arrays - Time Complexity for Java ArrayList -


i found other entries question dealt specific methods, nothing comprehensive. i'd verify own understanding of used methods of data structure:

o(1) - constant time:

isempty() add(x) add(x, i) set(x, i) size() get(i) remove(i)

o(n) - linear time:

indexof(x) clear() remove(x) remove(i)

is correct? help.

the best resource straight official api:

the size, isempty, get, set, iterator, , listiterator operations run in constant time. add operation runs in amortized constant time, is, adding n elements requires o(n) time. of other operations run in linear time (roughly speaking). constant factor low compared linkedlist implementation.
