Disable certain rows of data to be displayed.....

Question

I have a program in which the table will display data fed from the server .
I would have a function in which user have the freedom to select which data he wants to be display on the next refresh page.
How do i prevent the other data that user does not require to be displayed on the table ??
by the way all these will affect the rows in the table , so how do i go about manupilating the rows?
Thank YOu anyone . .

If you mean that the user will enter a kind of scan, like myitem* or item using as a wildcard, I would create a class called ScanType where you have diiferent return values. In your main code you can use if..else depending on the scantype.
public final class ScanType
     /** The types are:
     *  -1: source
     *   0: *ource
     *   1: *ourc*
     *   2: sourc*
     *   9: s*urce
     private ScanType()
          super();
     public static final int getScanType(String source)
// Default is not valid. scan type : 9
          int returnValue = 9;
// Check scan type -1: source
          if(source.indexOf("*") == -1)
               returnValue = -1;
// Check scan type 0
          else if((source.charAt(0) == '*') && (source.charAt(source.length()-1) != '*'))
               returnValue = 0;
// Check scan type 1
          else if((source.charAt(0) == '*') && (source.charAt(source.length()-1) == '*'))
               returnValue = 1;
          else if(source.charAt(source.length()-1) == '*')
               returnValue = 2;
          return returnValue;
}You can test this with this code:
public class ScanTypeTest
     public static void main(String[] args)
          String kalle = "source";
          System.out.println("Scan type: -1 " + kalle + " " + ScanType.getScanType(kalle));
          kalle = "*ource";
          System.out.println("Scan type:  0 " + kalle + " " + ScanType.getScanType(kalle));
          kalle = "*ourc*";
          System.out.println("Scan type:  1 " + kalle + " " + ScanType.getScanType(kalle));
          kalle = "sourc*";
          System.out.println("Scan type:  2 " + kalle + " " + ScanType.getScanType(kalle));
          kalle = "s*urce";
          System.out.println("Scan type:  9 " + kalle + " " + ScanType.getScanType(kalle) + " is invalid");
}The rest of the code you have to create yourself as I don't know how you will retrieve the data to be displayed.
