In class we discussed Model 1 and Model 2 (MVC) architecture for web applications.   Describe the flow of a web request in the Model 1 architecture.   Describe the flow of a web request in the Model 2 architecture.   Name two benefits of Model 2 over Model 1.    

List the four scopes that EL expressions search when resolving a name, in the order in which they are checked.

Shared Instructions Indicate the result of the snippet of code, assuming that it is in a main method of a class. More specifically, you must indicate one of the following: the output of the code, if the code compiles and runs without errors which statement(s) don’t compile (line #s, first line is #1) and why, if the code doesn’t compile when put in a main method the type of runtime error and the statement that caused it (line #, first line is #1) if the code compiles but doesn’t run properly Shared Code public class W { // In W.java public String toString() { return “W”; } public String sW() { return “1”; } } public class X extends W { // In X.java public String toString() { return “X”; } public String sX() { return “2”; } } public class Y extends X {} // In Y.java public class Z extends W {} // In Z.java Unique Snippet Y y = new W(); System.out.print(y.toString());

Write a compareTo method for the Puma class that uses two instance variables to determine order: name (String) and maxSpeed (int). The ordering of Puma established by this class is: Order first by maxSpeed, in ascending order. Order second by name, in ascending lexicographical order (String’s compareTo). If both variables are the same between the instances, the pumas are equal. You do not have to add the code for the instance variables.
