What is the difference between Java IDE and JVM?
Java Virtual Machine is a program that runs pre compiledJavaprograms, which mean JVM executes .class files (byte-code) and produces output. The JVM is written for each platform supported by Java included in the Java Runtime Environment (JRE). The Oracle JVM is written in the C programming language.
What do you get when you compile a java program?
The java interpreter or JVM (Java Virtual Machine) is not able to execute the java source code for a program. The java source code first needs to be compiled into bytecode that can be processed by JVM. Producing bytecode make the program platform independent as each platform has its own JVM. It is also possible to directly write bytecode, bypassing the need to compile, but that would be tedious job and also not good for security purpose as the compiler checks for various errors in a program.
Is it possible to define a java static method inside a main method?
Because, the main method is the starting point of the java program and if we need an object of that class even before the main can be invoked, it is not possible. Hence it is declared static so that the JVM Can acess the main method without having to instantiate that particular class
Is JVM is part of compiler?
no jvm is not a part of java compiler
Is Jvm in the system?
The JVM (Java Virtual Machine) is a part of the JRE (Java Runtime Environment).The JRE is comprised of the JVM and the Class Library.The JVM takes the java language and compiles it into Bytecode which can then be interpreted as machine code by the platform(OS). The JVM will compile byte code specific to the OS it is being deployed upon. The JVM allows the Java language to be platform independent.
Why it is not possible to execute java program on machine which does not have JVM installed on it?
when a java program is compiled it is converted into a non executable code which is byte code, and this byte code can only be interpreted by JVM. so a java program can't be executed on a machine which doesn't have JVM installed on it.

What is purpose of JVM?
JVM stands for Java Virtual Machine The JVM is the system in which our Java programs are executed.

What is difference between jvmjre and jdk?
JVM Stands for Java Virtual Machine. JVM is the virtual machine in which a java program gets executed. JRE stands for Java Runtime Environment. JRE is the runtime set up that is required by the JVM to execute java programs. JDK stands for Java Development Kit. JDK is the basic software that gets downloaded from sun's java website if anyone wants to use java.
What is meant by JVM in applets?
Answer: JVM is nothing but java virtual machine,it is a software used to convert the bytecode(highly optimizes set of instructions) to machine code. so, now applet is a small java program run by a web browser.thus now we can understand for what JVM is used or mean in applets.Answer: In other words, JVM (Java virtual machine) is simply the component used to run software written in the Java language.

How is it possible that the same Java program can run on different platforms?
Java source code is compiled into .class files, which are used by the Java Virtual Machine (JVM). The format of the .class file is the same for all platforms, and so the source code can be compiled the same way on each platform. The JVM, however, needs to be written to run on a specific platform. This is the part which converts Java bytecode to native bytecode, and is why you need to download the JRE (which contains the JVM) for a specific platform.

Is JVM a software or hardware?
JVM stands for Java Virtual Machine, it is software.
Is Java is platform dependent or independent?
Java is not machine dependent. High-level Java source code is compiled against the JVM which produces Java byte code, the lower-level native language of the JVM. At runtime, the JVM interprets the byte code to produce the required machine-dependent code. Every platform that supports Java has its own JVM, thus the same byte code can execute upon any supported platform. The translation from byte code to machine-dependent code is handled solely by the platform JVM.
