OSB - XQuery - Sample Switch Case

Hi,
Can some one pls give me a sample XQ, with Switch Case statement in it, which [Syntax] works in OSB.
Regards,
Kaleem...

I am really afraid that OSB 11g supports XQuery 1.0
http://download.oracle.com/docs/cd/E21764_01/doc.1111/e15867/xquery.htm
while the switch statement is introduced only in XQuery 1.1
http://www.w3.org/TR/2009/WD-xquery-11-20091215/#id-switch
for the time being, you will have to resort to a cascade of if - then - else :o(

BPEL-Instanz dies silent if switch case is true boolean

Hello,
it is very curios. I have the following switch case:
xp20:compare('string1', 'string2') = 0
or
string(xp20:compare('string1', 'string2')) = '0'
The validation is ok, and the compiler compiles with 0 errors / 0 warnings.
If I try to invoke the process, the instance dies silent.
If i write 'string1' = 'string' the behavior is as expected and the instance is running.
What's the reason
I am using the last stable release version.
Best regards
Harald

i just tested your case in 10.1.3.x, it works fine for me. i can see "'two strings do not match" in output variable as expected. can you please copy and past your entire switch block.
here is my test case ( i took the Switch.bpel sample under references directory):
<switch>
<case condition="xp20:compare('string1', 'string2') = 0">
<assign>
<copy>
<from expression="'Value is greater than zero'"/>
<to variable="output" part="payload" query="/tns:resultMsg/tns:valueResult"/>
</copy>
</assign>
</case>
<otherwise>
<assign>
<copy>
<from expression="'two strings do not match'"/>
<to variable="output" part="payload" query="/tns:resultMsg/tns:valueResult"/>
</copy>
</assign>
</otherwise>
</switch>

Troubles with a switch case and final expression?

Been developing C/C++ for quite a while and still new to Java, and struggling with even the simplest things ... Why isnt this switch/case working?
have some final "variable" declared in a class contating "constants" like this ...
public class CConstants {
public static final int MY_CONSTANT1 = 0x01;
}Now, If I'm trying to use "MY_CONSTANT1" in a case stateent, I get the error "constant expression required" ?
CConstants c = new CConstants();
switch(condition){
case c.MY_CONSTANT1: { //do some work; break; }
default: { }
}I thought this would be a nice idea to increase readability as there will be a long switch/case statement.
Please help!

You should refer to that constant as CConstants.MY_CONSTANT1.
Refering to it via a reference to CConstants is possible but strongly discouraged (infact I'd make CConstants non-instantiable by adding a private constructor).
Other than that your code should work.
Could you post a SSCCE that demonstrates your problem.

I would like to know how can i compare a switch case 1 and case 2 in C# is it possible to do that? obs i am a begginer :)

i would like to know how can i compare a switch case 1 and case 2 in C# is it possible to do that? obs i am a begginer :) I tried to do it with search and sort but it did not go well

let me give you an example if you add a word case 1( lagg ord) how can i compare that word with case 2 words ( in case 2 already exist 5 words)

Switch/Case: How to test byte values in hex format

OK, this may be a silly question, but being new to Java, I can't seem to get this to work.
I have a byte value that I want to test in a switch/case statement. The value was assigned to the byte in hexadecimal format. However, testing only works if I use the decimal value of the byte!
What's even stranger: It does work in a simple if/else statement. In my debugging attempts, I discovered this using the following code:
//*temporary debug routine
memoryCells[0] = (byte) 0x86; //LDA
if(memoryCells[0] == (byte) 0x86)
    System.err.println("byte recognized as hexadecimal!");
else
    if(memoryCells[0] == -122)
        System.err.println("byte recognized as decimal!"); So, this works in an ordinary if/else statement, but why doesn't it also work in the complex switch/case statement? Snippet below:
       switch (currentOpcode)
            case (byte) 0x86:
                //*LDA immediate (2 bytes, 2 cycles)
                registerA = b;
                currentOpcode = 0x00;
                cycleCounter = 0;
            break;
        }Thanks in advance for any suggestions...

    public static void main(String[] args) throws Exception {
     byte test = (byte)0x86;
     switch(test)
     case (byte)0x86:
              System.out.println("Success");
          break;
     default:
              System.out.println("ooops");
    }This works for me.

Problems with a result in a switch/case control statement

I am having troubles with a switch/case statement in which I am trying to get a result returned from different operators. The problem is that the result always returns 0 no matter what I put in the driver class.
The class where the result needs to be returned looks like this:
public class Calculator
     private int num1;
     private int num2;
     private char operator;
     private int result;
     public Calculator(int num1, char operator, int num2)
          this.num1 = num1;
          this.operator = operator;
          this.num2 = num2;
     } // end constructor
     public int getNum1()
          return num1;
     public char getOperator()
          return operator;
     public int getNum2()
          return num2;
     public int getResult()
          return result;
     public int calculate()
          switch(operator)
               case '+':
                    int result = num1 + num2;
                    break;
               } // end case '+'
               case '-':
                    int result = num1 - num2;
                    break;
               } // end case '-'
               case '*':
                    int result = num1 * num2;
                    break;
               } // end case '*'
               case '/':
                    int result = num1 / num2;
                    break;
               } // end case '/'
               case '%':
                    int result = num1 % num2;
                    break;
               } // end case '%'
          } // end switch
          return result;
     public String toString()
          String message = (num1) + " " + (operator)
                              + " " + (num2) + " " + "=" + " " + result + "\n";
          return message;
} // end class
The driver class looks like this:
import javax.swing.JOptionPane;
import java.lang.StringBuffer;
public class CalculatorApp
     public static void main (String[] args) // begin main
          String choice = "";
          while (!(choice.equalsIgnoreCase("x"))) // begin while loop
               String number1 = JOptionPane.showInputDialog(
                              "Enter a positive integer: ");
               String operatorInput = JOptionPane.showInputDialog(
                              "Enter operator (+, -, *, /, %): ");
               String number2 = JOptionPane.showInputDialog(
                              "Enter another positive integer: ");
               int num1;
               char operator;
               int num2;
               num1 = Integer.parseInt(number1);
               operator = operatorInput.charAt(0);
               num2 = Integer.parseInt(number2);
               Calculator calculator = new Calculator(num1, operator, num2);
               String message = calculator.toString() + "\n"
                                   + "Press Enter to conitnue or 'x' to exit.";
               choice = JOptionPane.showInputDialog(message);
          } // end while loop
          System.exit(0);
     } // end main
any help would be wonderful! I don't know why the result returned is always 0 but it is. Thanks!

The previous poster is correct. You never call the calculate method. If you don't call it, no one's going to call if for you. This stuff doesn't work by magic. I think you've misunderstood your prof's intent in this regard.
However, it still won't work with the changes previously suggested, because declaring an int result in the calculate method will hide the instance field of the same name, which is what your getResult() method retrieves. Don't delare result at all in your calculate method.
That said, it would be architecturally a lot better if the calculate method returned the result rather than storing it back into the instance.

Switch/case limit

I am encountering a very strange problem.. after 39 cases in
my switch case statement the 40th case does not get executed.. the
code is in my go button and there are like 1000+ lines of code in
there.. if I replace my 39th case with the 40th it works but it
doesn't execute anything after that!! is there a limit on the
number of case statements we can use in action script??? I am
really confused with this problem...

no, but there is a byte limit on a single code block ... I
can't remember the number off hand. So that's probably what's going
on there, you might want to consider a looping test or using an
array.

Break statement not working in switch case

Hi,
I've run into this problem multiple times and have looked up the syntax for a switch statement. The problem with the code below is that when it goes into the first case, it executes the break statement but still executes the next case instead of breaking out of the switch case. Can anyone see whats going wrong?
try
            switch (columnProps.getCellType())
                 case (ExcelConstants.CELL_TYPE_STRING):
                     excelCell.setCellValue(iterator.getCurrentColumnStringValue());
                     break;
                 case (ExcelConstants.CELL_TYPE_NUMERIC):
                     excelCell.setCellValue(iterator.getCurrentColumnIntValue());
                     break;
catch (Exception e)
System.out.println(e.toString()):


it executes the break statement but
still executes the next case instead of breaking out
of the switch case. Can anyone see whats going wrong?You can if you put in traces (print statements) in proper places. This will allow you to exactly follow the switch behaviour.

Help with Switch-Case Statement

How do you get this in a switch-case statement or work with it?
          if (age < 70) {
                    JOptionPane.showMessageDialog(null, "People that are below the 70s are nothing special.");
          else if (age > 69 && age < 80) {
                    JOptionPane.showMessageDialog(null, "People that are in their 70s are called septuagenarian.");
          else if (age > 79 && age < 90) {
                    JOptionPane.showMessageDialog(null, "People that are in their 80s are called octogenarian.");
          else if (age > 89 && age < 100) {
                    JOptionPane.showMessageDialog(null, "People that are in their 90s are called nonagenarian.");
          else (age > 99 && age < 110) {
                    JOptionPane.showMessageDialog(null, "People that are in their 100s are called centenarian.");
               }Thanks~

As per Java Specification, swtich case expects an integer and boolean cannot be used as param for switch.
In your case switch can be used like this.
int index = age /10;
switch(index) {
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
Your First case
break;
case 7:
your second case
break;
case 8:
third case
break;
case 9:
fourth case
break;
default:
fifth case
break;
Take note of the break statements. Its very important. But I wont prefer in this case. Code looks awkward and is not so meaningful.....

DoGet method is called 2 times when a switch-case statement is used

in your case you want 'count' to be a class attribute rather than a local variable. But yes, incrementing it each time that the method is called will serve your purpose.

Regular expression in a switch case

Hey guys,
I have a string "52x + 60" and i want to extract 52x and 60 using regular expressions and a switch case
Is this the right way of doing it?
var equation:String = "32x + 5"
var numberExract:RegExp = /\d+/
var xExtract:RegExp = /d+/x/
for(var i:Number=0; i<equation.length; i++)
                    switch(equation.charAt(i))
                              case numberExtract.exec(equation):
                              trace("number");
               break;
               case xExtract.exec(equation):
               trace("x");
               break;
Because it's not tracing anything when i try

Here is a quick and dirty approach - can be customized, optimized and more elegant expressions used:
// equation
var string:String = "x^2 + 5x + 5 - x7 + 8 / 4";
// value replacing xs
var value:Number = 60;
// replace xs with value
// if x comes after digit
string = string.replace(/(?<=\d)x/g, String("*" + value));
// if x comes before digit
string = string.replace(/x(?=\d)/g, String(value + "*"));
// all other xs
string = string.replace(/x/g, String(value));
// remove spaces
string = string.replace(/\s/g, "");
// get pairs with first level math
var pattern:RegExp = /(\d+[\*\^\/]\d+)|\D|\d+/g;
var result:Number = stringToMath(string.match(pattern));
trace("result", result);
function stringToMath(match:Array):Number
    // digits surrounding operator
    var pattern:RegExp = /\d+\D\d+/;
    for (var i:int = 0; i < match.length; i++)
        if (match[i].match(pattern))
            match[i] = String(calculate(match[i]));
    trace("loop result", match);
    return calculteSum(match);
* Calculates sums
* @param    array
* @return
function calculteSum(array:Array):Number
    var result:Number = array[0];
    for (var i:int = 1; i < array.length - 1; i++)
        if (array[i] == "+")
            result += array[i + 1];
        else if (array[i] == "-")
            result -= array[i + 1];
    return result;
* First level math
* @param    string
* @return
function calculate(string:String):Number
    var operator:RegExp = /[\+\*\/\^\-]/g;
    var digits:Array = string.match(/\d+/g);
    var num:Number = 0;
    if (digits && string.match(operator) && digits.length > 1)
        switch (string.match(operator)[0])
            case "*":
                num = digits[0] * digits[1];
                break;
            case "/":
                num = digits[0] / digits[1];
                break;
            case "+":
                num = digits[0] + digits[1];
                break;
            case "-":
                num = digits[0] - digits[1];
                break;
            case "^":
                num = Math.pow(digits[0], digits[1]);

Can I test (junit) default case of switch-case statement ?

Hi,
I have a class which has switch-case statements and I am trying to junit test with 100% coverage. My switch-case workes based on enum values.
say my enum values are 1, 2.
switch(getEnumValues) {
case 1:
return "some value";
case 2:
return "some value";
default:
throw new UnsupportedOperationException("No such enum value supported.");
I have test case to test the case 1 and 2 but I am not able to test default case. Can anyone please let me know how can I right a junit test case for default case.

~If I'm reading the OP correctly, they're 1 and 2, not ONE and TWO. That is, not values of a Java enum.
If this is the case, then the easiest way to test the default case is to break the swtich out into a separate, package-accessible method that takes and arg and passes that onto the switch. (There may be variations on this, depending on how your code is structured.)
However, in a similar vein to what the others are saying, if you already know that you'll only ever have 1 and 2 by the time you get to the switch (maybe because the value comes from an argument to the enclosing method, and you've already unit tested that it appropriately throws an IllegalArgumentException when other values are passed, then there's no need to test the default.
Finally, though if it is ints 1 and 2, rather than a true enum, why not switch to an enum?

How can i subtract two numeric numeric numbers from two switch cases ?

I have two switch cases in my labView program. I can see them individually on front panel but i need to subtract them and see the result on front panel.
Can someone please help me out...
I am trying to display (Result1 - Result 2) on my front panel. Result1 and Result2 will change with time.
Regards,
Awais

Move result 1 and result 2 out of the case structures and subract them.
Right now result 1 or result 2 only get written to if its respective comparison is true. What do you want to do with the math if either comparison is false? You haven't defined your problem clearly enough.

Switch case list UI

Hi!
For pedagocial and c-like reasons i'd like there to be a "Case-unbundle", which would be very nice if you're only calling sub-vi's in a case e.g.
Is there any way to create such a thing?
Instead of the Case-square i want it to be a "Unbundle by name" where i connect each output to my sub-vi's (like a multiplexer) and the appropriate one is called.
Any ideas?

Well, nice asumptions, but i have another one:
LabVIEW has a case structure where only one single case is visible at a time. This is a huge difference to C-based languages where a switch-case displayes every case at the same time in a "list".
I think the question from the OP is: "Is it possible to display a case-structure in LabVIEW 'flattened' so that every case is visible at the same time?"
And to answer this question: No it is currently not possible, was never possible and hopefully will never be. But you can create a "report" using the print-function and this can automatically create screenshots of each case and display them next to each other.....
just my 2cents
