Abstraction, on the other hand, entails obscuring the details of an object from the user. These features, combined with Java’s stringent security policies, make it a secure language for various applications.

Platform Independence

One of the most cherished features of Java is its platform independence, which empowers developers to compose code once and execute it on any platform with a Java Virtual Machine (JVM). This feature is known as the Write Once Run Anywhere (WORA) approach, and it enables Java programs to be executed on any system that has Java installed. Additionally, Java supports remote method invocation, allowing for seamless communication between distributed applications.

The Java Virtual Machine (JVM) serves as an abstraction layer between the code and the hardware, allowing Java programs to be executed on any platform that supports a JVM. This independence makes Java a popular choice for:

• web applications

• mobile apps

• cloud computing

• big data projects

These types of projects often require cross-platform compatibility.
