Evaluate String Expression

Hi all,
I am trying to evaluate a string expression against rows of data. If the data satisfys that condition/expression then its selected otherwirse its not.
To re-iterate how to evaluate a string expression like: "value < 1"
against data values like: 0, 1, 2 ...n
Any help will be appreciated. Thanks in advance.
Here's the code I am using:
      * Evaluates the Expression Either return True or False
      * @return
public boolean evalExpression() {
          boolean retval = true;
          // Identify the conditional process step
          if (this.isConditional()) {
               // get the inputs
               for (int i = 0; i < myInputs.size(); i++) {
                    ContainerDataElement containerDataElement = (ContainerDataElement) myInputs
                              .elementAt(i);
                    String data = containerDataElement.getValueAsString();
                                        // Get the conditions
                    for (int j = 0; j < myProcessConditions.size(); j++) {
                         ProcessCondition pc = (ProcessCondition) myProcessConditions
                                   .elementAt(j);
                              Boolean condition = new Boolean(pc.getExpression());
                                                  // Evaluate the expression against the data elements
                         if (condition.booleanValue()) {
                              retval = true;
                         else {
                              retval = false;
          return retval;
     }

ProcessCondion holds the Expression but I need to match the value the expression matches.
A bit like equals example I am trying out now:
public boolean evalExpression() {
          boolean retval = true;
          // Identify the conditional process step
          if (this.isConditional()) {
               // get the inputs
               for (int i = 0; i < myInputs.size(); i++) {
                    ContainerDataElement containerDataElement = (ContainerDataElement) myInputs
                              .elementAt(i);
                    String data = containerDataElement.getValueAsString();
                    com.aim.common.DebugLog.debug("dataELEMENTS--------"
                              + data.toString());
                    // Get the conditions
                    for (int j = 0; j < myProcessConditions.size(); j++) {
                         ProcessCondition pc = (ProcessCondition) myProcessConditions
                                   .elementAt(j);
                         com.aim.common.DebugLog.debug("ProcessCondition--------"
                                   + pc.toString());
                         Boolean condition = new Boolean(pc.getExpression());
                         com.aim.common.DebugLog.debug("condition--------"
                                   + condition.toString());
                         // Evaluate the expression against the data elements
                         if (containerDataElement.equals(condition)) {
                              com.aim.common.DebugLog.debug("conditionEVALUATED--------"
                                        + retval);
                              retval = true;
                         else {
                              retval = false;
          return retval;
     }

Evaluate math expression

Hi Guys,
I need to write java command line program to evaluate a mathematical
expression input by user without parantheses using Stack approach.
Can anyone give me the clue how to start of with.
Is it possible to evaluate the expression in infix notation directly using stack, without converting to prefix notation.
Thanks in advance

Is there something nicer?You can also use java 6 and javascripts. I saw a
thread where someone posted an example.
KajI posted something a couple of weeks back (reply #2):
http://forum.java.sun.com/thread.jspa?threadID=5137192
Of course, you don't need to bind any variables and can do it like this:import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;
public class ScriptDemo {
    public static void main(String[] args) {
        ScriptEngineManager manager = new ScriptEngineManager();
        ScriptEngine engine = manager.getEngineByName("js");
        try {
            String expression = "3+4";
            Object result = engine.eval(expression);
            System.out.println(expression+" = "+result);
        } catch(ScriptException se) {
            se.printStackTrace();
    output: 3+4 = 7.0

If its inside expressions then you need to escape \ as \\

Flex evaluate string for dynamic datagrid headerText

Hello: I m new to Flex and am creating headerText for a datagrid (dgTop250). How do I get the variable headerStr to evaluate correctly in the last line of the function? With the code below I get the entire string as the column header in the datagrid, not the evaluated expression that I need. Variable headerStr is evaluating correctly, I just need it to get evaluated in the headerText statement.. I know the eval function isn't available in AS3.
public function get250(event:ResultEvent):void {
(var i:int = 0; i <= dgTop250.columnCount; i++) {
    var colName:String=dgTop250.columns[i].dataField;
    var headerStr:String="top250.lastResult.IMS001HQ2.SGM.getItemAt(i)."+colName+".label";
    (dgTop250.columns[i] as DataGridColumn).headerText = headerStr;
As an example, this is what I'm getting as the header: top250.lastResult.IMS001HQ2.SGM.getItemAt(i).STOCK.label
This is what I need: Stock Number
"Stock Number" is the label for STOCK.
thanks

I would think you need to remove the quotes to get it evaluated properly
Change this ..
var headerStr:String="top250.lastResult.IMS001HQ2.SGM.getItemAt(i)."+colName+".label";
to
var headerStr:String=top250.lastResult.IMS001HQ2.SGM.getItemAt(i).[colName].label;
maybe ???

Evaluating a string expression.

hi,
If have a string,which is an expression. how can i evaluate in java.
for example
" Monday in (Monday,Sunday,Tuesday) *And* 25 > 20 *OR* 9:00 between 8:00 and 10:00"
Is there any api to evaluate the above the expression to give a Boolean value

no. you have to:
1/ create an interface "Criteria" with a single method "boolean parse();" defined in it
2/ for each kind of expression, create a class implementing criteria, with a string as parameter in the constructor, and implements the parse() method so as it will be able to return "true" when the result of the expression is true, and false otherwise
3/ when 1/ and 2/ are done, you can easily parse the complete expression (expr1 AND expr2 OR expr3) by splitting the complete expression on "AND" and "OR" statement, check what kind of criteria is expr1, expr2, and expr3, create the criteria by passing the expression as a parameter in the constructor of the appropriate class, call parse
4/ make the sum of every parse() result
if you're a java beginner, i suggest that you come back to this exercise later ; it won't be easy

Evaluate Regular expression complexity

Hi all
I've a problem on regular expression usage in my application.
I'm using a regular expression to identify objects and fetch them to be served depending on an input string with has to be matched.
each object has a property representing a regular expression to be matched to be candidate for fetching.
my program receive an external input string, then loops on the full objects collection identifying which are the object whose regular expression match the input stream.
doing an example:
obj1) key = "J*SDK"
obj2) key = "Ja*6*"
obj3) key = "JEE*"
if the input string is "Java 6.0 SDK" obj1 and obj2 are cadidate, while obj3 is discarded.
up to now everithing is fine, now here is my question:
i want only one object as output and I want the one best matching my input string.
this means that
-> obj1 is matching 4 chatacter ans has only one wildchar
-> obj2 is matching 3 characters and has two wildcard
so obj2 is discarded since it's regular expression is more complex than the obj1 one
my problem is HOW to evaulate correctly such complexity for each candidate object to be able to choose my best object.
is there some formal rule / api for this?
I'd like to match all wildcards into the regex, but doing this "by hand" would surely result in some bug due to some missing case, so a "third party" API or a grammar rule would be useful.
hoping for you help.
regards
Michele Sacchetti

ok, after days and days of research i came up to this solution:
1) I used this (http://www.brics.dk/automaton) package for regular expression which let me access the internal state automa data
2) use the getShortestExample() method to retrieve the shortest string matching the given regExp
3) evaluate the Levenshtein Distance between the given string and the one to be matched
PROs:
1) the regexp logic is fully handled by the same state machine which take cares of pattern matching in the first phase
2) the library provide me a non-regexp string to be used with comparison (e.g Levenshtein Distance evaluation)
CONs:
1) the methods getShortestExample is unaware of string to be matched, so if i use "aab|aaa" to match "aab" the method gets the first shortest sort alfabetically, that is "aaa", so I get a LD of 1 even if it should be 0, but it's quite a good deal for my application.
@endasil : your solution rely on grouping, and is based on a pre-parsing done manually so it basically went back to the "manual" parsing i wanted to avoid
Another way I'd like to give a try but had to give up was to use ANTLR (www.antlr.org) to create a parser for regular expression and then evaluating the resulting "tree size" of the parser, but wasn't able to find a formal description of RegExp grammar on the net.
do you have any suggestion or comment on my solution (or other to give a try? )

Thread to evaluate arithmetic expressions

I'm trying to write a program that evalutaes arithmetic expression concurrently using Java concurency primitives. The idea behind the threading is to avoid multiple evaluations of common subexpression. I have attached the code that I have written so far but was hoping someone could offer me a hand with the evaluate() and run() methods contained at the end of the program. Thanks.
public class Example {
     public static void main(String[] args) {
          BinaryOp plus = new BinaryOp() {
               public int apply(int n1, int n2) {
                    return n1 + n2;
          BinaryOp times = new BinaryOp() {
               public int apply(int n1, int n2) {
                    return n1 * n2;
          Arith e1 = new Operator(plus, new Number(4), new Number(5));
          Arith e2 = new Operator(plus,new Operator(times, new Number(3), e1),
               new Operator(plus, e1, new Number(6)));
          Arith e3 = new Operator(times, e2, e2);
          System.out.println(e3.evaluate());
interface BinaryOp {
     // An operator that can be applied to two numbers
     int apply(int n1, int n2);
interface Arith {
     // An arithmetic expression that can be evaluated.
     int evaluate();
class Number implements Arith {
     private int n;
     Number(int n) {
          this.n = n;
     public int evaluate() { // A number evaluates to itself.
          return n;
class Operator implements Arith, Runnable {
     private BinaryOp op;
     private Arith e1;
     private Arith e2;
     private boolean done = false;
     private int result = 0; // holds the result of previous evaluation
     Operator(BinaryOp op, Arith e1, Arith e2) {
          this.op = op;
          this.e1 = e1;
          this.e2 = e2;
          (new Thread(this)).start();
     public int evaluate() {
     public void run() {
}

I'm trying to write a program that evalutaes arithmetic expression
concurrently using Java concurency primitives. The idea behind the
threading is to avoid multiple evaluations of common subexpression. Interesting ... the main problem however is to find those common
subexpressions. Most of the evaluation of those common subexpressions
can be done in the parse/compile phase though, effectively elliminating
the need for threads, e.g. (foo+bar)-(foo+bar) can be deduced to be
equal to zero if both 'foo' and 'bar' happen to referential transparent,
i.e. they don't have side effects.
What you're doing now is just starting a new thread for every binary operator.
This is, most likely, not what you want. The strategy of what thread to
start for which subexpression must have layed out the sequence of
threads to start before actual evaluation is started (also see above).
kind regards,
Jos

How does one evaluate an expression stored as a VARCHAR 2 in a table?

I am attempting to write a single SQL statement that will select three columns of data from a table and based on the value of a string in one column perform a calculation using the other two columns. Here is an example. TableX contains three columns. For simplicity sake let's say Col1 and Col2 are Number(5) and Col3 is a VARCHAR2(25).
TableX
Col1 Col2 Col3
5 7 Col1+Col2
10 3 Col1*Col2
20 5 Col1/Col2
I would like to write an SQL statement like 'select Col1, Col2, evaluate(Col3) as "Eval" from TableX' and get the following result set back.
Col1 Col2 Eval
5 7 12
10 3 30
20 5 4
Is there an Oracle provided function like the hypothetical evaluate() provided above that will do this?
One potential solution would be to write a stored procedure that accepts the three columns as parameters and then performs an execute immediate and returns the result. However, I would like a more dynamic utility so I don't have to be resticted to a preset number of columns (3 in this example).
Any ideas would be greatly appreciated.
Thanks,
Matt

Matthew:
There is no evaluate function in Oracle, and as far as I know, there is no way to do what you want solely in sql. However, this function should do the trick.

can anyone help me plz

Hi Katherine,
Thanks for your reply;
Here is my Control flow which gives you some idea what I'm trying to do:
I'm using a for each loop container and inside it I have a Execute SQL task which generate the XMLA script (which I have passed it in a variable for which I used the connection type as ADO.net ); later I have written a script to check wheather it is returning
the correct xmla script or not and than processing the dimension.
Everything works good until the Script task and when it comes to the Process ADD it fails.
EXECUTE SQL TASK (Get XMLA Query processADD) variable value:

Tomcat 6 failing to evaluate EL expressions, Tomcat 6 bug?!!!!

Can someone please tell me this is not a bug in Tomcat 6, its too obvious and to some extend unacceptable I must be doing something wrong.
Here is my problem, I have written my own custom component to display a div tag.
the JSP is as follows:
<faces:view>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
        <title>My Custom Tags</title>
    </head>
    <body>
      <html:form>
      <h2>Cat In The Rain</h2>
      <mine:mytag title="#{index.title}">Dancing in the rain.</mine:mytag>
      </html:form>
    </body>
</html>
</faces:view>The tag class is given below:
This text #{index.title} is being interpreted as Literal text which is obviously wrong, when deployed in glassfish the code works fine.
Output text in my tomcat console is
MyTag.setProperties(): Title is literal text....
MyTag.setProperties(): title value= #{index.title}
MyTag.setProperties(): Title Value expression is null
The Tag class.
public class MyTag extends UIComponentELTag{
private ValueExpression title;
public String getComponentType() {
    return "test.MyOutput";
public String getRendererType() {
    return "test.MyRenderer";
@Override()
protected void setProperties(UIComponent component) {
    super.setProperties(component);
    if (null!= title){
      if (!title.isLiteralText()){
        component.setValueExpression("component.title", title);
        System.out.println("MyTag.setProperties(): Its not literal text.");
        System.out.println("MyTag.setProperties ():              title value = "+ title.getValue(getELContext()));
      else{
        component.getAttributes().put("component.title", title.getExpressionString());
        System.out.println ("MyTag.setProperties(): Title is literal text....");
        System.out.println("MyTag.setProperties():              title value= "+ title.getExpressionString());
    System.out.println ("MyTag.setProperties(): Title Value expression is "+ component.getValueExpression("component.title"));
}The component class.
public class MyOutput extends UICommand{
public MyOutput(){
    setRendererType("test.MyRenderer");
@Override()
public String getFamily() {
    return "test.MyOutput";

Using expression trees to evaluate an expression

i have a three parameters like age, sex and location. Now, my users while registration, can specify an expression like, age > 25 and age < 30 and sex = male OR location = 'London'. Now i get an incoming request which has certain values for age, sex and location (say: age=26 sex = male location = 'London'). Then i want to get a list of all the users registered with me who satisfies the incoming criteria. Do you think an expression tree would help me in this case? can pls someone guide me?

actually i have a fixed list of operators and operands. The only variation being that users while registration might use only a subset of those operators and operands e.g. some users may just give an expression such as 'sex=male' and some other users could give an expression such as 'sex = female AND age > 21'. So when i get an incoming request saying sex = female and age = 22 then only my second kind of users would be selected and suppose if i get an incoming message like sex = male , age = 33 then my first kind of users (though no age is specified by that user while registration but still he would be selected as the expression said sex = male and that is one of the parameters of the incoming request) would be selected. Now how do i create such a solution using an expression tree, which would evaluate the incoming request and then match it with the expression specified by the various users to find the list of those users who qualify according to the incoming request parameters. any ideas??

Evaluate string while running

If I want to implement a code as following:
//String condition = input condtion represent as string (from xml. e.g. 1=1, true, false etc)
if (condition)
How do I evaluate the input string while running?

OR use a Map, where the key is the input String and the value is a Command object. You can avoid the brittle, brain-dead "if/then/else" code that way. If the inputs and commands change frequently, this would be a good way to go that satisfies the open/closed principle nicely.

Evaluate binding expressions #{...} from Bean methods?

Hello all,
is it possible to evaluate the binding expressions that are usually given in the JSP page (e.g. #{someObject.someProperty} ) from a Bean method?
I am currently searching for a more convenient way of accessing the resource bundle from a validator and could imagine an access over #{msg.someText}.

Jstl: ExpressionEvaluator.evaluate versus Expression.evaluate

Hi,
Reading the jstl API, I noticed the method ExpressionEvaluator.evaluate().
On the other hand, ExpressionEvaluator also returns an Expression, which has its own evaluation method: Expression.evaluate().
Isn't this redundant ? Which method would be used on which occasion ?
Also, I was wondering: do I understand correctly, that one could override the ExpressionEvaluator ? So if I write my own evaluator, I could make it so that "${2+2}" evaluates to, say, "5" ?
Thanks very much.
