Question 239 of 509
Quick Answer
The correct answer is the `char` primitive type, which is specifically designed to store a single character in Java. This is because `char` is a 16-bit unsigned integer data type that holds a single Unicode character, ranging from '\u0000' (0) to '\uffff' (65535), allowing it to represent letters, digits, symbols, and even characters from international scripts. On the Oracle Java Foundations 1Z0-811 exam, this question tests your understanding of Java’s eight primitive types and their specific purposes, often appearing as a straightforward multiple-choice item where distractors like `String` (a reference type) or `int` (which stores numbers, not characters) are common traps. A key memory tip is to remember that `char` is the only primitive type that uses single quotes, as in `'A'`, while `String` uses double quotes—so if you see single quotes, think `char`.
1Z0-811 Primitives, Strings and Operators Practice Question
This 1Z0-811 practice question tests your understanding of primitives, strings and operators. 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.
Which primitive type can store a single character?
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
✓
char
Option D is correct because the `char` primitive type in Java is specifically designed to store a single 16-bit Unicode character, ranging from '\u0000' (0) to '\uffff' (65535). It is the only primitive type that directly represents a character value, making it the appropriate choice for storing a single character.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Oracle often tests the distinction between primitive types and reference types, and the trap here is that candidates mistakenly choose `String` because they associate it with characters, forgetting that `String` is not a primitive type and is designed for sequences, not single characters.
Detailed technical explanation
How to think about this question
The `char` primitive type in Java is unsigned and uses UTF-16 encoding, meaning it can represent Unicode characters directly, including supplementary characters via surrogate pairs. Under the hood, a `char` is stored as a 16-bit unsigned integer, which allows it to hold values from 0 to 65,535, corresponding to Unicode code points in the Basic Multilingual Plane (BMP). In real-world scenarios, using `char` is essential for low-level text processing, such as parsing individual characters from user input or handling character encoding conversions.
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.
