Datatypes

807569

HI All,

The following query might look absurd in context to java, but I was asked this question at an interview with a very reputed organization. Please help and provide me a solution:

Is there a way to determine the size of primitive datatypes in java? (Like, C/C++ provides the sizeof() operator)

Thanks and regards,

The correct answer is: No.

There is a definition in the JVM specification that tells you the range of primitive types from which you can deduct the mimimum size. But there's no reliable way to find the amount of memory used by a primitive value.
