What is the size of int in Java?
32-bit
int: By default, the int data type is a 32-bit signed two’s complement integer, which has a minimum value of -231 and a maximum value of 231-1. In Java SE 8 and later, you can use the int data type to represent an unsigned 32-bit integer, which has a minimum value of 0 and a maximum value of 232-1.

How do you find the size of an object in Java?
One way to get an estimate of an object’s size in Java is to use getObjectSize(Object) method of the Instrumentation interface introduced in Java 5. As we could see in Javadoc documentation, the method provides “implementation-specific approximation” of the specified object’s size.

How do you get the size of an array in Java?
To find the length of an array, use array data member ‘length’. ‘length’ gives the number of elements allocated, not the number inserted.
What is the size of an object?
Size in general is the magnitude or dimensions of a thing. More specifically, geometrical size (or spatial size) can refer to linear dimensions (length, width, height, diameter, perimeter), area, or volume. Size can also be measured in terms of mass, especially when assuming a density range.
