Java is an object-oriented programming language.

Explanation:
Java is a high-level, object-oriented programming language that was developed by Sun Microsystems and released in 1995. It was designed to be platform-independent, meaning that Java programs can run on any operating system or platform as long as a Java Virtual Machine (JVM) is installed.

Object-Oriented Programming:
Java is primarily an object-oriented programming (OOP) language. This means that it follows the principles of OOP, such as encapsulation, inheritance, and polymorphism. In Java, everything is treated as an object, including variables, functions, and even the programs themselves. This allows for modularity, reusability, and easier maintenance of code.

Platform Independence:
One of the key features of Java is its platform independence. Java programs are compiled into bytecode, which is a platform-neutral format. This bytecode can then be executed on any system that has a JVM, making Java programs highly portable. This is in contrast to platform-dependent languages, where the compiled code is specific to a particular operating system or hardware architecture.

Java Virtual Machine:
The Java Virtual Machine (JVM) is an essential component of the Java platform. It is responsible for executing the bytecode generated by the Java compiler. The JVM acts as an interpreter, translating the bytecode into machine code that can be understood and executed by the underlying operating system. This allows Java programs to run on any device or platform that has a compatible JVM installed.

Support for Multiple Inheritance:
Java does not support multiple inheritance, which is the ability for a class to inherit from more than one superclass. This was a deliberate design choice to keep the language simple and prevent certain programming issues that can arise from multiple inheritance. Instead, Java supports single inheritance, where a class can inherit from only one superclass, but it can implement multiple interfaces.

In conclusion, the statement "Java is an object-oriented programming language" is true. Java's object-oriented nature, platform independence, and support for single inheritance are some of the key reasons for its popularity and widespread use in various domains, including web development, mobile app development, and enterprise software development.
