static factory methods common naming conventions
This list is far from exhaustive:
from
A type-conversion method that takes a single parameter and returns a corresponding instance of this type.
Date d = Date.from(instant);
of
An aggregation method
that takes multiple parameters and returns an instance of this type that incorporates them.
Set\<Rank\> faceCards = EnumSet.of(JACK, QUEEN, KING);
valueOf
A more verbose alternative to from
and of
BigInteger prime = BigInteger.valueOf(Integer.MAX_VALUE);
instance
or getInstance
Returns an instance that is described by its parameters (if any) but cannot be said to have the same value.
StackWalker luke = StackWalker.getInstance(options);
create
or newInstance
Like instance
or getInstance
, except that the method guarantees that each call returns a new instance.
Object newArray = Array.newInstance(classObject, arrayLen);
get
Type
Like getInstance
, but used if the factory method is in a different class. Type is the type of object returned by the factory method.
FileStore fs = Files.getFileStore(path);
new
Type
Line newInstance
, but used if the factory method is in a different class. Type is the type of object returned by the factory method.
BufferedReader br = Files.newBufferedReader(path);
type
A concise alternative to get
Type and new
Type.
