I am new to Netbeans and I am given a simple exercise by my professor to find the compiler errors in a given program. This is a simple hello world program but all I get is
Compiling 1 source file to D:\UCC\CS6312-Mobile Devices and Systems\Lab\MyFirstMIDlet\build\compiled
D:\UCC\CS6312-Mobile Devices and Systems\Lab\MyFirstMIDlet\src\myfirstmidlet\MyFirstMIDlet.java:12: error: ';' expected
form.addCommand(exit)
1 error
D:\UCC\CS6312-Mobile Devices and Systems\Lab\MyFirstMIDlet\nbproject\build-impl.xml:359: Compile failed; **see the compiler error output for details.**
BUILD FAILED (total time: 0 seconds)
So I want to know where I can find the details of the compiler errors as I have to include those in my assignment. Thank you
The compile error is the first bit of the error message:
D:\UCC\CS6312-Mobile Devices and Systems\Lab\MyFirstMIDlet\src\myfirstmidlet\MyFirstMIDlet.java:12: error: ';' expected
form.addCommand(exit)
This could mean exactly what it says, and that you're missing a semicolon on this line, but doesn't necessarily - it might be something else that's wrong that's causing the compiler to produce that error. You may also run into the case where you fix that error then have to fix some others that come up afterwards - such is the nature of compilers!

Getting below error when I am trying to run gatling.sh file. From my understanding getting compilation issue in RecorderSimulation.scala file while doing gatling.sh. Please see the below Error and help me

This error is due to the size of the scala file being too large. You need to keep number of requests in a method to under 100. I faced the same issue and resolved it by splitting the script into two methods.
You've managed to generate some piece of code that's too large with regard to the Scala language spec.
Please make sure you're using latest Gatling version (3.3.1 as of now) and upgrade if not.
If problem still happens, please reach out on Gatling community mailing list and provide your code.
I recently updated to AnyLogic PLE 8.4.0 and Java SE 12 on my Windows 10 laptop. And now an AnyLogic model that used to work earlier stops with the error "The method getJComponent() is undefined for the type ShapeTextField." I looked it up in AnyLogic/Help and I notice that getJComponent is identified as "Deprecated" and no alternative is identified. It appears to me that some mismatch happened between AnyLogic and Java updates that resulted in this error. I would appreciate any workarounds to get the model working.
Tried replacing getJComponent() with the following:
by getX() - gave error "cannot cast from double to Jtextfield"
by getPresentable() - gave error "cannot cast from Presentable to Jtextfield"
by getClass() - gave error "Description: Cannot cast from Class to JTextField."
by getComponentGraphics() - gave error "Description: The method getComponentGraphics() is undefined for the type ShapeTextField."
by equals - gave error "Description: The method equals(Object) in the type Object is not applicable for the arguments ()."
The code is:
((JTextField)(editbox.getJComponent())).setHorizontalAlignment(JTextField.LEFT);
This is defined in Simulation - Simulation Experiment / Java Actions/ Initial Experiment Setup field
Expected result: No error message. And the model should proceed to run window.
Thanks to the inputs from #Benjamin and #Felipe the following worked:
I replaced the editbox and buttons with corresponding artifacts from
AL8.4 palette. I copied the code from the earlier artifacts to
corresponding fields in the new artifacts. I deleted the artifacts
that were from AL7.
I commented out the line that was meant to align the editbox since
that capability is not available anymore.
With the above two changes I didn't get the error message about undefined method. The editbox and buttons worked and allowed me to enter XML filename and reading it with an XML parser routine. I have now run into issue with JAXB integration with AL8.4 and haven't been able to get past that yet. I will be posting that as a separate question.
I am using JFlex + BYACC/J to parse a small language.
Everything works but the error message for any syntax error (yyerror) is simply
"Error: syntax error".
Is there any (easy) way of generating more verbose error messages? The -v (verbose) flag only generates a y.output file with a description of the state machine.
Goal is to have error messages such as: "Expected X before Y but found Z" or something similar.
EDIT (w.r.t comments):
Above goal can be achieved in Bison but it does not solve my problem with BYACC/J
I am working on an android app which has worked and been tested many times. Today, however, in attempting to run the application for further testing, I have encountered the following error message:
C:\Users\1000\AndroidStudioProjects\WarofSol\app\build\generated\source\r\debug\com\blacktentdigital\warofsol\R.java
Error:(1251, 32) error: identifier expected
Error:(1251, 34) error: illegal start of type
Error:(1251, 35) error: identifier expected
Error:Execution failed for task ':app:compileDebugJava'.
Compilation failed; see the compiler error output for details.
>Information:BUILD FAILED
The problem is in the R.java file (as listed above). It is a generated file, so I've never touched it.
The offending line is this:
public static final class drawable {
public static final int 3=0x7f020000;
Hover over the offending line gives the following warning: "Identifier expected | Unexpected token"
Comparisons to other R files reveal that the "3" is not supposed to be a 3, and is evidently corrupted.
Attempts to replace the line or file with older backed-up versions have failed to produce any result because (evidently) the file is regenerating the wrong way each time I attempt the build, and I have no idea what might cause this. As I say, the problem sprang up suddenly without any provocation of which I am aware.
I've also attempted closing the program and restarting the computer to no avail.
Any ideas as to what might cause this and how it might be fixed?
I did get the Same error when i have defined a String in xml file like this.
<string name="3">Settings</string>
Error:
Error:(1426, 32) error: <identifier> expected
Error:(1426, 34) error: illegal start of type
Error:(1426, 35) error: <identifier> expected
Error:Execution failed for task ':app:compileDebugJava'.
> Compilation failed; see the compiler error output for details.
Information:BUILD FAILED
Solution: Resource name must begin with character.
So i have just change String like <string name="S3">Settings</string> and it worked.
So just check if you have any resource name 3 in all your resource file(string.xml, style.xml, attrs.xml) and folder(drawable, layout).
This is a quote from java documentation:
A variable's name can be any legal identifier — an unlimited-length sequence of Unicode letters and digits, beginning with a letter, the dollar sign "$", or the underscore character "_".
And you named drawable with digit, that caused the problem.
I downloaded core.odex and framework.odex from my Samsung Galaxy Player, in order to make some changes for the hidden apis, following this webpage: https://devmaze.wordpress.com/2011/01/18/using-com-android-internal-part-2-hacking-around/
Also, I got baksmali and smali from here: http://forum.xda-developers.com/showthread.php?t=1650243
Now, when I run the command: java -jar baksmali-1.3.3.jar -c :core.odex -x framework.odex, the following error appears:
