Make components like JPanel / Containers .. from a String..

public class PuzzlePieces {
     private String area;
     private String *container* = area +"Container";
     private String panel = area +"Panel";
     private Container *container* = new Container();
     private int number;
     public PuzzlePieces(String area, int numbersOfPices) {
          this.area = area;
          this.number = numbersOfPices;
     }as you can see I want to make a Container out of a Sting. How can I do this? Please make an example if you have a solution. TY

I get a string in, as you can see. I want to make/add JButton, JPanel, Containers .. based on name of the String I get in.
String
StringPanel
StringContainer
But I cant write like this
Container String +"Container" = new Container();What's the best way to solve this..You want the variable names for those Containers to be based off the Strings? Is that what you mean? Why do you want/need to do that?
The go-to solution for stuff like this is to use a Map of String, Container pairs. But why over complicate your program with stuff you probably don't really need?

Make Array of int's from a String

Hi,
Trying to transform a String into an array of ints. The following works, but seems a little longwinded for what must be quite a common function - specifically line 9 in the code (turning a char into an int). Can anyone suggest an easier way?
public class IntArray {
    public static void main( String[] args ) {
        if ( args.length == 1 ) {
            String s = args[ 0 ] ;
            int sLength = s.length() ;
            int[] argIntArray = new int[ sLength ] ;
            for ( int j = 0 ; j < s.length() ; j++ ) {
                // This line ...
                argIntArray [ j ] = Integer.parseInt( s.charAt( j ) + "" );
            for ( int j = 0 ; j < argIntArray.length ; j++ ) {
                System.out.println( argIntArray[ j ] );
        } else {
            System.out.print( "Please enter an int" );
}Thanks,
Rich

I'm not sure how common it is, but since you are assuming that the input is a String that represents an int...
public class IntArray {
     public static void main( String[] args ) {
          if ( args.length == 1 ) {
               String s = args[ 0 ] ;
               int sLength = s.length() ;
               int[] argIntArray = new int[ sLength ] ;
               for ( int j = 0 ; j < s.length() ; j++ ) {
                    // This line ...
                    argIntArray [ j ] = s.charAt( j ) - '0' ;
                    //I suggest checking for <0 or >9
               for ( int j = 0 ; j < argIntArray.length ; j++ ) {
                    System.out.println( argIntArray[ j ] );
          } else {
               System.out.print( "Please enter an int" );

How do I make a Datagram Packet from a String?

I am looking to make a Datagram Packet from a string. If I send a command to a server that allows remote connections via UDP, such as "restart" it will restart the server. I can accomplish this easily through the fput() method of PHP.
I want a Java version of my utility, and am using the DatagramSocket and DatagramPacket classes. I see that I need to make a byte array and put it inside a DatagramPacket. How would I go about putting the string "restart" into a byte array?
Thanks,

Use the following code to send a Datagram:-
import java.io.*;
import java.net.*;
// This class sends the specified text as a datagram to port 6010 of the
// specified host.
public class UDPSend {
    static final int port = 6010;
    public static void main(String args[]) throws Exception {
        if (args.length != 2) {
            System.out.println("Usage: java UDPSend <hostname> <message>");
            System.exit(0);
        // Get the internet address of the specified host
        InetAddress address = InetAddress.getByName(args[0]);
        // Convert the message to an array of bytes
        int msglen = args[1].length();
        byte[] message = new byte[msglen];
        args[1].getBytes(0, msglen, message, 0);
        // Initilize the packet with data and address
        DatagramPacket packet = new DatagramPacket(message, msglen,
                               address, port);
        // Create a socket, and send the packet through it.
        DatagramSocket socket = new DatagramSocket();
        socket.send(packet);
}This uses argments, if you want a string change the code accordingly.

Is there an easy way to convert from a String with a comma, ie. 1,000.00 to a float or a double?
thanks,
dosteov

Like DrClap said: DecimalFormat. However, make sure you understand the Locale things, as explained at http://java.sun.com/j2se/1.3/docs/api/java/text/DecimalFormat.html (which refers to NumberFormat as well) and use them explicitly. Like
public class FormatTest
public static void main(String args[])
    try
      // see NumberFormat.getInstance()
      DecimalFormat fmt = new DecimalFormat();
      Number num = fmt.parse("1,000.01");
      System.out.println(num.doubleValue());
    catch(ParseException pe)
      System.out.println(pe);
}most likely seems OK on your system, but may print "1.0" (or even fail) on some non-English platforms!

Sticking components in JPanel to GridLayout

Could please anyone help in the following.
I have an application where some JPanel with several Swing components
positioned with help of GridLayout. What I need is to
remove and place components during runtime,
but the problem is that when I remove component placed somewhere
inbetween with use of the method remove() of the class JPanel,
all components are shifted so that the empty space is filled and
even one can see that the initial GridLayout is destroyed.
How can I stick all components to the initial grid cells of GridLayout?
I mean I do not want components to shift anywhere from their original
cells.
Thank you in advance.

Well, that solution is what I came to also.
I mean I replacing removed compenent with some other invisible component.
But is this indeed the only way?
I tryied the method removeLayoutComponent() in the class GridLayout, but
I have not understood how it works and what it is for.
When I tryied it instead of remove() (of JPanel) it did not remove anything,
but it looks like something relevant to my situation.
PS The second line of my orginal poster should be read
"I have an application where some JPanel is created with several Swing components
positioned with help of GridLayout in it".
Sorry...

How to make a call to service from site studio templates?

Hi,
May be this is very basic but I am not able to figure out how to make a call to a service from site studio templates (hcsp). I have seen one example of service call in the dynamic list fragment. It makes a call to SS_GET_SEARCH_RESULTS service using executeService() method. But it doesn't take any parameters and also not very how returned results are captured.
I want to execute WCM_PLACEHOLDER service. It takes 2 main parameters dataFileDocName and templateDocName. The returned result is typically a html response.
The service typically is executed using http request and the url would be something like this
http://hd-pratapm/ucm/idcplg?IdcService=WCM_PLACEHOLDER&dataFileDocName=VIRTUSAINC&templateDocName=DETAILS_REGION_TEMPLATE
I think SS_GET_SEARCH_RESULTS service works in the similar fashion. I want to execute WCM_PLACEHOLDER service too using executeService() method. How to work with this? How can we pass parameters and capture returned results?
Regards,
Pratap

Hey Pratap,
If you are on a standard Site Studio template (page or subtemplate) you should be able to call the wcmPlaceholder idoc function directly. In fact calling the idoc function provides a lot more functionality then the service call (they locked down a few things in the service call since it is designed to be called from an external application).
The idoc call would look something like:  (taken from page 208 in this doc: http://download.oracle.com/docs/cd/E10316_01/SiteStudio/10gr4/Pdf/Site_Studio_10gR4_Designer_Guide.pdf)
As a general note when you are in idoc script and want to execute a service you call <$executeService()$> as you saw in the dynamic list. The parameters that the service runs on are in the data binder of the current request. To set parameters for an execute service you simply set idoc variables on the page before it. Example:


As for the response when you execute an idoc function, like wcmPlaceholder, that returns a String the response is immediately output to the page in the location you called the function. This would be similar in concept to a jsp scriptlet that outputs a string <%=myResponseString%>

Remove leading zeros from a string

Hi,
I have a string with some numeric value.
e.g.
String a = 54890001
I want to make it 10 digits long by padding zeros at the begining
Now a = 0054890001 ( this is for display purpose ) I know how to do it.
Now How can strip these leading zeros from this number to get back the actual number. The user sees this 10 digit number and he can change it to something like 0067490001. Now I want to strip these leading zeros.
and i shd get 67490001.
In other words, how to strip leading zeros from a string ?
Thanks for help
Vinod

I would try two things: First, just try a straightforward parsing of your String using the Integer.parseInt() method. This is only my first suggestion because the number could be interpreted as octals; only testing will really tell. Second, try a method like this:
public static String removeLeadingZeros(String str) {
    if (str == null) {
        return null;
    char[] chars = str.toCharArray();
    int index = 0;
    for (; index < str.length; index++) {
        if (chars[index] != '0') {
            break;
    return (index == 0) ? str : str.substring(index);

Generate sound(voice) from a String

Hello everybody.
I would like to generate sound from a String at Symbian devices automaticaly. I wil receive the value of this String remotely and then it will be generated to a sound.
The String will not be very long (3 to 4 words).
For example,
String test="Hello everybody";Is it possible via J2ME API?
Or do I need any external library?
Regards,
kalgik

You can't easily do it... you can using reflection:
MyStaticClass.class.getField().getXXX("MyVariable") //depending on what type the field is...But this seems like it may be a flawed design. Maybe you should try making a static HashMap in the class, use a Static init block and static get/set methods:
public class StaticClass
    static Map properties;
    static
        properties = new HashMap();
        properties.put("MyVariable", "Some Value");
        properties.put("OtherVariable", new Integer(3));
    public static Object get(String property)
        return properties.get(property);
    public static void set(String property, Object value)
        //Maybe some code checking to make sure object is right type
        //or don't use a set method at all to make the properties immutable
        properties.put(property, value);
}

Take and delete a String from another String

I have original input string= 111100001111
I need to Take for example the least 4 bits .... Output= 1111
and to be removed from the original input string so the original input string= 11110000
I am trying to make a generic one but the point is that I can not delete subset that I take from the original input String.
How can I take and delete from a string in the same time?

Possible to create an object from a String?

Hi,
is is somehow at all possible to create an object from a String ?
If we have etc.
String txt = "Carrot()";
Is it then possible to somehow cast that String and interpret it as a class type that it should make an object of ?
Like
new txt; - would then give me the same as new Carrot(); ?
Hope you understand what i mean.

How to make something like this in Edge Animate?

Hi,
I'm hoping to make something like this – https://www.youtube.com/watch?v=OJeDppEHI1g – in Edge Animate but I'm not sure where to start.
I'm new to Edge but am keen to explore.
Anyone have any feedback on whether:
1. It's possible, and
2. What techniques/effects have been used.
Thanks!

Hi there and welcome,
Could you be a little more specific on what it is exactly that you would want to create? Most of what I can see from that website is doable in Edge Animate, but if you specify what it is you'd like to accomplish I could walk you through how to do it.
Thanks!
