string and string buffers?

[senthil sen]

string sq="String object1"+String object2"
here there are 2 objects created
stringbuffer sq="String object1"+String object2"
well since string buffers are growable these two string objects are placed in the string buffer object.
what happens in the string object above??

Here, there is 1 object created, containing the String "String object1Stringobject2" (ignoring the typo).

This fails to compile as String and StringBuffer are incompatible types.

if
String s1= "Stringobj1"+Stringobj2";
does s1 carry \both the string object?
will it make stringobj1 and stingobj2 as one object??explain??
And why is that stringbuffer is not compatible to string object???explain
