Core JAVA Training FAQ'S
Java is a high-level, object-oriented, reliable, secure, high-performance, multithreaded, and portable programming language. It is also platform-independent. In June 1991, James Gosling created it. Because it offers its own JRE and API, it can also be referred to as the platform.
By learning Core JAVA through VISWA Online Trainings, advance in your job.
JVM: JVM, which stands for Java Virtual computer, is an abstract computer that provides the environment for running Java bytecode. It is a specification that details how the Java Virtual Machine operates. Oracle and other businesses have given its implementation. JRE is the name of its implementation.
JVMs are available for many hardware and software platforms (so JVM is platform dependent). It is a runtime instance that is created when we run the Java class. There are three notions of the JVM: specification, implementation, and instance.
JRE: The Java Runtime Environment is known as JRE. It is how the JVM is implemented. A collection of software tools called the Java Runtime Environment is used to create Java programs. To offer the runtime environment, it is employed. It is how the JVM is implemented. It really does exist. It has a collection of libraries and additional files that the JVM uses during runtime.
JDK: JDK is an acronym for Java Development Kit. It is a software development environment that is used to develop Java applications and applets. It physically exists. It contains JRE + development tools. JDK is an implementation of any one of the below given Java Platforms released by Oracle Corporation:
- Standard Edition Java Platform
- Enterprise Edition Java Platform
- Micro Edition Java Platform
- Class(Method) Area: Class Area stores per-class structures such as the runtime constant pool, field, method data, and the code for methods.
- Heap: It is the runtime data area in which the memory is allocated to the objects
- Stack: Java Stack stores frames. It holds local variables and partial results, and plays a part in method invocation and return. Each thread has a private JVM stack, created at the same time as the thread. A new frame is created each time a method is invoked. A frame is destroyed when its method invocation completes.
- Program Counter Register: PC (program counter) register contains the address of the Java virtual machine instruction currently being executed.
- Native Method Stack: It contains all the native methods used in the application.
The hardware or software environment in which a piece of software is run is known as a platform. Platforms come in two flavours: hardware- and software-based. The platform is software-based and uses Java.
There are the following differences between the Java platform and other platforms.
- Java is a software-based platform whereas other platforms may be hardware platforms or software-based platforms.
- Java is executed on top of other hardware platforms whereas other platforms can only have the hardware components.
