Why Should I Learn Java Language?

Java is one of the most popular programming languages used by software developers today. It is the core language used in developing Android apps, and is also commonly used in back-end web development. If you’re new to programming and want to enter either of these fields, this course is a great place to get started.

Even if you don’t have a career trajectory in mind, Java programming is a great option for first-time coders due to its popularity and ease of use. This course will provide you with a solid foundation in computer science and Object Oriented Programming concepts, as well as set you on the path for success as a software engineer.

Java Overview

Java technology is used to develop applications for a wide range of environments, from consumer devices to heterogeneous enterprise systems. In this section, get a high-level view of the Java platform and its components. 

The garbage collector

Rather than forcing you to keep up with memory allocation (or use a third-party library to do so), the Java platform provides memory management out of the box. When your Java application creates an object instance at runtime, the JVM automatically allocates memory space for that object from the heap a pool of memory set aside for your program to use. The Java garbage collector runs in the background, keeping track of which objects the application no longer needs and reclaiming memory from them. This approach to memory handling is called implicit memory management because it doesn't require you to write any memory-handling code. Garbage collection is one of the essential features of Java platform performance. 

The Java Runtime Environment

The Java Runtime Environment (JRE; also known as the Java runtime) includes the JVM, code libraries, and components that are necessary for running programs that are written in the Java language. The JRE is available for multiple platforms. You can freely redistribute the JRE with your applications, according to the terms of the JRE license, to give the application's users a platform on which to run your software. The JRE is included in the JDK.
