java - Properly removing an Integer from a List<Integer> -

here's nice pitfall encountered. consider list of integers: list<integer> list = new arraylist<integer>(); list.add(5); list.add(6); list.add(7); list.add(1); any educated guess on happens when execute list.remove(1) ? list.remove(new integer(1)) ? can cause nasty bugs. what proper way differentiate between remove(int index) , removes element given index , remove(object o) , removes element reference, when dealing lists of integers? the main point consider here 1 @nikita mentioned - exact parameter matching takes precedence on auto-boxing. java calls method best suits argument. auto boxing , implicit upcasting performed if there's no method can called without casting / auto boxing. the list interface specifies 2 remove methods (please note naming of arguments): remove(object o) remove(int index) that means list.remove(1) removes object @ position 1 , remove(new integer(1)) removes first occurrence of specified element list.

mdt - Microsoft Deployment Toolkit setting SystemAutoLogon registry key when deploying upgraded OS -

i'm trying deploy images via mdt have been upgraded via mdt "standard client upgrade" task sequence. images started win10 v1607 images , updated v1703 , captured. when go deploy captured images, i'll popup on first login c:\ltibootstrap.vbs can't found. digging, discovered after os installed , pc restarts, mdt task sequence continues running the system account . bizarre typically runs built-in administrator account. for reason, though unattend.xml file contains usual autoadminlogon entries, registry key at hklm\software\microsoft\windows nt\currentversion\winlogon\systemautologon is being created , set 1 during deployment. (i discovered comparing registries @ end of deployment.) key not present in captured image. this key not created if deploy image manually updated v1703 (via windows update instead of mdt). any ideas on why unattend.xml ignored or cause systemautologon created , set? i figured out going on. the mdt upgrade task sequence

it likes similar me except top down , bottom-up parsing . can explain ? that indeed fundamental difference. in huffman encoding, codes built bottom repeatedly combining 2 least common entries in list of populations until 2 left. in shannon-fano, population list sorted pop count , repeatedly (recursively) split in 2 - half population in each half, or close 1 can - until 2 entries left in sub-section. huffman has been proven produce (an) optimal prefix encoding whereas shannon-fano (can be) less efficient. shannon-fano, on other hand, arguably bit simpler implement.
