Description

In this course you will be learning Java programming.Java as a programming language offers some key benefits to any organization and learning it in depth will definitely make one’s career bulletproof.Java a very versatile language - not restricted to any one particular industry, making it usable everywhere.Used across all platforms ranging from Android development to Web development and REST APIs to Machine Learning, AI and automation. One of the earliest versions of Java was also used to remotely guide NASA’s Mars rover.Lastly, Java and related technologies are always in high demand. So you may eventually work on microservices or create other cloud native applications based on a different technology. But a strong foundation in Java will accelerate your learning and give you an edge like none other.The principles taught in this course and the method of teaching will encourage you to think like a programmer. This course is based on learning by doing methodology.  It would ensure retention of concepts and solidify your learning.Here is a glimpse of what you would learn in the course:Basics of JavaConcepts - Java compiler vs InterpreterJVM vs JDKJava PrimitivesJava Operators and Control StatementsObject Oriented Programming Concepts - Classes Objects (this and static)InheritanceAbstractionPolymorphismEncapsulationGenericsJava Collections FrameworkJava Functional ProgrammingJava Streams
