Java alias mechanism and Java alias Mechanism

The basic type stores actual values instead of references to an object. Therefore, when assigning values to an object, you can directly copy the content of one place to another.

However, when assigning values to an object, the situation changes. When performing operations on an object, what we actually perform is to reference the object. Therefore, if "assign an object to another object", the "Reference" is actually copied from one place to another. This means that if c = d is used for the object, both c and d point to the object that only d points.
