Question

The word. Case is used in a switch statement. This word is a ......

• A. Key word in java
• B. Function in java
• C. Datatype in java
• D. None of these

Hint:

Java features over 50 reserved keywords (such as int, class, public, switch, case) that cannot ever be utilized as identifiers.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question asks us to identify the standard programming classification of the word ‘case‘ as it is utilized within a ‘switch‘ statement block in Java programming.


Step 2: Detailed Explanation:
In Java, as well as in many other core programming languages like C and C++, ‘switch‘ and ‘case‘ are reserved words that hold predefined, special meanings to the language compiler.
These reserved words cannot be redefined by the programmer or used as normal variable names, object names, or general identifiers.
Such predefined words are formally known as "keywords".
Therefore, the word ‘case‘ is a keyword in Java used specifically to define different conditional execution paths (or branches) within a ‘switch‘ block.


Step 3: Final Answer:
The word ‘case‘ is a Key word in java.

Answer 2

The word case appears inside a switch block in Java to label its branches. To classify what kind of word it is, let's check it against each of the four categories offered.

1. Key word in java: A keyword is a reserved word with a fixed, special meaning to the compiler that cannot be used as an identifier such as a variable or method name. The word case fits this description exactly: it cannot be declared as a variable, and it always plays the same structural role of marking a branch inside a switch block.
2. Function in java: A function (or method) is a named, callable block of code that is invoked using parentheses, such as myMethod(). The word case is never called or invoked like this; it is written directly before a value inside a switch block and has no callable body of its own, so it is not a function.
3. Datatype in java: A datatype specifies the kind of value a variable can hold, such as int, double, or boolean. The word case does not describe or hold any value by itself; it is a structural label, not a type declaration, so this classification does not apply.
4. None of these: Since case does correctly fit one of the given categories, keyword, this option is not applicable.

Having ruled out function and datatype, and confirmed that case behaves exactly like a reserved word, the correct classification is as a keyword.

Therefore, the correct answer is Key word in java.
