What is java?

Question

I don't understand java. How does it work? what exactly is it? An app or a program or something else?

Answer 1

Java is a programming language to create programs that are compiled via the java compiler and run on a virtual machine installed on your computer. think of the Java Virtual machine as a playstation emulator installed on your pc.
Java applications run in the Java Virtual Machine as playstation games run on the emulator.
in conclusion to tun java applications you need to have the Java Virtual Machine installed on the system you want the application to run.
to do that you can download the latest JDK from the Oracle website and install it on your system: in that way you can also compile the programs you write.
