AP Computer Science 1.5 Classes and Objects

yourself and let's Just go Okay Java syntax police Slightest

mistake and they'll be all over us Cool All right

Good afternoon officer Beautiful day isn't it Uh he wasn't

even looking this way Anyhow we've got a question of

syntax to deal with Which of these snippets will run

without producing an error message Alright well starting a simple

one t one time object is being created properly It

uses the keyword nu to denote that new time object

with the parameters or eight Thirty six and fifteen Essentially

we're holding on to the time of eight Thirty six

and fifteen seconds Invariable t want the next line creates

another time object named t to and gives it the

same value list one the conan option one will work

despite being a little redundant simple to creates a time

object called t one with no value and creates t

to which equals d want no objects have no value

kind like baseball cards and congressmen Everybody likes baseball cards

Yeah despite that this code will actually run albeit pointlessly

so far both option one into will run All right

Looking at our potential answers there was no option for

all of the sniff it's working properly From that we

can reduce their snippet Three won't work but we've got

to check it anyway for the first half of simple

three creates a time object with a null value which

is fine as we just learned But the second half

greets and manager called my seconds right here and attempts

to platform a to string operation on team one essentially

it's trying to take the data in variable t one

and represented as a securing being the t one has

no value there's nothing to represent and you'll get an

error Simple three doesn't work and he is definitely our 00:02:16.495 --> [endTime] answered Jesus
