Can't convert int into String

I'm trying to code a GUI that will give an employee id, name, salary, hire date, and vac days.
public String getFieldValue(int fieldIndex) {
          switch (fieldIndex){
          case 0: return employeeID;
          case 1: return firstName;
          case 2: return lastName;
          case 3: return empIndicator;
          case 4: return salary;
          case 5: return hireDate;
          case 6: return vacDate;
          return null;
My salary and vacDate are double and int. How do I display all the fields?
Thanks

I would use enums here, not magic numbers.
Are you trying to extract the text held in JTextFields? If so, perhaps returning String is all you need. This you can parse via the wrapper classes (i.e., Integer.parseInt(...) and Double.parseDouble(...))

CS3/CS4/CS5 Win/Mac: How can I convert a Windows string to mac?

Hi
I have a Windows coded string. I like to convert this string into a Macintosh string. This means several characters are changed, e.g. ä, ö or ü.
Is there a method in the Indesign SDK?
How can I convert a windows string into a macintosh string and back?

I don't think this should work that way. If this string is in resource file, use UTF-8 encoding and make PMString do its job. use kResourceUTF8Encoded in StringTable:
resource StringTable (kSDKDefStringsResourceID + index_enUS)
        k_enUS,                                             // Locale Id

Can't convert int to int[] URGENT!

HI list!
Here is the code part I have:
/** Holds the permutated groups which are arrays of integers. */
Vector v;
if(arg.length<3) System.exit (0); //Need at least 3 arguments
elements=new int[arg.length-1]; //Create array to hold elements
/* Copy the arguments into the element array. */
for(i=0;i<arg.length-1;i++) elements=Integer.parseInt(arg[i+1]);
groupsize=Integer.parseInt(arg[0]); //Get the number in each group.
calc(groupsize,elements.length); //Find out how many permutations there are.
v=permutate(groupsize,elements); //Do the permutation
for(i=0;i<v.size();i++) { //Print out the result
elements=(int[]) v.get(i);
System.out.println("");
for(j=0;j<elements.length;j++) System.out.print(elements
[j]+" ");
System.out.println("\nTotal permutations = "+v.size());
and the error I get is:
Permutate.java:26: Incompatible type for =. Can't convert int to int[]. for(i=0;i<arg.length-1;i++) elements=Integer.parseInt(arg[i+1]);

elements=(int[]) v.get(i);
The above statement is illegal. Its not possible to
use an array type in casting at all.
Basically you are trying to do a kind of multiple
casting, which is not possible.
You might want to store vectors in vector v instead of
arrays in vector v. Its better to do this.There's nothing wrong with the line
elements = (int[]) v.get(i);
assuming the returned object from the vector is in fact an array of int. Even then, it is a runtime exception condition not a compile-time error.
Using arrays is perfectly valid where you know the size of the array at creation and do not need to resize it during use... The arrays are fast and compact. This is however not a comment on the approach taken in this case but merely an observation that arrays are not always an inferior choice to one of the collection classes.
Now put up your dukes... ;)

Can't convert int to java.lang.Integer.

Hi everyone.
I'm working on an auction site at the moment and have problems gaining a bidID number. This is part of my code and my error.
AuctionFacade aHse = (AuctionFacade) application.getAttribute("AuctionFacade");
String strTraderName = (String)session.getAttribute("traderName");
String strPassword = (String)session.getAttribute("password");
String strIDNum = request.getParameter("auctionID");
Integer intID = Integer.valueOf(strIDNum);
Integer [] bids = aHse.getAllBids(intID);
float fltYourBid = aHse.getBidPrice(bids.length);
^
Can't convert int to java.lang.Integer.
can anyone help please?

So, does "aHse.getBidPrice" expect an int or an Integer as its parameter? And does it return an int, or an Integer, or what? The answer to those questions may lead to your solution -- look at what you are actually using as the parameter, for example.

How can I convert imovie into photo's

How can I convert imovie into photo's

For iMovie 11, you will need to download a free tool called MPEG Streamclip from Squared 5. (Google it). This is a very handy tool to have if you make videos.
In iMovie, select the clip that contains the frame that you want. Right-click on the clip and select Reveal in Finder.
You should see the clip highlighted in the Finder. Drag this clip into MPEG Streamclip. Move the playhead to the frame you want. Then click FILE/EXPORT FRAME. You can choose JPEG, TIFF, or PNG.

you can only convert one object type to another. Integer is an object int isnt. You might want to convert int to Integer and then go ahead.

How can I convert output data (string?) from GPIB-read to an 1D array?

Hello all,
I am reading a displayed waveform from my Tektronix Oscilloscope (TDS3032) via the GPIB Read VI. The format of the waveform data is: positive integer data-point representation with the most significant byte transferred first (2 bytes per data point).
The output data of GPIB-Read looks like a string(?) where the integer numbers and a sign like the euro-currency sign are seperated by spaces e.g. #5200004C3 4 4 4 4 3C3C3........ (C represents the euro-currency sign).
How can I convert this waveform data into a 1D/2D array of real double floatingpoint numbers (DBL) so I can handle the waveform data for data-analysis?
It would be very nice if someone know the solution for this.
t
hanks

Hi,
First of all, I'm assuming you are using LabVIEW.
The first you need to do is parse the string returned by the instrument. In this case you need to search for the known symbols in the string (like the euro sign) and chop the string to get the numeric strings. Here are some examples on parsing from www.ni.com:
Keyword Search: parsing
Once you parse the numeric strings you can use the "String/number conversion VIs" in the String pallette.
Hope this helps.

Convert document into string with unicode

I want to convert my document into string with all <,>,& to be converted into <, >, and &. When I am doing transformation, I am getting <,> etc.
Can anybody suggest me how to do that.
regards,

I don't know of any way to tell the parser to convert is for you, you'll have to replace the characters yourself after you got the string from the parser.
