Big O notation for java's collections
The book Java Generics and Collections has this information (pages: 188, 211, 222, 240).
List implementations:
get add contains next remove(0) iterator.remove
ArrayList O(1) O(1) O(n) O(1) O(n) O(n)
LinkedList O(n) O(1) O(n) O(1) O(1) O(1)
In the below keyboard shortcuts, I use the capital letters for reading clarity but this does not imply shift, if shift is needed, I will say shift. So ⌘ + D does not mean hold shift. ⌘ + Shift + D does of course.
| Function | Shortcut |
|---|---|
| New Tab | ⌘ + T |
| Close Tab or Window | ⌘ + W (same as many mac apps) |
| Go to Tab | ⌘ + Number Key (ie: ⌘2 is 2nd tab) |
| Go to Split Pane by Direction | ⌘ + Option + Arrow Key |
