If two identifiers differ only by case, are they considered the same in Java?

If two identifiers differ only by case, are they considered the same in Java?

• A. Yes
• B. Sometimes
• C. Only for primitive types
• D. No

Answer: (D)

In Java, identifiers are case-sensitive. Two names that differ only by capitalization are treated as distinct identifiers. That means you can have both count and Count in the same scope, each referring to its own variable (for example, int count = 1; int Count = 2;). You must use the exact capitalization when referring to them, otherwise the compiler won’t recognize the symbol. This applies to all kinds of identifiers, including variables, methods, classes, and fields. So, two identifiers that differ only by case are not the same in Java.
