What is the size of a Boolean variable in java?A. 1 Bit B. 1 Byte C. 2 Byte D. 8 Bit E. Depends on JVMF. A and B Both

Break Down the Problem

1. Identify what a Boolean variable is in Java.
2. Determine the size of a Boolean variable as per Java specifications and JVM implementation.

Relevant Concepts

• In Java, a Boolean variable can hold two values: true or false.
• The official Java specification does not define the storage size of a Boolean type explicitly in terms of bits or bytes.

Analysis and Detail

1. In Java, Boolean variables are commonly thought to use a minimal amount of space, potentially as low as 1 bit to signify true or false.
2. However, due to practical implementations and the way memory is managed in Java, a Boolean is typically represented using 1 byte (8 bits) in most JVMs. This is because memory is organized in bytes, and allocating a full byte for a logic representation simplifies memory alignment and access.
3. Some implementations might align Booleans in a way that uses multiple bytes, but this practice varies with different JVMs.

Verify and Summarize

• The most practical size for a Boolean variable in Java is 1 byte (commonly, 8 bits).
• While theoretically it could be as small as 1 bit, JVM implementations standardize the size to 1 byte in order to optimize performance and adhere to modern hardware architecture.

Final Answer

B. 1 Byte is typically the size of a Boolean variable in Java, although the theoretical size can be considered as 1 bit. Some might argue F (A and B Both) in context of theoretical versus practical implementations, but the best answer is B.
