  1. EDCDIC

  2. UNICODE

  3. ASCII

  4. Hexadecimal
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Java uses Unicode (UTF-16) as its native character encoding, with each char primitive representing a 16-bit Unicode value. This design enables built-in internationalization support. ASCII is 7-bit, EBCDIC is IBM's 8-bit mainframe encoding, and Hexadecimal is a numeric representation system.

AI explanation

To answer this question, you need to understand the 16-bit coding schemes used in Java programming.

Option A) EDCDIC - This option is incorrect because EBCDIC (Extended Binary Coded Decimal Interchange Code) is not a 16-bit coding scheme used in Java programming. EBCDIC is an 8-bit coding scheme used mainly on IBM mainframe computers.

Option B) UNICODE - This option is correct because Unicode is a 16-bit coding scheme used in Java programming. Unicode is a character encoding standard that assigns a unique code point to every character in various scripts and languages.

Option C) ASCII - This option is incorrect because ASCII (American Standard Code for Information Interchange) is a 7-bit coding scheme, not 16-bit. ASCII is widely used in early computer systems and programming languages, but it cannot represent all characters in various scripts and languages.

Option D) Hexadecimal - This option is incorrect because hexadecimal is a numbering system that uses base 16, not a coding scheme. Hexadecimal is commonly used in computer programming to represent binary values in a more human-readable form.

The correct answer is B) UNICODE. This option is correct because Unicode is the 16-bit coding scheme employed in Java programming.
