this is a fill in the black question.

1) The result of compiling a java source file is a file with the extension that contains

what, haven't you compiled any java source files yet? What come out?

there's no java code for this question

so what? They would not ask you such a question if you were not familiar with java code and compiling it (with javac).

If still unsure, just google the topic. Or run javac on some of your own java code.

the compiled bytecode.

To get the answer to this question, you can follow these steps:

1. Understand the question: The question is asking for the file extension that contains the result of compiling a Java source file.

2. Know about Java source files: Java source files are files that contain the human-readable code written in the Java programming language. They typically have the file extension ".java".

3. Understand the compilation process: In Java, the compilation process translates the human-readable code written in the Java source file into a machine-readable format known as bytecode. This step is performed by the Java compiler.

4. Identify the file extension for compiled bytecode: The compiled bytecode is stored in files with the file extension ".class". These files contain the translated version of the Java source code, which can be executed by the Java Virtual Machine (JVM).

Therefore, the answer to the question is: "The result of compiling a Java source file is a file with the extension '.class' that contains the compiled bytecode."
