A list of the most important key features of Java programming is given below-
Simple
Java is easy and simple to use and learn. It is derived from C and C++ languages, and many features are added from these languages.
Object Oriented
C++ is semi-object-oriented, but Java is a fully object-oriented language, except that it supports primitive data types. It has all OOP features, such as Class, Object, Inheritance, Abstraction, and Polymorphism.
Platform Independent
Java uses the Java virtual machine as an abstraction and doesn’t access the operating system directly. This makes Java programs highly portable. A Compiled java program (Java class) can be run without any modification on all supported platforms, e.g., Windows and Linux.
Robust
With automatic garbage collection and simple memory management schemes, exception handling features, generics support, and no pointers like C++, Java guarantees programmers a highly reliable application.
Portable
The byte code of a Java program is portable, which means we can compile it on any machine and can run this byte code on any device. This feature makes Java so popular and strong.

Secured
The Java platforms are designed with security features and runtime systems such as static type checking at compile time and runtime checking, which let us concentrate more on application creation rather than the security of invading applications from outside.
Interpreted and compiled language
Java source code is converted into the byte code format, which does not depend on the target platform. The Java virtual machine will interpret these byte code instructions. So when we compile Java code, it completes in a two-step process. First, compile to byte code by using the javac command. Then this compiled program can be run using the java command that starts a java runtime environment.
High Performance
Due to the usage of intermediate byte code, Java's performance is impressive for an interpreted language.
Multi-threaded
Java is ‘multi-threaded,’ which supports ‘multitasking’ functionality. In Java, multiple independent threads can complete their jobs at the same time to utilize the CPU more and consume time. Multithreading is a built-in feature in Java.
Distributed
Java handles TCP/IP protocols, making it ideal for Java for the distributed environment of the Internet. 
Java also supports Remote Method Invocation (RMI). This feature enables a program to invoke methods across a network.
Dynamic
Java can link in new class libraries, methods, and objects dynamically.
Java can also determine the class type through a query, making it possible to either dynamically link or terminate the program.

Flexibility at the core
Java SE version 8 (JDK 8) has various functional programming features like interfaces and Lambda Expressions. With such unique features of the Java programming language, they add to its flexibility.

Networked
Java is mainly designed for web-based applications. Java masks a lot of complexity by providing classes for you that already implement the complex parts, such as creating socket connections, reading the URL contents as a file, etc. Moreover, J2EE is used for developing network-based applications.
