if method returns object particular array index, , object modified, object modified locally or object in array modified? is there way force each case? the object in array modified. works way because, although java pass value, it's passing value of object reference . in end array has copy of reference , whatever gets result has copy of reference. when modify object itself, you're modifying thing both "point" to. both see change. the way make not true make copy of element before return it. alternatively, if make object immutable, don't have worry these details because can't change object in first place.

i've heard absolutely positioned element positions relative first non-statically-positioned ancestor. there more holistic reason this? or arbitrary choice made, wouldn't true static elements. i guess i'm wondering if there's unified theory of css, speak, i.e. 1 that's perhaps complicated, less complex. 1 outlines behavior of position , static , absolute in such way interaction comes out of natural consequence. i can't find explicit reference rule in css spec; might help. simply because forcing people position elements relative parent element needless limitation. if want position element relative <body> ? if want position element relative specific ancestor? well, set position: relative on target parent. without this, i'd need use js. of course, don't think best way implemented. if wrote spec self, i'd make it: position: absolute(selector); but of course, don't write spec.

this separate whether app has requested editor action: editor action displayed replacement enter key, it's possible input method offer both alternatives. the simple answer is, of course, "when it's possible enter newline". when textview in single-line mode , it's not possible enter newline if keyboard shows key: found in this answer , android treats key editor action , substitutes zero-width space newlines added textview . how can input method tell whether newlines respected, or otherwise whether it's appropriate show enter key (as alternative specified editor action)? your best bet check editorinfo object returned using getcurrentinputeditorinfo() , take best guess if showing enter key apt or not.

let's have program puts email addresses database email attribute primary key. if have duplicate email address, deal in 2 ways. 1) run "select email table" query. if email in there, don't add it. 2) don't check if email in table. catch(sqlexception e), don't print stack trace, skip on it. way, if i'm inserting duplicate ignores it. granted method 1, i'm executing simple select query (no joins or fancy) performance isn't huge issue. if wanted optimize performance, method 2 viable, safe way of doing this? instead of running "select ..." every time, add it. are there safety issues skipping on exception? java example (with jdbc): try { string sql = "insert emails values(?)"; preparedstatement pstmt = conn.preparestatement(sql); pstmt.setstring(1, email); pstmt.execute(); return true; } catch(sqlexception e) { // e.printstacktrace(); // skip; don't print out error return false; } ...
