Java MCQ: What is the size of an int variable in Java?
Answer:
Explanation:
In Java, the int data type is a 32-bit signed integer. This means it has a fixed size of 32 bits, which is equivalent to 4 bytes. The range of values it can hold is from -2,147,483,648 to 2,147,483,647. Java is designed to be platform-independent, so the size of primitive data types like int remains consistent across different operating systems and hardware platforms.
Understanding the size of data types is essential for memory management and performance optimization in Java programming. Knowing the range and limitations of int can help you choose the appropriate data type for your variables, especially when dealing with large numbers or performance-critical applications.
