Hi Niveditha,

There are many ways to achieve this requirement. One way is to use java service. Please see below steps.

1)In the designer create a Java Service (ex: “GetCountJava” ) (rt click-> New-> Java Service)

2)Select Input/Output tab
Add following variables in the input section:
a)Insert variable of type StringList (name it as “listOfNames” )
b)Insert variable of type String (name it as “searchName” )

Add the following variable in the output section:
a)Insert a variable of type String(name it as “count” )
(Please see attached image(1.png) for your reference )

3. Now select source tab and use following code in the “GetCountJava” method
   IDataCursor pipelineCursor = pipeline.getCursor();
   String listOfNames = IDataUtil.getStringArray( pipelineCursor, “listOfNames” );
   String searchName = IDataUtil.getString( pipelineCursor, “searchName” );
   int count=0;
   for (String string : listOfNames) {
   if(searchName.equals(string)){
   count++;
   }
   }

    IDataUtil.put( pipelineCursor, "count", count );
    pipelineCursor.destroy();
   

(Please see attached image(2.png))

The above code will read list of names and a name which is used to match against the list. Whenever there is a match count variable is incremented.

4)Run the service and input list of names and name in the input section(result1.png . The output will give the count.
