in Java please define the following parent class and its child class

please comment thought process

2 PRINTWRITER CLASS Java provides output facilities through various classes. You are likely very familiar with System.out by now (using its output methods print/println/printf). Inspecting the system class you will see that out, a static field, is an instance of the PrintStream class. This endows it with many methods such as print/println/printf. To write to a file, we will use the java.io.PrintHriter class. It is quite similar to System.out in that Printwriters have print/printin/printf methods. When constructing a Printwriter, the constructor determines the destination of output. Should a File be passed in, all output is directed the file. PrintWriter pwl -new PrintWriter (System.out); Printwriter pw2 new Printwriter("myfile.txt") Note: PrintWriters do not always push their output to the destination immediately. When printing to a file, call close() to ensure all output is pushed to the file When printing to the screen, one may need to call flush ) to get text to appear (especially when you've written part of a line but not the newline character). In subclasses, flush ) can be added to print/println to do this. Make sure NOT to call close () on a PrintWriter that is writing to the screen: this will close System.out and prevent ALL further output from being printed to the screen. 2 PRINTWRITER CLASS Java provides output facilities through various classes.
