What's the fastest way to normalize a Time object?
Joe Sam Shirah Of the two recommended ways when using a Calendar( see How do I create a java.sql.Time object? ), in my tests, this code ( where c is a Calendar and t is a Time ):
c.set( Calendar.YEAR, 1970 ); c.set( Calendar.MONTH, Calendar.JANUARY ); c.set( Calendar.DATE, 1 ); c.set( Calendar.MILLISECOND, 0 ); t = new java.sql.Time( c.getTime().getTime() );was always at least twice as fast as:
t = java.sql.Time.valueOf( c.get(Calendar.HOUR_OF_DAY) + ":" + c.get(Calendar.MINUTE) + ":" + c.get(Calendar.SECOND) );When the argument sent to valueOf() was hardcoded ( i.e. valueOf( "13:50:10" ), the time difference over 1000 iterations was negligible.
