Default class access modifier
What is the default access modifier for a class? I can't seem to find it in the tutorials...
Thanks
Jim
The default access is the same for top level classes that do not specify access explicitly as for other identifiers. Package.
This single source file will create two class files in the same package. Only other classes in the package can see these top level package access classes.
And, yes, this is a bad idea. In the case of some build tools, errors in a compile can cause the public class to compile, but the package class to fail. After that, the compiler will not be able to determine what source file to compile for the package level class. This is an error that confuses many developers. I do not recommend this practice. Put each top level class in its own source file.

Why java class cannot have private and protected access modifiers?
class X {
private class y {}
}should compile just fine. A top-level private class makes no sense because you wouldn't be able to see it. As for protected, I don't know. -
I dint understood the below question properly, please help me out.......
You want subclasses in any package to have access to members of a superclass. Which is
the most restrictive access that accomplishes this objective?
A. public
B. private
C. protected
D. transient
E. default access
I want to know whether the question is relating to class access modifiers or methods and variables of the classes...I didnt get you, please explain the topic properly.... I think classes can have only public and default as an access modifier, is it rite??? That's right. Look at [this,|http://java.sun.com/docs/books/tutorial/java/javaOO/accesscontrol.html] it will give you a better understanding of the topic than you'd get from me answering your question.

Access Modifiers, Package declaration
I created the following two classes in the same folder as two source files:
A.java
package abc;
class A{
B.java
package abc;
class B extends A{
When I tried to compile, A compiled successfully. But when compiling B, it gives an error Cannot find symbol for class A.... I think it should be visible as both class access modifiers are (default). Why do I get this error????
By the way if package declarations are removed from both classes then they compile successfully........i tried a lot..... does classpath affects compilation??? can u correct dis???If we're going to make the effort to help you, you could show willing and make the effort to spell out all your words and generally make your sentences as easy to understand as possible.
Yes, the classpath affects compilation as the link provided shows. YOU can correct this.
>
e:\one\>javac -classpath e:\one\cert B.java

The classpath points at directories (or JAR files) not Java source files. Read the link. -
Default/package/none access modifier
Hi,
I was hoping for some discussion on the default/package/none access modifier. It's always really bugged me that we have public, private, protected, and then "none", while it seems to me that it would be less confusing, and more consistent to use the keyword "package", or maybe even "default".
Then, source code would look like
public class MyClass{
public int getValue() {}
private void setValue() {}
protected void someMethod() {}
package int justForPackage() {}
}I know this concept has come up before, but the books I've read which mention this topic haven't offered any actaul justification/explanation for why there isn't some keyword.
Anyway, are there any insights as to why java is this way, and any reasons why java should or shouldn't be changed to include the package access modifier.A good example is within a tightly grouped package (usually should be this way) you may have some cooperative classes that access methods.
// one .java file
public class SomeHelper {
private void method() {
new ClassForUsers().accessHiddenLogic();
// next .java file in same package
public ClassForUsers {
/* default-access */ void accessHiddenLogic() {
}But, you may want to allow users to subclass your ClassForUsers, without giving them access to the hidden logic method directly:
// another .java file in a different package
public class UsersSubclass extends ClassForUsers {
public void userMethod() {
// can't do this
accessHiddenLogic();
}This could be for either business logic or security reasons. So, package level access can be very useful. However, I've seen that in practice it is avoided because it isn't obvious what is going on. -
Hello,
Can someone tell me what the default access modifier is in Java:
-for methods
-for member variables
Thanks in advance,
BalteoFriendly. Accessible to any other classes in the package.

Private, protected Access Modifiers with a class
Why cant we use private and protected access modifiers with a class?
Thanks.Matiz wrote:
>
Public access allows you to extend a parent class in some other package. If you only want users to extend your class rather than instantiate it directly, make the class abstract and design for extension.Agreed. However, would the same argument be not true for the default access at the class level? No. Default access would only allow you to extend a parent class in the same package (as opposed to some other package).
Now my confusion is why is a class allowed default access at the top level and not protected?Because protected for a top-level class makes no sense. The protected keyword provides member access to any other class in the same package and extending classes outside the package. A top-level class isn't a member of a class, by definition, so there's nothing that protected would do provide differently than public.
So, the two access modifiers for a top-level class are public and default. Public allows access to the class outside the package, whereas default restricts access to the class within the package.

Usage of default access modifier
Some programmers don't use the default access modifier (package level). Is there a specific reason? If so, what is it? Or is it a good to use default access modifier?
Thank you,
SrikanthSome prefer to grant or limit access to an object by the interface they expose. In this case all methods are either public or private. Access is restricted based on the fact that only the appropriate code is given references of certain interface types and if code does not have the right interface, they can not access the method.
Its a different style, but I use it myself quite a bit. This way I never am concerned over if it should be public,private, protected or default. The choice is simpler. But sometimes it can make you create interfaces for really simple things which I am not uptight enough to do... -
Default bind access on class fields?
Hi,
I have a question on binding. Look at the following code:
1 var readyLight = Circle {
2 centerX: 12
3 centerY: 12
4 radius: 12
5 stroke: Color.GRAY
6 fill: bind RadialGradient {
7 centerX: 8
8 centerY: 8
9 radius: 12
10 proportional: false
11 stops: [
12 Stop {
13 offset: 0
14 color: Color.WHITE
15 }
16 Stop {
17 offset: 1
18 color: if (readyButton.selected) Color.GOLD else Color.GRAY
19 }
20 ]
21 }
22}This circle uses a radial gradient to fill itself. The 18th line uses a condition statement to dynamically determine the color of the second stop of the gradient. However, I think this line should use a "bind" keyword to keep the color dynamic. But when I added a bind the 18th line, an error showed up:"color has script only (default) bind access in javafx.scene.paint.Stop". I am confused about this, I haven't seen any document saying the "default bind access" thing.
This demo is from the official online UI tutorial: http://java.sun.com/javafx/1/tutorials/ui/layout/index.html
Any help on this is appreciated!This works because you are creating a new RadialGradient instance whenever selected changes. You are not just changing the color.
It would be more efficient to define a selectedGradient and an unselectedGradient and use them:
def selectedGradient : RadialGradient = RadialGradient {
centerX: 8
centerY: 8
radius: 12
proportional: false
stops: [
Stop {
offset: 0
color: Color.WHITE
Stop {
offset: 1
color: Color.GOLD
def unselectedGradient : RadialGradient = RadialGradient {
centerX: 8
centerY: 8
radius: 12
proportional: false
stops: [
Stop {
offset: 0
color: Color.WHITE
Stop {
offset: 1
color: Color.GRAY
def readyLight = Circle {
centerX: 50
centerY: 50
radius: 12
stroke: Color.GRAY
fill: bind if (selected) selectedGradient else unselectedGradient

Access modifier for Constructors ???
As constructors are not the so called Members of a class
(Class's Member declarations include only 4 things : variables , methods, member classes and member interfaces)
Why do we have access modifiers for constructors also ??
I know that if a class A 's constructor is declared 'private' , then that class cannot be instantiated outside the class A. .That is, class A can be instantiated only inside class A and provide this newly created reference to the outside world through public getter method.
I dont understand how the other access modifiers (protected and default ) apply to a constructor.
Any help from ur side is greatly appreciated !!!!!Why do we have access modifiers for constructors also
??To prevent anyone from accessing them if they shouldn't.
I know that if a class A 's constructor is declared
'private' , then that class cannot be instantiated
outside the class A. Or you use another c'tor. Or a static getInstance() method provided by A. You you simply shouldn't create an instance yourself anyway.
That is, class A can be
instantiated only inside class A and provide this
newly created reference to the outside world through
public getter method.Yepp.
I dont understand how the other access modifiers
(protected and default ) apply to a constructor. Same as at other places. No difference. -
What is the difference between access specifiers and access modifiers?
what is the difference between access specifiers and access modifiers? are they same? if not what is the difference.
Access Specifier are used to specifiy how the member variable ,methods or class to other classes.They are public ,private and protected.
Access Modifier:
1.Access
2.Non Access
Access:
public ,private,protected and default.
Non Access:
abstract,final,native,static,synchronized,transient,volatile and strictfp -
Default class map is dropping all Packets
Hello I have a Cisco 871 router that used to have Access list based security. now I am trying the ZBFW for the first time. I thought I had a pretty good program until I found all my traffic was getting dropped. This is my first stab at ZBFWs and I am a bit confused esp with the default class part. Any help is greatly appreciated!!!!
The router is for my house and thus also has to have priority for gaming. I will add the gaming and voice QOS once I get it working,

I would recomend you to investigate a little bit more about how the ZBFW features works
Now I am going to help you on this one at least, then I will give you a few links you could use to study
We are going to study traffic from MyNetNet-zone to the MyNetWan-zone
First the zone-pair
zone-pair security MyNetNet->MyNetWAN source MyNetNet-zone destination MyNetWAN-zone
service-policy type inspect MyNetNet-zone_to_MyNetWAN-zone_policy
so lets go policy-map
policy-map type inspect MyNetNet-zone_to_MyNetWAN-zone_policy
class type inspect MyNetNet-Class
inspect
class class-default
Finally to the class map
class-map type inspect match-all MyNetNet-Class
match class-map MyNetNet-access-list
match class-map Voice-protocols
match class-map Extended-protocols
match class-map Base-protocols
That keyword MATCH-ALL is the one causing the issues!!
Why?
Because you are telling the ZBFW to inspect traffic only if matches all of those class-maps so a packet will need to math the base protocols and the extended protocol and as you know that is not possible ( Just one protocol )
So here are the links

Custom class loader and local class accessing local variable
I have written my own class loader to solve a specific problem. It
seemed to work very well, but then I started noticing strange errors in
the log output. Here is an example. Some of the names are in Norwegian,
but they are not important to this discussion. JavaNotis.Oppstart is the
name of my class loader class.
java.lang.ClassFormatError: JavaNotis/SendMeldingDialog$1 (Illegal
variable name " val$indeks")
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:502)
at java.lang.ClassLoader.defineClass(ClassLoader.java:431)
at JavaNotis.Oppstart.findClass(Oppstart.java:193)
at java.lang.ClassLoader.loadClass(ClassLoader.java:299)
at java.lang.ClassLoader.loadClass(ClassLoader.java:255)

at JavaNotis.Notistavle.access$900(Notistavle.java:59)
at JavaNotis.Notistavle$27.actionPerformed(Notistavle.java:427)
JavaNotis/SendMeldingDialog$1 is a local class in the method
JavaNotis.SendMeldingDialog.init, and it's accessing a final local
variable named indeks. The compiler automatically turns this into a
variable in the inner class called val$indeks. But look at the error
message, there is an extra space in front of the variable name.
This error doesn't occur when I don't use my custom class loader and
instead load the classes through the default class loader in the JVM.
Here is my class loading code. Is there something wrong with it?
Again some Norwegian words, but it should still be understandable I hope.
protected Class findClass(String name) throws ClassNotFoundException
byte[] b = loadClassData(name);
return defineClass(name, b, 0, b.length);
private byte[] loadClassData(String name) throws ClassNotFoundException
ByteArrayOutputStream ut = null;
InputStream inn = null;
try
JarEntry klasse = arkiv.getJarEntry(name.replace('.', '/')
+ ".class");
if (klasse == null)
throw new ClassNotFoundException("Finner ikke klassen "
+ NOTISKLASSE);
inn = arkiv.getInputStream(klasse);
ut = new ByteArrayOutputStream(inn.available());
byte[] kode = new byte[4096];
int antall = inn.read(kode);
while (antall > 0)
ut.write(kode, 0, antall);
antall = inn.read(kode);
return ut.toByteArray();
catch (IOException ioe)
throw new RuntimeException(ioe.getMessage());
finally
try
if (inn != null)
inn.close();
if (ut != null)
ut.close();
catch (IOException ioe)
}I hope somebody can help. :-)
Regards,
Knut St�reI'm not quite sure how Java handles local classes defined within a method, but from this example it seems as if the local class isn't loaded until it is actually needed, that is when the method is called, which seems like a good thing to me.
The parent class is already loaded as you can see. It is the loading of the inner class that fails.
But maybe there is something I've forgotten in my loading code? I know in the "early days" you had to do a lot more to load a class, but I think all that is taken care of by the superclass of my classloader now. All I have to do is provide the raw data of the class. Isn't it so? -
Java inner class access specifiers
public class MyClass1 {
public static void main(String argv[]){ }
/*Modifier at XX */ class MyInner {}
What modifiers would be legal at XX in the above code?
1) public
2) private
3) static
4) friendIam a newbie to javaI don't care. I still assume you have a brain and expect you to use it.
and iam struck with this
question, iam getting a compile time error for any
access specifiers mentioned as options, but the
answers given by my superior are 1,2,3, are
correct..Then you made a typo or whatever. Make sure you eliminate the problems that are not "illegal access modifier" errors.
What good is knowing the reply to this if you can't even write an example?
