api java 5 more: should i relapse an array collection?

in idea , i face identical doubt nearing . (yes, i know, ;-) ).

for functions returning collection (which rudimentary ), i always move (in jdk1.4.2) returning an array instead general list, because:

• it enforces returning form (myobject[] instead list objects, many some-more type-safe stationary -- 'compilation' -- level)


• it suggests 'read-only' impression returned collection (it some-more difficult supplement an component collection, even nonetheless severe 'read-only' keyword c#). same observant 'immutable' given references inside array still modified...

of course, i always create returned array (i arrangement any 'internal' array)

now, jdk5 more, i list<myobject> i wish to.

what good reasons selecting relapse myobject[] instead list collection<myobject> coding java5 ?

bonus, collection<myobject> used, illusory to:

• enforce read-only charge returned collection ? (no add() remove() possible)


• enforce an permanent aspect returned collection ? (even references collection modified)

ps: definitely have one.
