In this Article we present you why it is difficult in java to measure the size of an object, we also narrate the traditional method used by programmers to measure the size of objects in java and then we present to you the latest and most accurate way to measure the size of an object.

This is because in C programmers have to manually allocate memory using malloc().In java, memory allocation and object construction are both tied together, This makes it more difficult to find the size of an object.
