What does the following statement mean?

Assigning references does not copy the state of the source object on the right hand side, only the reference value.

What is exactly, the state of the source object?
Thanks

In this context, the state of the object can be thought of as the actual object binary pattern. When you assign one reference to another, the original object remains intact, while the contents of the assigned reference (its binary pattern) gets copied into the reference variable to the left, so both references refer to the same object on the heap. Remember, when you use == operator, you compare the bit patterns?
This has to do with the Java pass-by-value notation - everything is passed by value, even references.
