00:00

Sorry Then here's your shmoop du jour brought to you

00:06

by primitive data types Watch out they bite But which

00:12

of the following commands creates an object Recall the difference

00:20

between primitives and objects Objects can contain many data fields

00:24

such as variables and methods Primitives can only contain one

00:28

specific value Remember that we have eight primitive types in

00:33

char double bite short long float and billions primitives air

00:38

like the less evolved less intelligent versions of objects I've

00:42

been the congress lately All right Looking at our potential

00:46

answers we can see that some of them create new

00:49

it's question asked for objects so we can eliminate choices

00:53

and now we can see the choices Dian ear incorrect

00:56

de specifies the code that you need to initialize a

01:00

string but it's not the complete code for creating one

01:03

gone is missing The parentheses at the end that specify

01:07

what tax to put in the string is also missing

01:10

a semicolon Well that leaves us just with choice Seas

01:13

are correct answers Looking closer we can see that it

01:17

correctly declares a new string object and fills it with

01:20

a value Yeah next time we'll look at the epic 00:01:23.866 --> [endTime] uprising of the evolving mistreated primitives Ah
