What is the range of the char type in Java?

• A. 0 to 255
• B. 0 to 1024
• C. 0 to 65535
• D. 0 to 256

Answer: (C)

The char type in Java is a 16-bit unsigned integer that can represent characters using the Unicode standard. The Unicode standard allows for a wide range of characters, and Java's char type is capable of representing all of those characters. Specifically, it can take values from 0 to 65,535, which corresponds to the range of values that can be represented by a 16-bit integer. This range includes not only basic Latin characters but also characters and symbols from various writing systems around the world.

The other options provided do not accurately reflect the capabilities of the char type in Java. The range of 0 to 255, for instance, aligns with 8-bit values, which is insufficient for the full character set that Unicode provides. Similarly, options citing ranges of 1024 or 256 are also not representative of the actual size and structure of the char type in Java. Therefore, the choice indicating the range of 0 to 65,535 correctly captures the capacity of the char type within Java's data types.
