Passing arguments to a method

I need to pass an ip address into a method. So I know its type InetAddress. If the IPAddress is 10.100.50.33. how would I pass it in to the method. eg:
SysNameScanCommand( )Would it be like this?
SysNameScanCommand(InetAddress 10.100.50.33 )

It depends what kind of argument your function is expecting. If it wants a String, you could call
SysNameScanCommand("10.100.50.33");If it wants an InternetAddress object, then the call would be something like:
SysNameScanCommand(new InternetAddress("10.100.50.33"));

Trying to pass arguments into a method call and failing

Hi everyone, I'm fairly new to programming, and newer to Java. I'm currently working on a project that pulls fields from a database based on a name, and I'm having some trouble getting the connection string set up.
Statically defined, the database connects and the program logic that follows works just fine. The problem is that to future-proof this application, I need to pass the database URL, port, db instance, username, and password into the program as arguments from the batch file that will then be scheduled to run the program on a job-by-job basis.

        System.out.println(date); //print the date out to the console

        String sourcefolder=""; //we're going to load the job source folder into this variable based on the job's name
        String destfolder="";//same with this variable, except it's going to get the destination folder
        try {
            ResultSet rs = stmt.executeQuery("SELECT * FROM myschema.jobs WHERE NAME =\'"+args[0]+"\'");
            while ( rs.next() ) {
                sourcefolder = rs.getString("sourcefolder");
                destfolder = rs.getString("destfolder");

            System.err.println("SQLException: " + ex.getMessage());
            logError(args[0], ex.getMessage());
}That works, and it connects to the database and everything. But when I pass the variables in from the project properties run settings, I get the following exception:

Perhaps it's the way I'm escaping the quotation marks, but I put that same line inside a System.out.println() and it output it exactly as I had typed it in statically before, so I don't know what it could be.
I would really appreciate any advice. Thanks in advance for your time.

I think you're mixing up SQL and Java. The Java method expects the user name and password as separate parameters, not encoded in one String. So you shouldn't be concatenating args[9] and args[10] at all, they should remain as separate parameters.
The call should be:DriverManager.getConnection("jdbc:oracle:thin:@" + args[6] + ":"+ args[7] + ":" + args[8], args[9], args[10]);
                                                 parameter 1                                  2         3

Passing arguments to java methods

i Haver been reading the java web page on this, yet am still miffed about what happening. heres the code
   class A {
        public int x;
        A(int x) {
            this.x = x;
        public String toString() {
            return Integer.toString(x);
    public class CallDemo2 {
        static void f(A arg1) {
            arg1 = null;
        public static void main(String args[]) {
            A arg1 = new A(5);
            f(arg1);
            System.out.println("arg1 = " + arg1);
    }The above code prints out 5, i think i understand that because of the local method can just be seen to be intitalling the value. The calling method in the main also something like the value gets passed back not the memory location so therefore doesnt effect the value 10.
Now the below code is what confuses me
class A {
        public int x;
        public A(int x) {
            this.x = x;
        public String toString() {
            return Integer.toString(x);
    public class CallDemo3 {
        static void f(A arg1) {
            arg1.x = 10;
        public static void main(String args[]) {
            A arg1 = new A(5);
            f(arg1);// why does 10 get printed out and not 5 ?
            System.out.println("arg1 = " + arg1);
    }

Passing arguments to main method from a shell script

The main method of my class accept more than 10 arguments so my shell script execute this class like this :
java -cp xxxx mypackage.MyClass $*
The problem is that some of those arguments allows spaces. When i execute this script like this :
myscript.sh firstparam secondparam ...... tenthparm "eleventh param"
or
myscript.sh firstparam secondparam ...... tenthparm 'eleventh param'
the java class consider that my eleventh param is 'eleven' and not 'eleventh param'
The same class works well with an equivalent dos script.

I had this problem once also, and I found there are several ways to fix it. One way is to replace all of the spaces in the arguments with _ characters, or you can concantate all of the arguments into one String at runtime (with spaces in between) and use code to separate the arguments out. With the quotation marks, this code would be simple. If the spaces in one argument are used to divide different parts of the argument, just make them spearate arguments.

How to pass argument to the Java Plugin JVM w/o using the Control Panel?

I want to deploy an applet to be loaded by the Java Plug In
and fix some settings of its Java Virtual Machine.
The JPI Control Panel offers two ways to pass arguments to the JVM,
none satisfactory.
1. while interactive via the Control Panel Window.
This cannot be a solution for a deployed applet.
or
2. by editing the system generated file that stores
the settings of the Plugin Control Panel, using a property
named javaplugin.jre.params.
The problem with this method is that if forces to access
and edit this property file which is stored at various locations
depending the client platform. Then, it may collide with other
settings for other applets.
Is there a way to pass the arguments to the JVM
from within the html file?
Has anyone found a solution to this question?
JPS

I am interested in this issue as well.
Did anyone find a reliable way to specify the runtime parameters that should be used by the Java Plug-in in order to execute a given Java applet?
I believe a good place to specify these runtime parameters would be the applet's JAR manifest: only digitally signed applets should be able to set the desired runtime parameters...
Any comments / suggestion would be greatly appreciated.
Regards,
Marco.

Creating pocess intance of a different process and passing arguments

Creating Process instance of a different process:
I have two different process: Main_Flow (id: MainFlow) and Second_Flow (id: SecondFlow). In the first process I am reading a csv file. Each line of the file has four columns. After reading each line I have to initiate Second_Flow and pass the read data from the file. (Pls find the code below for the whole process):
     fileReader = FileReader(arg1 : fullFileName);//filename is of file type and have file name and path
     Java.Io.BufferedReader reader = BufferedReader(arg1 : fileReader);
     String str;
     int countLines = 0;
     while ((str = reader.readLine()) != null)
          strColumn = str.split(delim : ",");
               int ColumnCnt = 0;
               while (ColumnCnt < 4)
                    //defining variables
                    String appNo;
                    String custNo;
                    String loanAmm;
                    String loanDate;
                    //logMessage("Value at Column: " + ColumnCnt + " is " + strColumn[ColumnCnt]);
                    if (ColumnCnt == 0)
                         arrLoanData["appNo"] = strColumn[ColumnCnt];
                    else if (ColumnCnt == 1)
                         arrLoanData["custNo"] = strColumn[ColumnCnt];
                    else if (ColumnCnt == 2)
                         arrLoanData["loanAmm"] = strColumn[ColumnCnt];
                    else if (ColumnCnt == 3)
                         arrLoanData["loanDate"] = strColumn[ColumnCnt];
                    arrLoanData["descriptionArg"] = "AutoInstance: " + formatTime('now', timeStyle : Time.SHORT);
                    arrLoanData["genByArg"] = "Automatic";
                    ProcessInstance.create(processId : "/SecondFlow", arguments : arrLoanData, argumentsSetName : "BeginIn");
                    ColumnCnt = ColumnCnt + 1;
          countLines = countLines + 1;
(“The code is in Java and not in PBL”)
I have to pass appNo, custNo, loanAmm and loanDate as the arguments. The Argument will be of Any[String] type. The argument set name of Second_Flow is “BeginIn”. But I am not getting anything in Second_Flow.
What can I do in the argument mapping of begin of Second_Flow to get the passed argument (array)?

the argument 'arguments' for the method ProcessInstance.create receives a map of the arguments that the 'argumentSetName' argument set will receive.
so for example if your second flow has 2 arguments, String name, Decimal value and String[] content your method invocation would be:
ProcessInstance.create(processId : "/SecondFlow", arguments : {"name": strNameFromCsv, "value": valueFromCsv, "content": ["a","b","c","d"]}, argumentsSetName : "BeginIn");

How to pass argument in main function ?

How to pass arguments in main function of one class from another class ?
I don't want to pass argument from command prompt.
I want to try something like this -
class Test{
public static void main(String args[]){
for(int i=0;i<args.length;i++)
     System.out.println(args);
class Fun{
public static void main(String args[]){
     Test t=new Test("Hello","good bye");
when i run Fun class it gives error.
Suggest me how can i do that.

In Fun class main method does not take arguments that is fine. In Test class instead of main method you can have constructor to take input parameters as suggested by BalusC
However, if you want to make your existing code work, you can call (though not appropriate) main() method of Test class from main() method of Fun class (As main() method is static object is not required to invoke this):
Test.main(new String[]{"Hello","good bye"});Here is your code:
class Test{
public static void main(String args[]){
for(int i=0;i<args.length;i++)
System.out.println(args);
public class Fun{
public static void main(String args[]){
//Test t=new Test("Hello","good bye");
Test.main(new String[]{"Hello","good bye"});
} Thanks,

Passing argument to function

hi to all
i have one querry
i want to pass an argument to function through jsf tags
can you help me out
how i will do it

i want to pass two argument to "populateSubStationsName()" method
is it possible
i heard about the tag name "attribute" is it possible to pass through this tag

Yes, it is. See [1]. But I doubt if you actually need this. Reading the articles at [2] and [3] may give new insights.

Pass arguments to javascript from plug in...

Hi,
I m using InDesign CS3 on MAC OS...
I have a plugin calling a javascript. I need to pass a string value from the plug in to the script...
I found that there is a parameter in the method RunFile in IScriptRunner.h for this purpose... But i don kno how to use this...
virtual ErrorCode RunFile(const IDFile& idFile, IScriptEventData* data, bool16 showErrorAlert = kTrue, bool16 invokeDebugger = kFalse) = 0;
where,
@param data is used to pass arguments and return the result IN/OUT
What does this IScriptEventData* data carry???
How to pass a string value as argument to javascript from plugin code and how to retrieve and use it there...
Is there any sample code for this?
Someone pls guide me...
Thank you.

Are there other command line options with extendscript, like compile to jsxbin etc.. Where is this documented?

I used the below command to run script from command prompt, I'm able to run the script but not able to pass arguments to the script.
"C:\Program Files\Adobe\Adobe Utilities\ExtendScript Toolkit CS4\ExtendScript Toolkit.exe" -run "C:\Program Files\Adobe\Adobe InDesign CS4\Scripts\test.jsx"
Any suggestion would be helpful..
It may be possible to edit prefs file with command line and to check file in script.

How can we pass argument to static block of code????

hi ,
My question is we can use static initialization block for having functionality like constructors for initializing static variable ,but we cannot pass arguments to static initialization block then how can I create functionality like parametrized constructors.Whats the alternative shall I use a static method to perform this functionality,since all methods in given class are static and
there is no need of creating instance of class.

jduprez wrote:
Hello Jussi,Salut Jérôme
That's probably a more maintenable design.
However what do you base your remark on - I'm struck by the word obviously?
Is there some design principle from which this advice so naturally ensues that it is obvious ?Yes I read my posting later on and thought about changing it, since it's not necessarily an obvious solution. I was making assumptions that I didn't clarify from the OP.
In the OP's case, the "state" on which those methods operate is apparently fixed, presumably at the beginning of the program, so what's wrong with all this staticness?
I can list:
- threading issues (a non-issue after some initialization phase), that you wouldn't have with immutable instances
- harder unit-testing (that's not an OO design problem, more a methodology problem)
- mix and confusion between static and non-static state if the class ever happens to have both, in future maintenance. All good points, I see all-static classes as a "code smell" and especially in this case when there's parametrization involved.
Now we just need to have the OP explain his situation a bit better.

Passing arguments

Our teacher just taught us about methods and passing arguments, etc. I have been over our text book and I don't quite understand how it works. Any help?
PROBLEM:
?     Write a program with four methods. One is the main method. The other three are named startMessage, message, and finishMessage.
?     Within the startMessage method, place code to print out the message ?The program has started.?
?     Within the message method, place code to print out any message that is passed, as a String, into the method using a String parameter named output.
?     Within the finishMessage method, place code to print out the message ?The program is done.?
?     When the program begins call the startMessage method.
?     Then display the following dialog box:
"Enter a message:"
?     Using a While loop, respond to the user?s input appropriately:
     If the user presses OK display whatever the user has entered by calling the message method with the user?s input as the argument. Continue to display the dialog box and display the user?s input until they press Cancel.
     When the user presses Cancel stop showing the dialog box, and do not display what the user has entered.
?     After the user presses Cancel, and before the program terminates, call the finishMessage method.
?     Terminate the program.
here is what I have so far:
public static void main(String[] args) {
          startMessage();
          String userMessage = JOptionPane.showInputDialog("Enter a message:");
          while (userMessage != null){
               message(userMessage);
               JOptionPane.showMessageDialog(null, "Here is message" + message());
               userMessage = JOptionPane.showInputDialog("Enter a message:");
          finishMessage();
          System.exit(0);
     public static void startMessage(){
          JOptionPane.showMessageDialog(null, "The program has started.");
     public static String message (String output){
          output = userMessage;
          return(output);
     public static void finishMessage(){
          JOptionPane.showMessageDialog(null, "The program is done.");
}what's giving me the problem is the message method; I can't figure out how to pass whatever they put in the userMessage variable to the message method

I am stuck here
PROBLEM:
?     Change your C6E2 class by adding a new method called getNumberInput. This method will be used to get a number input from the user, replacing the lines of code in the main method that were previously used. You will need to call this method twice from the main method, prompting for the first and second numbers in turn.
?     Write the method so that the prompt displayed in the input dialog box is passed through an argument.
?     The return type of this new method will be a double.
I can't figure out how to pass the input paramater correctly, any help?
public static void main(String[] args) {
          double num1 = 0;
          double num2 = 0;
          double addResult = 0;
          double subtractResult = 0;
          double multiplyResult = 0;
          double divideResult = 0;
          double input1 = getNumberInput(num1);//this is where I am stuck
          double input2 = getNumberInput(num2);
          addResult = add(num1, num2);
          subtractResult = subtract(num1, num2);
          multiplyResult = multiply(num1, num2);
          divideResult = divide(num1, num2);
          JOptionPane.showMessageDialog(null, addResult);
          JOptionPane.showMessageDialog(null, subtractResult);
          JOptionPane.showMessageDialog(null, multiplyResult);
          JOptionPane.showMessageDialog(null, divideResult);
          System.exit(0);
     }//main
     public static double getNumberInput (double input){
          double output = 0;
          Double.parseDouble(JOptionPane.showInputDialog("Enter a number:"));
          return output;
     public static double add (double term1, double term2){
          double result = term1 + term2;
          return result;
     }//add
     public static double subtract (double term1, double term2){

Passing arguments in Visitor Pattern

Does anybody have a nice solution to passing arguments in Visitor pattern?
The Visitor pattern is used to process an object structure (such as an abstract syntax tree) in many different ways without cluttering definitions of the objects with methods needed for all different kinds of processing. Instead, each object has only one method, "void accept(Visitor v)". The method calls back a method in the Visitor that is appropriate for the object. Different kinds of processing use different Visitors, each with its own set of object-processing methods.
My problem is that I need to pass arguments or receive results from the object-processing methods, different for different kinds of processing.
One solution is to have many "accept" methods with different signatures. This beats the idea that we do not need to modify definitions of the objects if we want to introduce new kind of processing.
Another is to provide "accept" with an Object result and a sufficient number of Object arguments, to be used as necessary by different Visitors. It results in clumsy and unreadable code. Detestable.
Alternatively, one could provide fields in the objects to pass the information when needed. This frees the invocations of "accept" from dummy arguments/results, but does not seem nice.
One can also forget all about Visitor pattern, and let the processing method test the object class using "instanceof" and call the right method. But this is a pure blasphemy against everything called OO.
Is there any better way that I am too blind to see?

Sounds to me like you've got a case of combining different concerns into the same design. I think you're looking at multiple problems, all of which require you to process an object structure.
I'd make a general framework for processing my structure, and then use a specific interface for each problem. I would avoid re-using the Visitor pattern for multiple concerns as it leads to exactly the problems you're facing.
If you're dead-set on using the Visitor; how about having a mediator or adapter between the visited class and the Visitor that deals with the specifics of each invocation?
Personally, I think the Visitor pattern violates basic encapsulation and polymorphism - but that's just my opinion. I try to avoid using it unless I'm stuck with NO other solution.
Good luck.

Passing Arguments to MIDlets

Is there a means for passing arguments to MIDlets when they are launched? Here's my situation. I'm using a Palm VII with Palm OS3.5. It does not support MIDlet http connections using the onboard wireless antenna. A workaround is to create a pqa for the web stuff, and launch the midlet from within the pqa to do the on-board stuff, like persistant storage. Problem is this is no use unless there is a way to pass arguments similar to to passing command line arguments in J2SE. Anyone have any ideas?

There is a way to work which is similar to command line arguments as in J2SE in J2ME. There is a method in MIDlet class getAppProperty(String key). This method tries to get the value from jar or jad file using the key. In the jad file you can keep an attrribute like "myatt1" whose value can be set to "testing".
i.e., myatt1: testing
Then if you use getAppProperty("myatt1"), it will return you a string which is nothing but "testing".
Have a good day.

Passing arguments to the jsx file from command line

Thanks for taking my question.
I am using the following to be able to run my script from the command line.In case you were wondering on why i would be doing this- i would need to invoke the javascript from a server side code(like java,php etc. in my case it is java)
"c:\Program Files\Adobe\Adobe Utilities\ExtendScript Toolkit\ExtendScript Toolkit.exe" "c:\path to script\myscript.jsx"
Anyways, i have been successful in running the myscript.jsx from the command line but i am not able to figure out how i could pass arguments to "myscript.jsx" from the command line, and be able to refer to these arguments within the script.
I have tried the following
"c:\Program Files\Adobe\Adobe Utilities\ExtendScript Toolkit\ExtendScript Toolkit.exe" "c:\path to script\myscript.jsx" "argument1" "argument2"
and tried to refer these arguments within the script using arguments[0] and arguments[1] . But looks like this does not work.
Any thoughts?????

To run JavaScript from the prompt using ExtendScript Toolkit 1.0.3 or 2.0.2 you need to do the following:
Add the line #target indesign to the top of your script otherwise ESTK will open without executing the script. Example:
#target indesign
//MakeDocumentWithParameters.jsx
//An InDesign CS2 JavaScript
//Shows how to use the parameters of the document.open method.
//The first parameter (showingWindow) controls the visibility of the
//document. Hidden documents are not minimized, and will not appear until
//you add a new window to the document. The second parameter (documentPreset)
//specifies the document preset to use. The following line assumes that
//you have a document preset named "Flyer" on your system.
var myDocument = app.documents.add(true, app.documentPresets.item("Flyer"));
//SaveDocumentAs.jsx
//An InDesign CS2 JavaScript
//If the active document has not been saved (ever), save it.
if(app.activeDocument.saved == false){
//If you do not provide a file name, InDesign will display the Save dialog box.
app.activeDocument.save(new File("/c/temp/myTestDocument.indd"));
Ensure Indesign is open. Execute the following command:
"C:\Program Files\Adobe\Adobe Utilities\ExtendScript Toolkit\ExtendScript Toolkit.exe" -run "[path to script]\script.jsx"
For example:
"C:\Program Files\Adobe\Adobe Utilities\ExtendScript Toolkit\ExtendScript Toolkit.exe" -run "C:\Program Files\Adobe\Adobe InDesign CS2\Presets\Scripts\test.jsx"
This command can be easily called from Java or any other third party application of your choice.
It took me a while to find this information, so I thought I'd share it with everyone.
Good luck!
