1. First JVM has to compute "A"+new C(). At this point nothing is printed yet, computation is going in memory. 2. new C() calls toString() method of C class 3. Within toString() method "B" is printed (it is the first thing that is getting printed!!!) 4. toString() returns "C". "A"+"C" is computed 5. First println is executed, printing "AC". Shura
Because of the concatenation of the new C object with the String "A", the C object will automatically have the toString() method called on it in order to convert it to a String format so that it can be output. Corey
do you mean that no matter when and where i creat an object using the ''new'' keyword will cause the toString() method of that object to be executed automaticly? thanks!

No! The toString() method is not called when the object is created, but any time the object needs to be displayed as a String. The purpose of the "toString" method is to display the object in a String. Corey
