Question
A class may occasionally be dependent upon itself. In other words, an object of one class engages in communication with an object of the same class. To do this, a method of the class can take an object of the same class as a parameter.
An illustration of this scenario is the concat method of the String class. One String object calls the method, while another String object is supplied as an argument. Here's an illustration:
str2 = str1.concat;
The String object (str1) that executes the method adds its characters to the String (str2) that was supplied as a parameter. As a result, a fresh String object is produced and saved as str3.
