Question

Which of the following variables defined inside methods or blocks in Java?

• A. File variable
• B. Class variable
• C. Instance variable
• D. Local variable

Hint:

{Local variables} exist only within the method or block where they are declared and cannot be accessed outside it.

Answer 1

The Correct Option is D

Step 1: Understanding variables in Java.
In Java programming, variables are used to store data values that can be used and modified during program execution. Java supports different types of variables depending on where they are declared and how they are used in a program.
Step 2: Types of variables in Java.
There are mainly three common types of variables in Java:
Local variables: These variables are declared inside a method, constructor, or block of code. They are accessible only within that specific block where they are defined.
Instance variables: These variables are declared inside a class but outside methods. They belong to objects of the class.
Class variables (static variables): These are declared using the static keyword and are shared by all objects of the class.
Step 3: Evaluating the options.
(A) File variable: Incorrect. Java does not define a variable type called file variable.
(B) Class variable: Incorrect. These are declared inside a class but outside methods.
(C) Instance variable: Incorrect. These belong to objects of a class and are declared outside methods.
(D) Local variable: Correct. These variables are declared inside methods or blocks.
Step 4: Conclusion.
Thus, the variable defined inside methods or blocks in Java is called a Local Variable.
Final Answer: Local variable
