Explain the features of the Java language?

Java is a simple language and can be learned quickly, making writing programs more accessible and faster. It follows the object-oriented programming (OOP) approach, which helps to maintain our code as the objects incorporate data and its behavior. The Java program is compiled to byte code that can run on any system, making it portable. Java is a platform-independent language, unlike C++ and C. It is not dependent on any operating system. Java doesn’t use pointers which makes it more secure as now the programmer cannot directly access the address spaces in memory. Java supports multithreading and is both an interpreted and compiled language.

How is JDK different from JRE and JVM?

Java Development Kit is a software dev environment used to create Java applications and applets. It exists physically and comprises JRE and development tools. JDK is an implementation of Java platforms that Oracle develops. JRE stands for Java Runtime environment, which implements Java Virtual Machine (JVM). It consists of software tools and other files used by JVM at runtime. JVM is an abstract machine used to provide a runtime environment where the byte code is executed. It is platform-dependent, and it is an instance created at runtime when a Java class is run. Specification, Instance, and Implementation are the three notions of JVM.

Explain the types of memory areas are there in the system?

There are many ways to allocate memory to the machine. When we declare an object of any class, the memory gets allocated. Class area stores per-class structures such as fields, runtime pool, methods, etc. Heap is the area where the memory is assigned to the objects of a class. Stack area store frames hold the partial results and local variables of a given scope in a program. Stack has a role in method invocation and the method's return value. Program Counter Register stores the address value of the JVM currently in execution. Native methods of an application also have their separate memory area.
