While local variable initialized inside try block compiler throws error???
Check out this code where two local variables(one String and the other int type) is declared at the beginning of the method and initialized inside try block. now when i compile this app, it gives an error sayin' that Variables not been initialized. Can anyone tell me why compiler is throwin' an error message?
Many thanks.
import java.io.*;
public class Test{
public static void main(String[] args){
String aa;
int c;
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("EnterAnything:");
try{
aa = in.readLine();
c = 1;
catch(IOException e){
System.out.println(e.getMessage());
System.out.println(aa);
System.out.println(c);
}
jfbriere,
Thanks to u all.
that every reference to the variable is necessarily preceded
by execution of an assignment
to the variable.But I've initialized the variable c and aa inside try block before referencing it as a parameter of println()?
Can u clarify this?

Return statement inside try block
what is wrong if i write code like as below...please explain me since i am new to java
class sample{
public String method(){
try{
String str="abc";
return abc;
catch(Exception e){}
}veldhanas wrote:
return abc;In your code there is no varible declared as abc. It is a value assigned in str.
Suppose if the code in try statement throws exception the return statement is skipped and the
associated catch block will get executed. So your catch block must return a result of type String.... or throw another (or the same) exception.
In this case, since there's no way the code in the given "try" block can throw an exception, it would have been better to not even have a try/catch block in the first place.
And almost never just swallow exceptions like that (an empty catch block). There are only a few cases where it's ok to swallow them (such as in finally blocks where you're cleaning up resources which may throw exceptions while cleaning up, and you want to continue cleaning up and ignore those kinds of exceptions). -

Threads: t.stop()
JVM : System.exit()
which one can really help and where?What if security Manager comes into picture?
class ExitCatchingSecurityManager extends SecurityManager
public void checkExit(int status)
Process.terminateProcessWithThreadGroup(getThreadGroup());
throw new SecurityException();
What if an application calls System.exit()?
We still have one big hole in our multiprocess library. If any application calls System.exit(), the JVM terminates, and all the pseudo-processes will be destroyed with no warning. Fortunately, Java's design once again comes to our aid. Any call to System.exit() is first checked by the SecurityManager to see if the application has permission to terminate the JVM. We can install our own SecurityManager to catch the System.exit() call, disallow it, and terminate the pseudo-process instead. The SecurityManager is actually quite simple to define:
class ExitCatchingSecurityManager extends SecurityManager
public void checkExit(int status)
Process.terminateProcessWithThreadGroup(getThreadGroup());
throw new SecurityException();
In addition, the SecurityManager should define all other checks so that they do not block pseudo-processes from running. A simple null call for all check* methods will work. We install our own SecurityManager by calling System.setSecurityManager(), i.e., by adding the following line near the startup of the multiprocess library:
System.setSecurityManager(new ExitCatchingSecurityManager());
The Process.terminateProcessWithThreadGroup() method is simple to define, by holding a collection of Process objects in the Process class, searching the collection to find the Process with the identical ThreadGroup, then terminating that Process. -
Can't throw exception inside try block!
Hi,
I'm having a problem trying to throw an error inside a try block.
To illustrate:
public class TestException {
public TestException() {
try {
int ret = foo();
System.out.println("ret is " + ret);
} catch (Exception ex) {
System.out.println("exception caught");
public int foo() throws Exception {
int ret = 0;
try {
throw new Exception("test exception");
} finally {
return ret;
public static void main(String[] args) {
new TestException();
If I run this the only output is "ret is 0" - I do not catch the thrown exception! What am I doing wrong?
Any and all help will be very gratefully received.
Thanks.I need to correct myself: I've re-read the spec, and actually the behaviour is conformant with the JLS: JLS says that the return statement completes abruptly, and an abrupt return in a finally block that didn't have a (applicable or any) catch block will result in the original exception being 'forgotten'.
Very unintuitive, but as-spec'ed -
Txt file read in- StringTokenizer- Try Block Catch for errors
Hello
So I am having a few issues with a school project. First is with my ReadWithScanner. It does not read in the file giving me a NullPointerException error on the line <Scanner in = new>. I have tried a few other read in files and they do not seem to be working.
I am also stuck on the logic on the try block catch statement. How does a person set up a �custom� try block that looks for errors like the ones below? I have attempted to start in the commented code.
The text file has to read in 1000 individual lines of code and are separated by �;� and should be separated into tokens with the StringTokenizer class what I attempted to do below also. Both are mere attempts and need help�
This is some what of the logic I thought of doing
1.Read the first line in first with the scanner class
2.use delimiter separated by �;�
3.Tokenizer the line into separate tokens- invoiceCode, fName, lName�
4.Check classes- check Name, check Date, checkPrice, checkPrice, checkGenre, checkShippingDate invoiceCode = "Error Code" checkInvoiceCode(String invoiceCode)checkName(String name), checkPrice(String price), checkGenre(String genre)
5.Apply the regular expressions to each try block statement
a.Assign a letter to each error for example if invoice was to short it would be assigned a letter A
b.If invoice does have the right characters it would be assigned B
c.If name has to few words it would be assigned D
d.�
This is an example of a good field from the text file
XYG726;Smith,Mr. John M.;29.96;comedy;101008;100604
Not so good line
Lu15;Will, Mark;50.00;Science;030305;030807
The file should then be printed out in the program not to a text file. It only needs to print the invoice number and error code letter assignment.
If you have any questions feel free to let me know. Thanks for all or any help you have to offer.
Invoice
Three upper case letters followed by three digits
Regular Expression "[A-Z]{3}[0-9]{3}"
Customer Name
Should be in the form: last name followed by a <,> optional title (Mrs. Mrs�) then first name optional middle initial Titles must be
So regular expression something like �[a-z][A-Z]+([A-Z]{1}?[a-z][./})+[a-z][A-Z]�
Sale Price
Two decimal digits to the left of the decimal point. The price should not have a leading zero.
Regular Expression [0-9]{2}*./[0-9]
Genre
The genre should only contain lowercase letters. Regular expression �[a-z]�
ShipDate and Order Date-
Must be standard dates- MMDDYY. The order date and shipping date has to be after today�s date. Regular expression �[0-9]{2}+[0-9]{2}+[0-9]{2}�

Final variables and try blocks
If you tried to initialize a final variable within a try block, you would get a compile-time error.
Here's an example class:
class Example {
private final String example;
public Example() {
try {
example = "Example";
} catch (Exception e) {
// Just an example.
}Obviously you wouldn't need to try-catch something like this (it's a stupid example - I know) , but the point is, the code wouldn't compile, and would return an error saying something like "example may not have been initialized".
So I've got two questions. Why is this, and is there any way around it?
Thanks in advance :)Why is thisThe actual error message is "The blank final field example may not have been initialized". The Java compiler insists that all the fields have some actual value when a constructor has done its thing. Nonfinal fields will have the "default" value of null, but this is not so for final fields: if they had a default value, you couldn't change them from that default because they're final!
Once you enter a try block the compiler has no way of knowing that the assignment line will ever get carried out. Some exception might occur and the example field would be left uninitialised ie having no value whatsoever, not even null.
is there any way around it?In the catch part you could throw the exception and let the caller deal with it.
Or you could try and assign some value to example within the catch part. Now the compiler will complain "The final field example may already have been assigned". Supposing you wanted it to end up as null in this case (it's not clear why though... But you may have a sensible "default" if for example a file can't be written to or some other exceptional state has occured)
class Example {
private final String example;
public Example() {
String str;
try {
str = "Example";
} catch (Exception e) {
str = null;
example = str;

Is volatile necessary for variables only accessed inside synchronized block
Hi,
I am using ExecutorService to execute a set of threads. Then the calling thread needs to wait until all of them are done to reuse the thread pool to run another set of threads (so I can't use the ExecutorService.shutdown() to wait for all of the threads at this point). So I write a simple monitor as below to coordinate the threads.
My question is: will it work? someone suggests that it might not work because it will busy spin on the non-volatile int which may or may not be updated with the current value from another thread depending on the whims of the JVM. But I believe that variables accessed inside synchronized blocks should always be current. Can anyone please help me to clarify this? Really appreciate it.
* Simple synchronization class to allow a thread to wait until a set of threads are done.
class ThreadCoordinator{
private int totalActive = 0;
public synchronized void increment(){
totalActive++;
notifyAll();
public synchronized void decrement(){
totalActive--;
notifyAll();
public synchronized void waitForAll(){
while(totalActive != 0){
try{
wait();
}catch (InterruptedException e){
//ignore
}Don't do that. Just save the Futures returned by the ExecutorService, and call get() on them all. This will only return when all the tasks have finished.

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.

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

InputStream inn = null;
try
JarEntry klasse = arkiv.getJarEntry(name.replace('.', '/')
+ ".class");
if (klasse == null)
throw new ClassNotFoundException("Finner ikke klassen "

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? -

hi everyone ,
i am creating a button but it will show that local variable hides a field . this not an error or warning
JRadioButton a1Btn = new JRadioButton("Physical connectivity");
a1Btn.addActionListener(this) ;here a1Btn shows local variable hides a field.Correct, it is not an error to have a local variable with the same name as a field of the class.
IDE's such as Eclipse often have options that will flag such name shadowing as a warning, so you'll know when you accidentally do this.
But note that you can always access the class's field by prepending "this.", for example, "this.a1Btn". -

Edited by: wannaBeACsGrad on Jan 10, 2008 9:09 AMI am not sure what your are trying to do. Your code as posted is incomplete and could not possibly compile. The Try/catches do not seem to be nested.
More importantly, why in the world would you ever want to have a try inside a try? You can have a single try, then several different calls in loops or whatever that can potentially throw Exceptions and then have mulitple catch statements to handle them. For instance, you could have something like this:
try {
} catch (NullPointerException ne) {
// handle null issues here
} catch (NumberFormatException nfe) {
// handle number format issues here
} catch (Exception e) {
// everything else falls here
}Keep in mind that you don't want to do any "Error Hiding". Make sure you handle each case appropriately. -
VerifyError: Illegal local variable number. Class compiled, but run failed
Environment:
Visual Age for Java 3.5.3 (compiles to 1.2.2 class files)
Runtime is the JRE 1.3.1 plugin.
I have a class that VA compiles without problem,
but when I use the compiled jar, the VM fails with
the error
java.lang.VerifyError: (class: <completeClassName>, method: <myMethod> signature: (Ljava/lang/Object;)F) Illegal local variable number
at <rest of stack trace>
I traced it back to the following piece of code:
// produces failure
BlockLabel: do
if (true) break BlockLabel; // disable block for testing
while(true==false);
// produces no failure
BlockLabel: do
// if (true) break BlockLabel; // stay with test
while (true==false);
I am using these constructs
with a labeled block,
the do{..}while(true==false);
and if(true) break BlockLabel;
in lots of places in my code
and it never produced any problems.
So the VerifyError for "Illegal local variable number" must be due to some other reason. Can anyone shed some light on this? I have scanned the bug parade and have found VerifyErrors, but none with explicit mention of "illegal local variable number".
Thanks, SylviaHow long is the method that this code is in?

If you are getting at JMS Sender communication channel, try to stop and start the JMS communication channel and see the status, also use XPI Inspector to get the exact error log.

Hi everyone,
I just installed SP09 and i was testing the solution. And I found a problem with the approvals tasks.
I configured a simple ROLE approval task for validate add event. And when the runtime executes the task, the dispatcher log shows a error:
ERROR: Evaluation of approvalid failed with Exception: while trying to invoke the method java.lang.String.length() of an object loaded from local variable 'aValue'
And the notifications configured on approval task does not start either.
The approval goes to the ToDO tab of the approver, but when approved, also the ROLE stays in "Pending" State.
I downgraded the Runtime components to SP08 to test, and the approvals tasks works correctly.
Has anyone passed trough this situation in SP09?
I think there is an issue with the runtime components delivered with this initial package of SP09.
Suggestions?Hi Kelvin,2016081
The issue is caused by a program error in the Dispatcher component. A fix will be provided in Identity Management SP9 Patch 2 for the Runtime component. I expect the patch will be delivered within a week or two.
For more info about the issue and the patch please refer to SAPNote 2016081.
@Michael Penn - I might be able to assist if you provide the ticket number

Hello,
I am trying to extract data out of a while loop as my declarations update with respect to the iteration number. I have attempted to use both local variables and shift registers, but with no luck.
I have also done the following example: http://www.ni.com/white-paper/7585/en and it works like a charm.
I attached the PNG file with local variable declaration circled in red. Will attach a VI in the next respnose.
Thanks
Solved!

Can you explain what it is supposed to do? What's the purpose of the value property node read which only seems to update an indicator.
The inner while loop should proably be a FOR loop, because the number of iterations is known before the loop starts.
Your use of formula nodes seems overly complicated.
