What is the role of JVM in Java programming?

The JVM has two primary functions: to allow Java programs to run on any device or operating system (known as the “Write once, run anywhere” principle), and to manage and optimize program memory.

What are the most important features of Java How does Java achieve platform independence?

Being platform-independent means a program compiled on one machine can be executed on any machine in the world without any change. Java achieves platform independence by using the concept of the BYTE code. The Java compiler never converts the source code to machine code like that of the C/C++ compiler.

Why is Java powerful language?

Object-Oriented Programming- Object Oriented Programming methodology simplifies program writing and thus allows the programmers to deal with complex and large programs. This is one of the many features that make Java a more powerful programming language than many others.

What is the use of JVM in Java?

JVM, i.e., Java Virtual Machine. JVM is the engine that drives the Java code. Mostly in other Programming Languages, compiler produce code for a particular system but Java compiler produce Bytecode for a Java Virtual Machine. When we compile a Java program, then bytecode is generated.

What is the difference between a compiler and a JVM?

JVM is the engine that drives the Java code. Mostly in other Programming Languages, compiler produce code for a particular system but Java compiler produce Bytecode for a Java Virtual Machine. When we compile a Java program, then bytecode is generated.

What is the full form of JVM?

Full form of JVM is Java Virtual Machine. JVM in Java is the engine that drives the Java Code. It converts Java bytecode into machines language. JVM architecture in Java contains classloader, memory area, execution engine etc. In JVM, Java code is compiled to bytecode.

What is the difference between JVM and JIT in Java?

JVM is the engine that drives the Java Code. It converts Java bytecode into machines language. In JVM, Java code is compiled to bytecode. This bytecode gets interpreted on different machines. JIT stands for Just-in-time compiler. JIT is the part of the Java Virtual Machine (JVM). It is used to speed up the execution time.
