java - Intered object with one reference? Does scope apply to interened objects? -


  1. is string object holding value "dog" still considered interned if 0 variable referencing it?

    string 0 = "dog";

  2. how many objects in code? either there's 1 because interned objects ignore scope, or there's 2 because scope still applies.

    string jack = "skellington";  for(//stuff) { string sally = "skellington"; }

string literals interned i.e pool created them. if after decalring 1 string literal, referenced anywhere instance of jvm, picked pool only

1)one object created. not matter if referenced down line or not

2)one object created

see intern method @ http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/string.html
