The programs are written in Java typically run faster than corresponding Python programs and slower than C++. When compared with Python, Java kind of fits between C++ and Python.One more example, since there are no pointers, bad memory access is also not possible. So we cannot pass large objects (like we can do in C++) to functions, we always pass references in Java. For example, non-primitives are always references in Java. When compared with C++, Java codes are generally more maintainable because Java does not allow many things which may lead to bad/inefficient programming if used incorrectly.Java is used in all kinds of applications like Mobile Applications (Android is Java-based), desktop applications, web applications, client-server applications, enterprise applications, and many more.Also, Java codes are always written in the form of classes and objects. But Java does not provide low-level programming functionalities like pointers.

Then the byte code runs on Java Virtual Machine (JVM) regardless of the underlying architecture. The Java codes are first compiled into byte code (machine-independent code).However, it is not considered as pure object-oriented as it provides support for primitive data types (like int, char, etc) Java has been one of the most popular programming languages for many years.Java is one of the most popular and widely used programming languages.
