In Groovy, you can get the end_time and its value by using the System.currentTimeMillis() method. This method returns the current time in milliseconds since the epoch (January 1, 1970). You can store this value in a variable and use it as the end_time in your script. Here is an example of how you can get the end_time and its value in Groovy:
1 2 |
def end_time = System.currentTimeMillis() println "End time: ${end_time}" |
This will print out the current time in milliseconds as the end_time. You can then use this value in your Groovy script for various purposes such as calculating the duration of a process or setting a timeout.

How to define a list in Groovy?
In Groovy, a list can be defined using square brackets and separating elements with commas. Here is an example of defining a list in Groovy:
1
|
def myList = [1, 2, 3, 4, 5]
|
This creates a list called myList containing the elements 1, 2, 3, 4, and 5. You can access elements in the list using their index, starting from 0, like this:
1 2 |
def firstElement = myList[0] // Accessing the first element in the list println(firstElement) // Output: 1 |
You can also define a list of strings in Groovy:
1
|
def stringList = ["apple", "banana", "cherry"]
|
Lists in Groovy are similar to arrays in other programming languages and can be used to store multiple elements of any type.
How to print output to the console in Groovy?
In Groovy, you can print output to the console using the println() function. Here's an example:
1 2 |
def message = "Hello, World!" println(message) |
This will print "Hello, World!" to the console.
What is the Grails framework and how does it relate to Groovy?
Grails is a web application framework built on top of the Groovy programming language. It provides a high-productivity environment for building web applications by leveraging the power of Groovy and other well-known technologies such as Spring and Hibernate.
Grails simplifies the process of building web applications by providing a convention-over-configuration approach, which means developers do not need to spend time on boilerplate code and can instead focus on building features.
Groovy is the main programming language used in Grails, as it provides a more concise and expressive syntax compared to Java. Grails takes advantage of Groovy's dynamic nature and metaprogramming capabilities to enhance developer productivity.
In essence, Grails and Groovy work hand in hand to provide a powerful and efficient platform for building web applications rapidly. Developers can leverage the benefits of both technologies to create scalable, maintainable, and feature-rich web applications.
