What is a Java Development Kit (JDK)? Why Do We Need It?

Introduction

In this blog, we will enhance further information about What is JDK in Java. The Java Development Kit (JDK) is a crucial element requires for software development. Technically, it is a Java Standard Edition or Java Enterprise Edition implementation.

What Is JDK in Java?

The initials JDK stand for Java Development Kit in Java. It includes the Java Runtime Environment (JRE) and Java Virtual Machine in contrast to a collection of software development tools and auxiliary libraries (JVM).

The Architecture of JDK in Java

The three important software modules of JDK are:

JDK (Java Development Kit)
JRE (Java Run-time Environment)
JVM (Java Virtual Machine)

JDK (Java Development Kit)

The Java Development Kit is a software development tool that creates a run-time context for the running of Java source code.

JVM (Java Virtual Machine)

A context for running Java source code is built by the Java Virtual Machine, a piece of software. JVM enables Java’s incredibly useful feature of “Write once and execute later.”

The Java Virtual Machine (JVM) executes programmes by converting Java source code into ByteCode (a machine language), all while staying completely on top of the host operating system.

JRE (Java Run-time Environment)

All Java source codes are run on a platform known as the Java Run-time Environment. JRE is in charge of including the jar files, support libraries, and software plugins requires for the source code to function.

After exploring the JDK in Java’s architecture, we will now continue and learn more about the JDK in Java’s components.

Components of JDK in Java

The following is a list of JDK’s core components for Java

Java

In the earlier SUN Java, it serves as the deployment launcher. It analyzes the source code generated by the javac compiler when installing the class files.

Javac

The java compiler is instructed by the javac to create bytecode from source code.

Javadoc

The comments added to the source code are documented by the javadoc.

Jar

The jar facilitates the management of the jar files in the package library by the archives.

jps

Java Virtual Machine Process Status Tool is known as jps. It controls the running JVMs for the active programme.

appletviewer

Without a web browser, Java applets can run and debugg using the appletviewer.

idlj

From a given Java IDL file, an IDL-to-Java compiler produces Java bindings.

javap

Acting as a file disassembler is the javap.

JConsole

A Java Management and Monitoring component is JConsole.

javah

A stub-generator called Javah is used, and C-Header is use to create native methods.

javaws

For JNLP applications, the javaws serves as the Web Start launcher.

jhat

A heap analysis tool is the jhat.

jmc

The acronym jmc stands for Java Mission Control.
