Lecture 6 - Java Platform Overview | Java Full Course 2023

In this tutorial, we will learn about Java and its different platforms. Java is a widely used programming language for developing applications for different types of devices such as desktops, mobile devices, and web servers. There are separate platforms dedicated to developing applications for these devices, and this course focuses on one such platform called Java SE.

To run Java programs, we need to install the latest version of Java SE. This course provides a solid understanding of what Java SE platform is all about. The Java software family includes multiple platforms targeting different types of devices, and the three main platforms are Java Standard Edition (Java SE), Java Enterprise Edition (Java EE), and Java Micro Edition (Java ME).

Java SE is used to develop standalone applications that typically run on desktops but may also run on servers. Java EE is used to develop enterprise applications that run on web servers, while Java ME is used to develop applications for resource-constraint devices like cell phones.

This course mainly focuses on Java SE, which represents the core Java programming language. However, it is essential to have a solid foundation in Java even if you want to develop Java EE or Java ME applications because the technologies used in these platforms are built on top of Java, and many of the Java language features are used in these platforms.

In this tutorial, we will also learn about the two versions of Java SE: the Java Runtime Environment (JRE) and the Java Development Kit (JDK). JRE is used to run Java applications, while JDK is used for both developing and running Java programs. JDK comes with several tools, including the Java compiler, and it also includes the JRE.

Overall, this tutorial provides a great introduction to Java SE and its importance as a foundation for developing applications for different types of devices.
