How do you use regular expressions in Cucumber?

We can use regular expressions in Cucumber for selecting a collection of similar statements in the feature file.

Example

feature file

Feature: Exam Syllabus
Scenario Outline: Summer and Winter Exam Schedule
Given Exam time table in summer season
Given Mathematics and Physics Syllabus
Given Exam time table in winter season

The step Definition file has @Given("^Exam time table in ([^\"]*) season$") which maps two Given statements in a Feature file with the help of regular expression.

Example

@Given ("^Exam time table in ([^\"]*) season$")
public void timeTable(String season){
   if (season.equals("winter")){
      System.out.println("The winter syllabus");
   }else{
      System.out.println("The summer syllabus");
   }
}
@Given ("^Mathematics and Physics Syllabus$")
public void syllabusList(){
   System.out.println("Mathematics and Physics syllabus is");
}
