Which component is used to compile, debug and execute java program?JREJITJDKJVM

The component used to compile, debug, and execute a Java program is the JDK (Java Development Kit). Here's a step-by-step explanation:

1. JDK (Java Development Kit): This is the core component of Java Environment and provides all the tools, executables, and binaries required to compile, debug, and execute a Java Program. The JDK is a kit that provides the environment to develop and execute (run) the Java program. The JDK includes the Java Runtime Environment (JRE), an interpreter/loader (Java), a compiler (javac), an archiver (jar), a documentation generator (Javadoc), etc.

2. JRE (Java Runtime Environment): It provides the minimum requirements for executing a Java application; it consists of the Java Virtual Machine (JVM), core classes, and supporting files.

3. JVM (Java Virtual Machine): This is an abstract machine. It is a specification that provides a runtime environment in which Java bytecode can be executed. It can also run those programs which are written in other languages and compiled to Java bytecode.

4. JIT (Just-In-Time) compiler: It is a part of the Java Runtime Environment that improves the performance of Java applications by compiling bytecodes to native machine code at run time. The JIT compiler complements the JVM.

So, to compile, debug, and execute a Java program, you primarily need JDK.
