Call(execute) a class in another class

Hi,
please I am a newbie in java and I want call and show the result of algorithm in a method of another class
the  algorithm that I use is apriori algorithmhttp://www2.cs.uregina.ca/~dbd/cs831/notes/itemsets/itemset_prog1.html, that algorithm should use two files like arguments:config.txt and transa.txt when I excute this algorithm in line command the algorithm output is file called apriori-output.txt so i want excuteafter show result of this algorithm inside a class called JadeProject and and more specifically in method called setup()
so how can call and execut this algorithm
thanks in advance

Hi gimbal2,
thank you for your reply,
My problem is the following:
my question is how can I execute the apriori algorithm inside the agent code (java class)
I want to build multi agent system using jade(framwork based in java language it is used to build multi agent system) my multi agent system is composed in many agents
those agents are juste java classes
My aim is to execute an algorithm(java class) in agent class
this algorithm is the data mining algorithm apriori http://www2.cs.uregina.ca/~dbd/cs831/notes/itemsets/itemset_prog1.html
the apriori algorithm use two text files :config.txt and transa.txt
i put the algorithm aprioir and the two files in the same directory and i compile the algorithm java class in line command
the output of the execution of algorithm is generating in text file called apriori-output.txt
but I am using netbeans and no line command
my question is how can I execute the apriori algorithm inside the agent code (java class)
thank you in advances

    Hi ..... can somebody plz tell me
    How to call a Java Class from another Java Class assuming both in the same Package??
    I want to call the entire Java Class  (not any specific method only........I want all the functionalities of that class)
    Please provide me some slotuions!!
    Waiting for some fast replies!!
    Regards
    Smita Mohanty

    Hi Smita,
    you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
    e.g.
    you have developed A.java and B.java, both are in same package.
    in implementaion of B.java
    class B
                A obj = new A();
                 //to access A's methods
                 A.method();
                // to access A's variable
                //either
               A.variable= value.
               //or
               A.setvariable() or A.getvariable()

  • Displaying the output from a java class executed from W/I another class

    I have compiled a java class, but I have run into a problem executing the class. I have read the posts and still have not solved the solution. I have tried to get the output of the Process by using "proc.getOutputStream().toString()", however it displays it in binary (ex. java.io.BufferOutputStream@48eb2067). If anyone can provide any assistance I would greatly appreciate it. Or if you could tell me if I'm on the right track or not. Thanks ALL. Here is a code segment:
    int truncStart = s.indexOf(".java");
                   s = s.substring(0,truncStart);
                   String[] command2 = {"java","c:/"+s};
                   try
                   //JOptionPane.showMessageDialog(null,"Exec. File "+s, "Exec. File : ",JOptionPane.ERROR_MESSAGE);
                   proc = Runtime.getRuntime().exec(command2);
                   JOptionPane.showMessageDialog(null,"Output: "+proc.getOutputStream().toString(),"Output"
    ,JOptionPane.ERROR_MESSAGE);
                   }

    You have to read the stream, like:
    InputStream stream = proc.getOutputStream();
    // now use methods on stream, such as read() to read the characters/lines - or wrap it in another line-friendly stream - see the java.io.* classes - keep reading until you get an end-of-stream indicator, depending on the API you end up using.

  • How can I call a java class from within my program?

    I was wondering if there's a platform independent way to call a java class from my program.

    Here's my scenario. I'm working on a platform independent, feature rich, object-oriented command prompt program. The way I'm designing it is that users can drop classes they write into my bin directory and gain access to the class through my program. For example, they drop a class named Network.class in the bin directory. They would type Network network at my command prompt and gain access to all the methods available in that class. They can then type system.echo network.ipaddress() at my prompt and get the system's ip address. I have it designed that there's a server running in the background and the clients connect to my port. Once connected the end-user can enter their user name and password and gain access to the system. When they type a command they actually call another java program which connects to my server using a seperate thread. They can then communicate back and forth. I have it set that everything has a process id and it's used to keep track of who called what program. Once the program is done it disconnects and closes. Rather than getting into the nitty gritty (I didn't want to get into heavy detail, I know how everything will work) I'm really interested in finding out how I can call a java program from my program. I don't want it to be part of the app in any way.

  • I want to call External Java class from the PL/SQL

    Hi,
    I am using Oracle Apps R11i (11.5.7), I wanted to call external Java class from the PL/SQL. This external Java class is residing in another application server.
    How do I do this.
    I know one way. Develop C routine in Oracle Apps to call external java class and call this C routine from the PL/SQL.
    Is there any simple method available? or any other method?
    Thanks in advance.
    -Venkat

    First of all, this is a Java application you're talking about, right (i.e. it has a main() function)? It's not just a class that you're trying to instantiate is it? If it's an application, you obviously have to start a new virtual machine to run it (rather than using the virtual machine built into the database like stored java). I'm a little leary of your mention of an "application server" as this would more commonly mean that a virtual machine is already over there running with access to this class. In which case, you'd typically interface with SOAP or some other RPC API.
    All that aside, as long as you have physical disc access (through NFS or whatever) to the class file, you could use a java wrapper class with a system call to do this. In fact, there is a thread in just the last day or so on this very forum that has the code to do just that (see " Invoking OS Commands from PL/SQL"). However, it's worth noting that the virtual machine will be running on the database server in this case and not the application server.

  • Jsp session variable to call in  java class.

    here i am facing a problem in calling a jsp session varibale to java class.
    in my code.. i have seperate files for jsp pages and packaged java classes.
    as i am developing a web tire application. the data entered in the front end i am getting to jsp page and putting the mandatory in session to use in other pages. now here the same session vaiable i have to use/call in java class file.
    Please refer me the best method and any references on this to call the session vaiable to java class file.
    in jsp page i decleared like this:
    session.setAttribute("stuIdentification",stuid);
    this id i have to use in java class.file.
    how to call it?
    Thanks
    Kurra

    Gimbal2's got the right idea.
    The reasons for choosing point 1) are also valid. Whenever possible try and do as much code that is not specifically tied to your business objects inside your dynamic element (the jsp page) instead of your static one (the compiled class)
    this allows you to very easily update your jsp to make any changes without having to recompile class code. Recompiling seems like a little thing when you are in development but imagine if the class is executed by a business critical application that faces forward to customers, recompiling will mean shutting down your servers and that may not be an option.

  • Getting the calling object reference / class?

    Dear forum members,
    Is it possible for A in the below example to get that B was the "caller"?
    class A {
      A() {
      public void someMethod(String text) {
        System.out.println("I was called with: " + text);
        System.out.println("I was called by: " + thatMagicWayToGetCallerClassOrReference());
    class B {
      public static void main(String[] args) {
        A a = new A();
        a.someMethod("HOLA HOLA");
    }

    Another way of getting the class of your caller is to use a SecurityManager object. getClassContext() is protected but you can get at it by subclassing SecurityManager (it works if you just instanciate the manager without installing it). This gives you a reference to the Class object itself where the stack trace returns only the class name. Bear in mind that the class in question will be several items up the array, the first entry is the SecurityManager itself, the second the called class.
    However, I agree with others it doesn't sound like the best design. If you're having trouble with not being able to change the interface specifications to pass the extra information then consider using a static reference, if necessary a ThreadLocal. What happens if you want to call the offending method indirectly through some central method at some future time? You've lost the call origin data.
    Why can't you simply add a parameter to the offending call?
