Which program is used to compile Java source code into bytecode? a. javap b. javac c. java d. javad

Break Down the Problem

1. Identify the objective: We need to determine which program compiles Java source code into bytecode.
2. Examine the options: We have four options to evaluate: javap, javac, java, and javad.

Relevant Concepts

1. javap: This is a disassembler for Java class files. It does not compile code but rather allows users to view the structure of class files.
2. javac: This is the Java compiler that converts Java source code (.java files) into bytecode (.class files).
3. java: This is the Java Runtime Environment (JRE) launcher that runs Java applications. It does not compile code but executes compiled bytecode.
4. javad: This option is not a standard Java tool and does not exist within the Java Development Kit (JDK).

Analysis and Detail

• Given these definitions, it becomes clear that javac is specifically designed for compiling Java source code into bytecode, while the other options serve different purposes.

Verify and Summarize

• Upon verification of the functions of each option, javac stands out as the correct answer. It serves a fundamental role in the Java programming environment by transforming code written by developers into a format that the Java Virtual Machine (JVM) can understand and execute.

Final Answer

The correct answer is b. javac.
