Question

Which component is used to compile, debug and execute the Java program?

• A. JRE
• B. JIT
• C. JDK
• D. JVM

Hint:

Use JDK for developing Java programs; JRE/JVM are only for running them.

Answer 1

The Correct Option is C

Step 1: Role of JDK.
The Java Development Kit (JDK) is a complete software development kit required for compiling, debugging, and running Java programs.

Step 2: Difference from JRE and JVM.
- JRE (Java Runtime Environment) is only for running programs, not compiling.
- JVM (Java Virtual Machine) executes the bytecode, but cannot compile.
- JIT (Just-In-Time compiler) is a part of JVM to speed execution. Thus, the correct development tool is JDK.

Final Answer: \[ \boxed{\text{JDK}} \]
