java - How to Create Object of Interface? -

-

i have field interface

how create object of interface?

look under known implementing classes: customfield

this class looking for

field<t> myfield = new customfield<t>(string name, datatype<t> type);

for list (array) of fields:

arraylist<field<t>> arr = new arraylist<field<t>>(); arr.add(myfield);

if you're not familiar generics, t represents reference type (class) want use

for simple array type (not arraylist) be:

field<t>[] arr = new field<t>()[size]; arr[0] = myfield;

consider using arraylist or other collection, there no reason use plain old array references variables in case.
