passing the value directly to the Inner class's
constructor. if not, you'll have to rethink larger
aspects of your design.I guess this is the way it must be done.

Problem with constructor of inner class.
Hi everybody!
I have an applet which loads images from a database.
i want to draw the images in a textarea, so i wrote an inner class, which extends textarea and overrides the paint method.
but everytime i try to disply the applet in the browser this happens:
java.lang.NoClassDefFoundError: WohnungSuchenApplet$Malfl�che
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Class.java:1590)

at sun.applet.AppletPanel.runLoader(AppletPanel.java:496)
at sun.applet.AppletPanel.run(AppletPanel.java:293)
at java.lang.Thread.run(Thread.java:536)
so my class has no own constructor, it just has the paint method overwritten.
my class looks like this:
public class Malfl�che extends javax.swing.JTextArea{
public void paint(Graphics g){
Color grey=new Color(220,220,220);
g.drawImage(img,10,10,null);
how should a constructor for this class look like?
sorry i am quite new to this, so i really dont have a clue!
my class does not have any attributes or requires any so it doesnt need a constructor, doesnt it?
thanks a lot
timFirst off, unlike regular classes, inner classes can be declared public, private, protected, and default.
Secondly, why are you using the JTextArea to display an image, why not use a JLabel, which takes an Image object as its constructor.
Thirdly, when you drew your image you did not give it a width and height
g.drawImage(img, 0,0, img.getWidth(null), img.getHeight(null), null);
otherwise it will make your image 1 X 1 pixels. not big enough to see. -
Help: Factory Class using Inner Class and Private Constructor?
The situation is as follows:
I want a GamesCollection class that instantiates Game objects by looking up the information needed from a database. I would like to use Game outside of GamesCollection, but only have it instantiated by GamesCollection to ensure the game actually exist. Each Game object is linked to a database record. If a Game object exist, it must also exist in the database. Game objects can never be removed from the database.
I thought about making the Game object an inner class of GamesCollection, but this means that Game class constructor is still visible outside. So what if I made Game constructor private? Well, now I can't create Game objects without a static method inside Game class (static Object factory).
Basically what I need is a constructor for the inner Game class accessible to GamesCollection, but not to the rest of the world (including packages). Is there a way to do this?leesiulung wrote:
As a second look, I was initially confused about your first implementation, but it now makes more sense.
Let me make sure I understand this:
- the interface is needed to make the class accessible outside the outer classBetter: it is necessary to have a type that is accessible outside of GameCollection -- what else could be the return type of instance?
- the instance() method is the object factory
- the private modifier for the inner class is to prevent outside classes to instantiate this objectRight.
However, is a private inner class accessible in the outer class? Try it and see.
How does this affect private/public modifiers on inner classes?Take about five minutes and write a few tests. That should answer any questions you may have.
How do instantiate a GameImpl object? This basically goes back to the first question.Filling out the initial solution:
public interface Game {
String method();
public class GameCollection {
private static class GameImpl implements Game {
public String method() {
return "GameImpl";
public Game instance() {
return new GameImpl();
public static void main(String[] args) {
GameCollection app = new GameCollection();
Game game = app.instance();
System.out.println(game.method());
}Even if you were not interested in controlling game creation, defining interfaces for key concepts like Game is always going to be a good idea. Consider how you will write testing code, for example. How will you mock Game? -
Threaded inner classes & heap memory exhaustion
(_) how can i maximize my threading without running out of
heap memory?
push it to the limit, but throttle back before an
java.lang.OutOfMemoryError.
(_) within 1 threaded class ThreadClass, i have two threaded inner classes. for each instance of ThreadClass i only
start one instance of each inner class.
and, i start hundreds of ThreadClass, but not until the previously running ThreadClass object exits, so only one should be running at any given time.
so, what about threaded inner classes?
are they good? bad? cause "OutOfMemoryErrors"?
are those inner threads not dying?
what are common causes of:
java.lang.OutOfMemoryError: java heap space?
my program runs for about 5-minutes, then
bails with the memory error.
how can i drill down and see what
is eating-up all my memory?
thanks.A Thread class is not the same as a thread of
execution. Those inner class based threads of
execution are not dying.maybe. but this is the way i test a thread's life:
public void run() {
System.out.println("thread start");
System.out.println("thread dies and release memory");
}for each inner thread, and the outer thread, this approach for
testing thread life reveals that they die.
Why don't you use a thread pool?ok. i will think about how to do this.
>
If not, you need to ensure those inner threads have
exited and completed.what is a 100% sure check to guarantee a thread exits other than
the one i use above?
note:
the outer thread is running on a remote host, and the inner threads
are running locally. here are the details:
public class BB implements Runnable, FinInterface {
public void run() {
// do some work on the remote machine
private void startResultsHandler(OisXoos oisX) {
ResultHandler rh = new ResultHandler(oisX);
rh.start();
public void startDataProxy(OisXoos oisX, String query) {
DataProxy dp = new DataProxy(oisX, query);
dp.start();
public class ResultsHandler extends Thread {
// runs locally; waits for results from servers
public void run() {
ObjectInputStream ois = new ObjectInputStream(oisX.input);
Set result = (Set) ois.readObject();
} // ____ class :: _ ResultsHandler _ :: class ____
public class DataProxy extends Thread {
// runs locally; performs db queries on behalf of servers
public void run() {
ObjectOutputStream oos = new ObjectOutputStream(oisX.output);
while(moreData) {
.... // sql queries
oos.writeObject(data);
StartResultsHandler(oisX);
} // _____ class :: _ DataProxy _ :: class _____
}now, the BB class is not started locally.
the inner threads are started locally to both service data requests
by the BB thread as well as wait for its results.
(_) so, maybe the inner threads cannot exit (but they sure look
like they exit) until their parent BB thread exits.
(_) yet, those inner threads have no knowledge that the BB
thread is running.
externalizing those inner thread classes will put 2-weeks of work
in the dust bin. i want to keep them internal.
thanks.
here this piece of code that controls everything:
while(moreData) {
FinObjects finObj = new BB();
String symb = (String) data_ois.readObject();
OisXoos oisX = RSAdmin.getServer();
oisX.xoos.writeObject(finObj);
finObj.startDataProxy(finObj, oisX, symb);
