In Java, does 'public Class HelloPrinter' and 'public Class helloprinter' refer to the same class?

In Java, class names are case-sensitive, meaning that 'HelloPrinter' and 'helloprinter' are treated as entirely different identifiers. Each class name must be unique within its scope, and the case of each letter contributes to how the language distinguishes between different class names. This feature allows developers to define multiple classes with names that differ only in capitalization, which can be useful for organizing code in a meaningful way.

While some languages may be case-insensitive, Java's adherence to case sensitivity enforces a stricter naming convention that avoids potential conflicts and improves clarity. This sensitivity means that programmers must be careful when naming classes and invoking them to ensure that they match the exact casing used during their declaration. Thus, 'HelloPrinter' and 'helloprinter' do not refer to the same class and are completely distinct as far as the Java compiler is concerned.
