Which data type is used to store a single character in Java?

• A. int
• B. boolean
• C. char
• D. float

Answer: (C)

The ability to store a single character in Java is provided by the char primitive type. Char is a 16-bit unsigned code unit that holds a Unicode character, and you create a char with a character literal in single quotes, such as 'A' or '9'. This is distinct from strings, which hold sequences of characters, and from the other primitive types: int for whole numbers, boolean for true/false, and float for numbers with decimals. When you need to represent just one character, using char is the correct choice because it is specifically designed for that purpose and aligns with Unicode code points.
