Chapter 8, Problem 7PP
Modify the Student class in Listing 8.2 so that it implements the comparable interface. Define the compareTo method to order Student objects based on the value in studentNumber. In a main method create an array of at least five Student objects, sort them using Arrays.sort, and output the students. They should be listed by ascending student number Next, modify the compareTo method so it orders Student objects based on the lexicographic ordering of the name variable. Without modification to the main method, the

If a class implements the Comparable interface, it is easy to swap in/out different strategies for comparing objects of that class. For example, if our Shapes implement Comparable and provide a compareTo() that compares areas, we can provide another compareTo() override for those shapes that compares perimeter.

- Implement the Solver class. In doing so, you are allowed to define other classes to help you (as well as use “built-in” Java classes or the book’s classes). The point of the solver class is the solve method which takes a board/puzzle configuration represented as a 2D array of booleans and returns a char array containing a minimal sequence of moves that will lead to the solved board (all the cells around the edges being filled). The board configuration is passed in as a 5-by-5 boolean array of Booleans with exactly 16 true cells (filled) and 9 false cells (empty). The solve method then returns an array of characters representing a minimal sequence of moves that solves the puzzle. In other words, if the characters from the returned array are used in order as input to the move method on the Board object representing the initial configuration, the resulting board configuration represents the solved board. Furthermore, the solution must be minimal in the sense that there are no solutions…arrow_forwardImplement the Solver class.
