OCP Java SE11.1 Study Guide: typo in 4.6.3 Garbage collection for the exam

Post by kowenli »

In section 4.6.3 an example is given about garbage collection and objects' eligibility for garbage collection.

At step 7 of the example is written:
bar vs baz GC 2020-06-30 140905.png
bar vs baz GC 2020-06-30 140905.png (108.61 KiB) Viewed 10859 times
At line 9, a new object is created and assigned to baz. Thus, bar stops pointing to obj 1 and starts pointing to obj 3 after the execution of this line.
In my opinion this is a typo and should be:
At line 9, a new object is created and assigned to baz. Thus, baz stops pointing to obj 1 and starts pointing to obj 3 after the execution of this line.

I could not find this in the errata[1] under location "4.6.3", nor with search for "bar", "baz" and "garbage collection".
