Example of a lexical error, detected by the scanner in Java.

A) Syntax error
B) Runtime error
C) Semantic error
D) Spelling error

Answer 1

A lexical error in Java refers to a spelling error detected by the scanner during the lexical analysis phase.

Step-by-step explanation:

A lexical error in Java refers to a spelling error that is detected by the scanner. This occurs when a word or identifier is misspelled or used in an incorrect way.

For example, if a variable name is misspelled in the code, it would be considered a lexical error. The scanner, which is a part of the compiler, identifies these errors during the lexical analysis phase.

Lexical errors are different from other types of errors such as syntax errors, which involve incorrect usage of programming language syntax, runtime errors, which occur while the program is running, and semantic errors, which involve incorrect meaning or logic in the program.
