In Java, reserved words, commonly known as keywords, are predefined identifiers that have specific meanings in the programming language. These keywords are case-sensitive, meaning the Java compiler differentiates between uppercase and lowercase letters. All Java keywords are written in lowercase. For example, keywords such as `class`, `public`, `static`, `void`, and `if` are always used in lowercase and will result in errors if they are written in any other case, such as uppercase or mixed case. This strict adherence to lowercase for reserved words is a fundamental aspect of Java's syntax that helps maintain clarity and consistency among programmers. Understanding this convention is crucial when writing Java code, as it helps to avoid syntax errors that could arise from incorrectly casing keywords.
