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 Foo {    public String method1() { return “foo 1”; }    public String method2() { return “foo 2”; }}public class Bar extends Foo {    public String method3() { return “bar 3”; }}public class Baz extends Bar {    public String method1() { return “baz 1”; }}public class Mumble extends Foo {    public String method2() { return “mumble 2”; }} Unique Snippet Mumble m = new Mumble();Foo f = (Foo) m;System.out.print(f.method1() + ((Bar) f).method2());

Indicate the Big-O notation and growth rate for the following algorithms: selection sort, insertion sort, merge sort. Use this template for your answer (please type fully – you cannot copy): Selection Sort: [Big-O notation], [growth rate] Insertion Sort: [Big-O notation], [growth rate] Merge Sort: [Big-O notation], [growth rate]

Write code for a public static method named numLinesWithPrefix. The method receives a File and a String and returns an int: the number of lines in the file that start with the input String. If there is an error reading the file, the method should propagate an IOException. You must use exception handling code; you cannot use File methods or Scanner hasX methods directly. Make sure to close every object that should be closed before returning. Don’t write import statements or a class header. As part of error handling, use the Scanner’s NoSuchElementException. HINT: use String’s instance method startsWith(String prefix).

[2pts EXTRA CREDIT] State if O(log(n2)) is equal to O(log(n)). If it is, explain why. If not, which is more efficient? (1-2 sentences)

Upcasting in Java is only sometimes valid, depending on what the object is being cast to.

State the Big-O Notation and growth rate of the following code: public static void tryThis(int n) {    int k = 8;   for (int i = 0; i

You are given an unsorted array below. Perform the first three iterations of the Selection Sort algorithm. Array:    9    7    8    2    1    4    6 Use this template for your answer (please type fully – you cannot copy): Iteration 1: [array after first iteration – 7 numbers space-separated] Iteration 2: [array after second iteration – 7 numbers space-separated] Iteration 3: [array after third iteration – 7 numbers space-separated]
