To compile, and execute a program written in java, _______________ is required.Select one:a.JREb.JITc.JDKd.JVM

The correct answer is c. JDK.

Step 1: Understand the terms

• JRE: Java Runtime Environment. It provides the libraries, the Java Virtual Machine (JVM), and other components to run applets and applications written in the Java programming language.
• JIT: Just-In-Time compiler. It's a part of the runtime environment and improves the performance of Java applications by compiling bytecodes to native machine code at run time.
• JDK: Java Development Kit. It's a software development environment used for developing Java applications and applets. It includes the JRE, an interpreter/loader (java), a compiler (javac), an archiver (jar), a documentation generator (javadoc), and other tools needed in Java development.
• JVM: Java Virtual Machine. It's a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode.

Step 2: Answer the question To compile and execute a program written in Java, you need the Java Development Kit (JDK). The JDK includes the Java Runtime Environment (JRE) which you need to run Java programs, but it also includes the compiler (javac) which you need to compile Java programs. Therefore, the correct answer is c. JDK.
