Java : Highly recognized for its portability and scalability across multiple platforms from mainframe data centers to smartphone, Java is one of the oldest and in-demand computer programming languages being used in the present-day world. Having been in popular demand, Java is extensively used in Android development along with Desktop Applications, Scientific Applications, Web Applications, etc. Apart from it, top-notch companies like Adobe, Amazon, Flipkart, etc use JAVA, promising magnified career opportunities to Java developers.

Ideal for distributed computing, Java’s demand in the tech-world, huge community support, popular frameworks such as Spring, Hibernate, Strut and several enriching features like multithreading, automatic memory allocation & garbage collection, platform independency, etc. ascertains that JAVA would provide you numerous professional opportunities in the upcoming years.

3. Python : A fast, easy-to-use, and easy-to-deploy programming language that is being widely used to develop scalable web applications, Python is one of the fastest growing general purpose, high-level programming languages with an emphasis on code readability. Python programming can help you perform almost anything. Even the new specializations and upcoming technologies including Artificial Intelligence, Big Data, Networking, Machine Learning, rely on Python Programming. 

The rapid advancement in Information Technology has amplified the demand for python developers and programmers. An average salary of a python developer, in popular frameworks such as Django, Flask, Pyramid, in USA is around $120,000 while in India it is around ₹1.2 Million.

4. Kotlin : After Google declared Kotlin as the most preferred language for Android Application development, the developers have immensely shown their inclination towards the language. A statically typed general-purpose programming language, Kotlin does not only support object-oriented but also functional programming features. The language is relatively easier to learn, interoperable with Java and can also be used for web development, desktop application development, etc.
