It is an object-oriented language, which means that it is based on the concept of objects, which can contain data and code that manipulates that data. Some of the key features of Java include its portability, which allows programs written in the language to run on any platform that supports Java, and its security, which makes it a good choice for developing applications that handle sensitive information. Java is also a platform-independent language, which means that programs written in the language can be run on any operating system that supports Java.
