In some circumstances, a class is reliant on itself. That is, one class's object interacts with another class's object. To accomplish this, a method of the class may accept an object of the same class as a parameter.The String class's concat function is an example of this situation. The method is called by one String object and receives another String object as an argument. Here's an illustration:str3 is equal to str1.concat(str2);The method's String object (str1) appends its characters to those of the String supplied as a parameter (str2). As a consequence, a new String object is returned and saved as str3. Create Java code to implement the conditions given.
