The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Textbook Question

Chapter 7, Problem 8PP

Write a program that will read a line of text and output a list of all the letters that occur in the text together with the number of times each letter occurs in the line. End the line with a period that serves as a sentinel value. The letters should be listed in the following order: the most frequently occurring letter, the next most frequently occurring letter, and so forth. Use two arrays, one to hold integers and one to hold letters. You may assume that the input uses all lowercase letters. For example, the input

do be do bo.

should produce output similar to the following:

o	3
d	2
b	2
e	1

Your program will need to sort the arrays according to the values in the integer array. This will require that you modify the function sort given in Display 7.12. You cannot use sort to solve this problem without changing the function. If this is a class assignment, ask your instructor if input/output should be done with the keyboard and screen or if it should be done with files. If it is to be done with files, ask your instructor for instructions on file names.

7. See the code below and solve the following. public class Test { public static void main(String[] args) { int result = 0; } result = fn(2,3); System.out.println("The result is: + result); // fn(x, 1) = x // fn(x, y) = fn(x, y-1) + 2, when y>1 public static int fn(int x, int y) { if (x <= 1) return x; else return fn(x, y-1) + 2; } } 7-1. This program has a bug that leads to infinite recursion. Modify fn(int x, int y) method to fix the problem. (2 point) 7-2. Manually trace the recursive call, fn(2,3) and show the output (step by step). (2 point) 7-3. Can you identify the Base Case in recursive method fn(int x, int y)? (1 point)

6. See the code below and solve the following. import java.io.*; public class DataStream { } public static void main(String[] args) } DataOutputStream output = new DataOutputStream(new FileOutputStream("temp.dat")); output.writeUTF("Book1"); output.writeInt(85); output.writeUTF("Book2"); output.writeInt(125); output.writeUTF("Book3"); output.writeInt(70); output.close(); // ToDo: Read all data from temp.dat and print the data to the standard output (monitor) 6-1. This program has a compile error, and the message is “Unhandled exception type FileNotFoundException". How do you fix this error? (1 point) 6-2. Is FileNotFoundException a checked exception or an unchecked exception? (1 point) 6-3. What is the difference between checked exception and unchecked exception? (1 point) 6-4. Please complete the above program by reading all data from temp.dat and print the data to the standard output (monitor) by using System.out.print, System.out.println or System.out.printf method. (2 points)

Write a program that reads a list of integers from input and determines if the list is a palindrome (values are identical from first to last and last to first). The input begins with an integer indicating the length of the list that follows. Assume the list will contain a maximum of 20 integers. Output "yes" if the list is a palindrome and "no" otherwise. The output ends with a newline. Hints: - use a for loop to populate the array based on the specified size (the first number entered) - use a for loop to check first value with last value, second value with second from end, etc. - if the values do not match, set a Boolean variable to flag which statement to output (yes or no) Ex: If the input is (remember to include spaces between the numbers): 6 1 5 9 9 5 1 the output is: yes Ex: If the input is: 5 1 2 3 4 5 the output is: C++ coding
