  • How to compile programs from this sites tutorial?

    Hi, so i'm reading the "GUI" tutorial on this website, it's great but when I compile the example "source codes" it gives me this error:
    Error: File is in the wrong directory or is declared part of the wrong package. Directory name 'Anna - java' does not match package name 'components'.
    So I get the source codes from this website: http://java.sun.com/docs/books/tutorial/uiswing/examples/components/index.html#ButtonDemo
    So say I get BorderDemo.java .... when I compile it it gives me this error: Directory name 'MyDocuments - java' does not match package name 'components'.
    How do I make it compile and run properly, and how can I ALSO compile it properly withOUT the package "components"?
    thanks.

    Error: File is in the wrong directory or is declared part of the wrong package. Directory name 'Anna - java' does not match package name 'components'.That error tells you all you need to know. You have to respect the existing directory structure, you can't change it. If they've put their code into a package called 'components' it has to be in directory called 'components'. Period. If you want to change that (a) you will have to change all the internal package names in the Java code, and (b) 'Anna - java' is not a legal Java package name.

  • How to Compile & Deploy the Java Concurrent Program File

    Hi,
    There is a requirement to create the Java Concurrent Program in Oracle eBusiness. I am able to create the Java Concurrent Program file. But unable to do the following things:
    1.Since it is custom file, which location I will deploy the file?
    2. How to compile the file?
    3. In the execution file path and executable file name what should I specify for JCP?
    Please guide me.
    Thanks

  • How to compile other java files and run them from my own programs?

    I'm developing a unit testing tool for AspectJ, which can originally generate the stubs for aspect unit to be tested. All these stubs are java files. After generation of stubs, how can I program the code to compile this unit together with these stubs, i.e. how can I put the functionality of compilation and run, e.g. command "javac *.java" and "java *", into my own code.
    Hope you can understand what I mean.
    Thank you in advance.

    When I use Runtime.getRuntime().exec(command) for executing the AspectJ compile command "ajc", "IOException createProcess error=2" always occurs, while it is ok for Java comiple command "javac".
    Why this happens when I use Runtime.getRuntime().exec("ajc Hello.java Test.aj")? Is it the reason that Runtime.exec(String) may not support any command in DOS?
    (ajc is the compile command for the java file and aj file.)
    Thank you in advance.

  • How to compile and execute lex,yac,c and java programs

    its the 3rd day on my New MacBook pro..
    as i just migrated from windows to mac i love to work on this..
    The main problem  is i DON't know .......
    how to compile and execute
    1) lex and yac programs
    2) c program
    3) java program
    so please help me
    THIS is the error i got   a1.l is a program
    i got the same error when i used  gcc
    $ lex a1.l
    $ cc lex.yy.c                                 
    Undefined symbols:
      "_yywrap", referenced from:
          _yylex in cc8QDQjW.o
          _input in cc8QDQjW.o
    ld: symbol(s) not found
    collect2: ld returned 1 exit status

    Is the problem that you don't know how to compile and execute these programs on a Mac, or just that you don't know how to compile and execute them?
    Mac OS X is really just a version of BSD Unix, as far as programs like like bison, flex and gcc are concerned...and even when Apple specific versions are provided in the Developer Tools, there are symlinks in the usual places in the Unix file hierarchy.
    For problems with lex and yacc, I suggest you start with their own references, for example, here.
    Or you could just use %option noyywrap, if you only have one file to scan.
    Or you could link to libfl.a using -lfl and use the default version from that library.
    But you really should (as Keith Barkley was subtly hinting at) learn how these tools work and why they work that way.

    You're trying to build something that depends on a library you don't have, or haven't referenced. This sort of question belongs in the Developer forums.

  • How to compile and run package programs in Java

    Hi,
    I want to know how to compile and run the package programs in Java using -d. instead of creating the package folder manually.
    eg:
    package Test;
    class test1
    public void disp()
    //Any code;
    I want to compile this without creating the folder ' Test ' manually. that is if we use -d with javac the Test folder will be created automatically. I need the format of -d

    My program Test.java in F:\Tomcat5\webapps\Ambika\WEB-INF\Classes. I compiled in the format below. I got like this. What should I do for this?

  • How come this program compiles?

    class Base
         Base()
              int i = 100;
              System.out.println(i);
    public class Pri extends Base
         static int i = 200;
         public static void main(String[] args)
              System.out.println(i);
              Pri p = new Pri();
    i get very confused here. in the main, the value of "i" will be printed to the standard output even before the class Pri is instantiated! how come this program can compile?
    your help will be very much appreciated.
    eileen2

    This is because your class Pri extends Base. Because you didn't specify any class Pri constructor, java automatilcally created a no-argument constructor of class Pri with a call to the superclass constructor Base(). You can validate this by adding another Base constructor with arguments and then removing the no-argument Base constructor. Pri() will not compile.

  • How to compile and run a .java file from another java program

    hello,
    can any one tell me how to compile and run a *.java* file from another java program which is not in same directory?

    Well a smarter way of implementing this is by using a solution provided by Java Itself.
    If you are using J2SE 6.0+ there is an in built solution provided along with JDK itself and inorder to go ahead with solution the below are set of API which you;d be using it for compiling Java Programs (Files)

    Now once we are done with compilation.In order to run a Specific class all you ought to do is create an object and its specific methods of a specified class included in the CLASSPATH which you can manage it easily by usage little bit reflections.
    Hope that might help :)
