How many String objects created

[allison craig]

String str = new String("zyx");

Yeah, yeah, I know everybody knows this.

Is it two, one for the 'new String' and the other "zyx"?
Is there a way check the actual number of Strings created?

Just as you guessed, 2 String objects. A String literal "zyx" and a String object. Latter is eligible for GC and the former isn't.

Method void main(java.lang.String[])
   0 new #2 <Class java.lang.String>
   3 dup
   4 ldc #3 <String "zyx">
   6 invokespecial #4 <Method java.lang.String(java.lang.String)>
   9 astore_1
  10 return

Thanks Vin. I'm going to pretend I can read opcodes.
