Can the JDK compile Java programs?

Can the JDK compile Java programs?

• A. No.
• B. Only with JRE.
• C. Only in a specialized environment.
• D. Yes.

Answer: (D)

The JDK is specifically the toolkit that includes the Java compiler (javac) along with other development tools. This compiler translates your Java source files (.java) into bytecode (.class) that the Java Virtual Machine can execute. Because compiling is part of what the JDK provides, it can indeed compile Java programs. The JRE, on the other hand, is focused on running code and does not include a compiler, so it cannot compile. That’s why the correct choice is Yes. The idea that you’d need the JRE or a specialized setup isn’t accurate for standard Java development—the JDK includes the full toolchain you need to compile.
