Syntax Quiz 2, Step 8

Assignment:

Write a variable declaration for a local variable named localVar of a type suitable to hold a floating-point number.

My solution:

 double localVar; 

Common mistakes:

Omitting or mis-placing the type name.

Every variable, whether instance, parameter, or local, must be declared with a specific type, using the syntax
type-name var-name

Omitting the semicolon.

Local variables are declared in declaration statements, which like all other statements must end in a semicolon.

Putting a private or public in front.

The modifiers "private" and "public" don't make sense for local variables (we'll see why later in the semester).
