Java virtual machine?
That refers to the Java runtime environment - the program required to run Java programs.
A JVM (Java Virtual Machine), which is a compiler for the compiled Java files, has to be installed on the machine where you want to run the Java program.

No, the Java is not machine language. Java is a high-level programming language that compiles to byte code suitable for interpretation into machine code by the Java virtual machine. In other words, you program the virtual machine rather than the physical machine. Once compiled, the byte code can be executed upon any machine with a Java virtual machine implementation.
Java is a programming language and a virtual machine that a java program can run in. The virtual machine allows the same Java application to run on many different types of computer, since the virtual machine remains identical. A Java applet is a special type of Java application that is coded specially to run as a plug-in to a web browser.
The whole idea of Java is to be able to run the same program on different types of computers (different "platforms" - combination of hardware and operating system). The Java Virtual Machine is what makes this possible. The Java program is compiled, not for a particular microprocessor, but for the Java Virtual Machine - a "virtual processor", so to speak. This JVM then interprets the compile program.
Java is defined by a specification and consists of a programming language, a compiler, core libraries and a runtime (Java virtual machine) The Java runtime allows software developers to write program code in other languages than the Java programming language which still runs on the Java virtual machine. The Java platform is usually associated with the Java virtual machine and the Java core libraries.
the Java virtual machine is an interpreter. It translates byte code into machine coded subroutines. the Java compiler produces the byte code. The byte code can be executed upon any Java virtual machine without modification, regardless of the underlying hardware. The Java compiler creates the byte code from the high-level source code.
A Java Virtual Machine (JVM) is a set of computer software programs that use a virtual machine model for the execution of Java computer programs and scripts. The JVM accepts data in a form commonly referred to as Java bytecode. This language conceptually represents the instruction set of a stack-oriented, capability architecture.
Java byte code is the code that is output by the Java compiler. Byte code is not machine code, it must be interpreted to create the machine code. This is handled by the Java virtual machine. Pretty much every platform produced today has a Java virtual machine implementation, so the same byte code can be executed upon any machine. Byte code can be regarded as being the native language of the virtual machine, as opposed…
A Java Virtual Machine enables a set of computer software programs and data structures to use a virtual machine model for the execution of other computer programs and scripts. The model used by a JVM accepts a form of computer intermediate language commonly referred to as Java bytecode. A virtual machine is a software implementation of a machine (i.e. a computer) that executes instructions (not programs) like a physical machine.
