Convert Map String, Object to Map String,String ?

How can I convert a map say;
Map<String, Object> map = new Map<Striing, Object>();
map.put("value", "hello");
to a Map<String,String>.
I want to pass the map to another method which is expecting Map<String,String>.
Thanks

Oh wait, no, we're not! We're back to my original reply:
What do you want and/or expect to happen if one of the values isn't actually a String object but something else?Nothing like a bit of confusion :). They are and always will be String objects.
So this external method, call it external1 for now returns a Map<String, Object>, I then want to pass this map to another external method external2 which takes Map <String,String> as a parameter.

  • "Property value is not valid" when PropertyGridView tries to convert a string to a custom object type.

    Hi,
    I have a problem with an PropertyGrid enum property that uses a type converter.
    In general it works, but when I double clicking or using the scoll wheel,  an error message appears:

  • How to convert a string into an objects name?

    Hi
    I have the following problem;
    I have a string
    String a = "e1"
    and a method
    call(Event e1) that calls the "Event" class with object the name of the string a.
    How can I convert the strings name into an object so as to use it in the "call" method?
    Any ideas?
    Thanks in advance

    I don't know if this helps you, but you can do things like this.
    String a = "com.example.SomeEvent";
    //Instantiate com.example.SomeEvent
    Object o = Class.forName(a).newInstance();SomeEvent must have a non-argument constructor for this to work.
    Class that will be instantiated depens on runtime value of String a, and can be different across different executions of the program.

  • How Do I Convert a String that Names an Object to a Reference to the Object

    You get many program-specific object names in the XML that is returned by describeType.  Suppose I find an object that interests me.  What is the best way to convert the String that names the object (e.g. the id of the object) to a reference variable that points to the object? 

    Sure.  I am working on a complex application that involves several ViewStacks, several Accordions, some checkboxes, some radio buttons, some text boxes.  These components are scattered about, but all are children of a base class that is successfully enumerated by
    var classInfo:XML = describeType(vwstk);
    Suppose I write a loop as follows:
     for each (var a:XML in classInfo..accessor){
    Inside that loop I have a series of tests like
    if (a.@type == "mx.controls::CheckBox"{
    Then, I iterate thru all of the children of the base class as in:
    for  
    (var u:Object in vwstk)
    {        if  
    Inside the if I persist the checked/not checked status of the checkbox.
    The tricky part is going from the string a.@name to the Object reference u.  I doubt my proposed method will work.  Do you have a better idea?

    Without knowing what version of PHP you are using and also there does not seem to be an SAP angle, have you tried var_dump() instead of echo.
    e.g. var_dump($result);

  • Converting a String to an Object

    Is there some way of converting a String (from a textfield) to an Object? What I want is something similar to the functionality offerred by a JTable. This is because I want the user to be able to input a value of any type to the textfield (e.g. String, int, boolean, etc) and get its object representation ...
    Would a simple cast do ?
    David

    dattard,
    A string is an object, when someone enters something into a JTextField, REGARDLESS of what it is (int, double, string, etc) it is stored in the string text in that text field (JTextField.getText()).
    So if someone enters in "123", its the STRING 123, not the number one hundred and twenty three... to GET the number 123, you'll need to do something like:
    int value = Integer.parseInt( myTextField.getText() );
    to have the string parsed for the value, if you want a double, same idea:
    double value = Double.parseDouble( myTextField.getText() );
    NOTE: The number wrapper classes (Integer, Double, Float, etc.) contain "parseXXXX" methods that allow you to parse a corresponding numeric value out of a String object.
    Also, when a user enters ANYTHING into a text input field of any type, its ALWAYS a String, if you want a different version of what they entered, its up to you to parse it and decide what it was.

  • Converting a string to Class object and calling its method

    Define an interface containing the method all your classes have in common, cast the Object reference returned by newInstance to that interface, then you can call that method.

  • XML document convert into String and Insert into Database

    Hello all,
         In the FIle to File Scenario  I want to send the data to the Reciever System in xml Document and convert into String and insert into Database.
      Please can you tell me exact way how to send it.
    Thanks & Regards,
    Raj

    HI,
    As per my understanding your scenario is File to file where you will get output fiel in XML format.
    Now that XMl payload need to be passed as single string in the database via XI.
    You cauld do this but you need to imply some manipulations such as
    With the help of standard API you need to concatenate the  XML tags and create the structre along with the data.
    For e.g. in your outpuf file the XML structre contain data as
    <field1>ABCD</field1>
    Then in mapping
    The source field will be mappeda s concat(<field1>) + value of  Source field "ABCD" + concat(</field1>) to the target field.
    This is the way that you could achive the requirments else there is no direct way avaialble for it.

    Again, why?One of the problems (have been dued) in my codelab asks us to write a class as follow
    Write a class definition of a class named 'Value' with the following:
    a constructor accepting a single integer paramter
    a constructor with no parameters
    a method 'setVal' that accepts a single parameter,
    a boolean method, 'wasModified' that returns true if setVal was ever called for the object.
    a method 'getVal' that returns an integer value as follows: if setVal has ever been called, it getVal returns the last value passed to setVal. Otherwise if the "single int parameter" constructor was used to create the object, getVal returns the value passed to that constructor. Otherwise getVal returns 0.
    The setVal(int y) returns nothing, so how do I know whether it has been called or not?

    User will enter the input as 10 as it needs to be converted into 10,00. Also, 1000 which has to be converted as 1.000,00

    DecimalFormat df = (DecimalFormat)nf;
    df.applyPattern(pattern);
    String output = df.format(1111111.222);
    Pattern has an influence on number of digits between separators, but you have to use ',' for grouping and '.' for decimal. Character values for separators correspond to your Locale object.

  • Converting XML String to MessageElement array

    Hi,
    I am trying to call a .NET web service from my Java client. I used WSDL2Java to generate the java classes for calling the .NET web service. The generated classes to call the service expects an array of org.apache.axis.message.MessageElement objects. I have a string representing an XML document which looks like this:
    String xmlString = "<Results><Adjustments><Adjustment><RebuildAdjustmentID>16</RebuildAdjustmentID><IsBasicAdjustment>true</IsBasicAdjustment><AdjustmentType>stone/AdjustmentType><Title>External walls</Title></Adjustment></Adjustments></Results>"

    m[0] = XMLDoc.getDocumentElement();

  • Problem in converting the String to Date with time zone GMT

    Hi,
    When I tried to convert the string 12/05/2009 to Date, the time zone is set to BST.On the other hand, for the date 12/12/2009, the time zone is set to GMT. What should I do to get the time zone as GMT all the time.?
    SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
    String dateString = "12/05/2009";
    System.out.println(myDate.toString());

    I think you are all missing the point. java.util.Date objects always alway always store the date as the number of milliseconds since 1/1/1970 UTC so the only TimeZone they have its the implicit UTC. When you use the Date.toString() method the toString() method gets the default time zone from your environment and formats the data accordingly. This means that the same Date object will, by default, produce a different result for France and Australia and the US.
    So, if you have the date "12/5/2009" as a String then to convert it to a java.util.Date you must specify what TimeZone is implied. If it is your system time zone then you can just create a SimpleDateFormat object with the correct format and then use the parse() method to create the java.util.Date object and this will automatically be converted to UTC. If the date String represents some other time zone then you must explicitly set the time zone of the SimpleDateFormat object before parsing the string.
    The same approach applies when converting a java.util.Date object to a String. If you want anything other than your system time zone then you must explicitly tell the SimpleDateFormat what time zone you want the result formatted for.

    if...
    myDataGrid[myItem].myProperty == Object(myCheckbox).label
    ... then
    I would like to loop through my Array, counting the number of items, and then use each item as a property.
    How would I convert the string (e.g. "ownsCar") into a property "myProperty" ???

    Thanks, but my problem is that I won't know what my property will be.
    E.g. they could be...
    {svnsdkvnsdklvnsdklv: 'true', seuAfnwfnw: 'true', asfwseionf: 'true', etc.................}
    and there could be lots of them.
    I need to have myObject[N], where N is a variable property for each of the items taken from a variable length array
    so...
    ownsCar is represented by myObject.[N]
    ownsHouse is represented by myObject.[N+1]
    ownsBike is represented by myObject.[N+2]
    etc
    (sorry, this is so difficult to explain when I dont know what the answer is)
