Online Kotlin Classes, Training, or Courses: Which Is the Right Option?
Online Kotlin courses, classes, and training programs all have something unique to offer students. Ultimately, the one you choose should accommodate your budget, desired concentration, timeframe, and preferences. There are no right or wrong choices among the three options. The program you pick should be right for you.
How to Choose the Right Online Kotlin Course, Class, or Training Program
First Factor: Affordability
One of the biggest factors to consider is the cost of the program. While some programs are offered for free, others can range from hundreds to thousands of dollars. There are many excellent and reputable courses available online, so choose options within your budget.
With that, most program providers offer different forms of financial assistance, including payment plans, discounts, scholarships, and grants. So, if there’s a particular program you’re set on pursuing but it’s not within your budget, check out the provider’s website and see what financing options are available.
Second Factor: Hands-On Experience
If you’re pursuing an online Kotlin course for professional reasons, it’s really important to choose a program that includes hands-on experience. This is especially important if you’re a beginner and you want to gain entrance into the tech world.
Hands-on experience prepares you for the tasks you can expect in the workplace, and it allows you to build your professional portfolio for employment. Most courses and training programs offer hands-on training, including entire projects.
Third Factor: Certificate
Certificates function as proof of completing the relevant course and learning the related skills. If you’re enrolling in an online Kotlin course for professional reasons, it’s important to choose a program that includes a shareable certificate of completion.
A certificate will show your prospective employer that you have the Kotlin skills touted on your resume and cover letter. While many training programs and courses provide certificates, some don’t. If you don’t have any professional goals, you might not care about whether or not a certificate is provided.
Kotlin Course Certificates vs Certifications
Certificates and certifications have two distinct functions. Kotlin course certificates are awarded to students who complete an associated course. Kotlin certifications are awarded after you pass an associated professional exam, and they are a form of gatekeeping that proves your eligibility to work in a given role or field.
Importance of Kotlin Certifications
Kotlin certifications are one of the best ways to enter the field or advance your career within the field. They prove to employers that you’re up to speed with the latest trends in Kotlin and are equipped to handle the demands of a mobile app development career.
Why You Should Take Online Kotlin Courses or Classes
If you want to become an Android developer but you only know Java, it’s time to switch to Kotlin. Kotlin is a secure and more concise way to code for Android or JVM. You’ll benefit from its interoperability and functionality in creating reliable applications.
Online Kotlin courses or classes allow you to take advantage of this knowledge in a flexible, accessible, and affordable way. The app industry is moving towards the wholesale adoption of the Kotlin language, and if you want to stay relevant in the industry, you’ll need to do the same.
