What is the main task of the JDK and why is it necessary for Java development?

JDK (Java Development Kit) is a developer kit for Java that includes everything necessary for creating, compiling, and running Java applications. The main purpose of the JDK is to provide tools and libraries such as the javac compiler, standard Java classes, debugger, and JVM (Java Virtual Machine).

Without the JDK, it is impossible to write and compile Java code, as it contains the compiler and libraries needed to convert source code into bytecode and execute it subsequently. Therefore, the JDK is essential for Java development as it provides a complete set of tools for creating and testing applications.
