- A
The compiler searches for source files in the `bin` directory.
Why wrong: `-d` specifies output directory, not source directory.
- B
The compiled .class files are placed in the `bin` directory maintaining the package structure.
`-d bin` sets the root for output; the class file will be at `bin/com/example/App.class`.
- C
The compiler creates a JAR file named `App.jar` in the `bin` directory.
Why wrong: `javac` does not create JAR files; that is done by `jar` tool.
- D
The compiler compiles the code into a named module.
Why wrong: Compiling into a module requires module-info.java and additional flags like `--module-source-path`.

1Z0-811 Exception Handling and Development Tools Practice Question
This 1Z0-811 practice question tests your understanding of exception handling and development tools. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer compiles a Java application using the command `javac -d bin src/com/example/App.java`. Which of the following is true?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The compiled .class files are placed in the `bin` directory maintaining the package structure.
The `-d` option in the `javac` command specifies the destination directory for compiled `.class` files. When `-d bin` is used, the compiler places the `.class` files into the `bin` directory, preserving the package directory structure (e.g., `bin/com/example/App.class`). This is the standard behavior for organizing compiled output separately from source code.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The compiler searches for source files in the `bin` directory.
Why it's wrong here
`-d` specifies output directory, not source directory.
- ✓
The compiled .class files are placed in the `bin` directory maintaining the package structure.
Why this is correct
`-d bin` sets the root for output; the class file will be at `bin/com/example/App.class`.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
The compiler creates a JAR file named `App.jar` in the `bin` directory.
Why it's wrong here
`javac` does not create JAR files; that is done by `jar` tool.
- ✗
The compiler compiles the code into a named module.
Why it's wrong here
Compiling into a module requires module-info.java and additional flags like `--module-source-path`.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Oracle often tests the misconception that `-d` specifies the source directory or that `javac` can produce JAR files, leading candidates to confuse the roles of `javac` and `jar` tools.
Trap categories for this question
Command / output trap
`-d` specifies output directory, not source directory.
Detailed technical explanation
How to think about this question
The `-d` option is essential for separating source and compiled code in larger projects, preventing clutter and enabling clean builds. Under the hood, `javac` parses the package declaration in the source file (e.g., `package com.example;`) and creates the corresponding directory hierarchy under the specified `-d` directory. This behavior is defined in the Java Language Specification and is consistent across all standard JDK versions.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 1Z0-811 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
