Why Java identifiers are case-sensitive?

Case insensitivity describes a programming language’s inability to distinguish between upper and lower case versions of a letter in the language’s character set .

In computers, case sensitivity defines whether uppercase and lowercase letters are treated as distinct (case-sensitive) or equivalent (case-insensitive) . For instance, when users interested in learning about dogs search an e-book, “dog” and “Dog” are of the same significance to them.
