Could someone please help to clarify the over head figures for the Hashmap? It says 32 bytes per key value entry. Each Hashmap$Entry contains four items that are KeyHash and three other items of type object. So if each of these are 8 bytes then what he says about the entry overhead being 32 bytes is correct. But further down the slide he says overhead of Hashmap is 48 plus 36. But each entry has an overhead of 32 bytes. In essence it sould be 48 plus 32. So where do the additional 4 bytes come from when the slide says 48 plus 36? So I am slightly confused and appreciate it if anyone could shed some light on this issue. Many thanks
Really good presentation. Can I embed it on my blog? For now, it is just linked, but I would like to have it embedded there if You don't mind. @Oracle Learning Library
He is definitely my master ! , I learnt a lot from this lovely articulate presentation . Looking forward to get quick insights on subtle areas of programming
