Question: 1 / 510

If 'a' is an object and 'b' is an object and you assign 'a = b;' in Java, and then modify 'a', what happens to 'b'?

It is modified as well

When we assign 'a = b;' in Java and then modify 'a', 'b' is also modified because both 'a' and 'b' are referencing the same object. Therefore, any changes made to 'a' will also be reflected in 'b'. Option B is incorrect because 'b' is not a copy of 'a' but rather a reference to the same object. Option C is incorrect because the assignment of 'a' to 'b' does not nullify 'b' in any way. Option D is incorrect because 'b' does not get a copy of modifications made to 'a', but rather the original modifications themselves.
