Question 431 of 481
1Z0-811 Java Basics and Syntax Practice Question
Which primitive data type should be used to store a single character?
⚠ Common exam trap
Oracle often tests the distinction between primitive and reference types, and the trap here is that candidates confuse `String` (a reference type) with `char` (a primitive type) because both are used for text, leading them to incorrectly select `String` for a single character.

Correct answer & explanation
✓
char
The `char` primitive data type in Java is specifically designed to store a single 16-bit Unicode character, ranging from '\u0000' (0) to '\uffff' (65,535). It can represent any character in the Unicode standard, including letters, digits, and symbols, making it the appropriate choice for a single character value.
