[@debaduttadas2331]

Normal map we get concurrent modifiable exception when one iterator is iteratating and other iterator tries to update anything.Hence iterator of hash map is fail fast

[@pratikdutta501]

little correction "concurrent modification exception"

[@pratapjavasingh3239]

Default size not 10 it's 16 and in a hashmap and when we insert as a Single null key then hashmap treats as first' indexed in 0 place

[@JavaTechLead]

correct

[@2011ganga]

And when default size filled with 75% , it will automatically increases size by 2X time. i.e will become 32
