VI function is the weakest, but also *nix fucked after the most basic Editor.Later VI was enhanced to include many features, which is vim.Then vim joined the graphics interface, Gvim was born.The strongest feature is Gvim, which has many features that Vim does not support, and VI does not supportFor example, do you want to enrich your colors? Blinking the cursor? Set the font independent of the terminal .... These are only gvim supported.Not rigorous said VIM is a collectively representative of

Positive example: iterator while (Iterator.hasnext ()) { String item = Iterator.next (); If (delete element's condition) { Iterator.remove (); } } Counter example: list List.add ("1"); List.add ("2"); for (String item
