A subform can contain another subform.

Repeat Practice Program 1, but instead write a method insertionSort that performs an insertion sort, as described in Programming Project 4 of Chapter 7.

As with the previous project, an easy way to develop the program is to start with the insertion sort code for an array, Chapter 7 Programming Project 4. Note, however, that the list code, unlike that for the array, does not need a helper method to move the elements when a new element is added to the temporary list; the ArrayList class has a method, add(int, T), that does it for you.

Repeat the previous programming project, but read the input data from a file and send the output to another file. If you have covered binary files, use binary files; otherwise, use text files. Read the file names from the user.

This Project can be done in many different ways. The solution shown here reads records from the user-specified input file into a list, then sorts the elements by the pets’ weights using bubble sort, and also sends the output to a file.
