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

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

specific value Remember that we have eight primitive types in

char double bite short long float and billions primitives air

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
