Dear all, I submit you something I find quite intersting, about String, toString, ...
As you may expect, the result is something of the following form: AAAZ@1ea2dfe. Indeed, System.out.println invokes automatically the toString() method inherited from Object on instance Z, which prints out the name of the object's class + some identifying value - typically its reference value, separated by iy the at symbol. What's happening now with this code?
Output: Z AAAZ1ea2dfe Waht is worth noting here is that "Z" is printed out on its own line before the toString() method would be happened to AAA on its own line also. The same logic applies in the following case, when overriding the toString method:
output: ### AAAZ Hoe this can help, Cyril.
