The Scanner class helps to create the object for Scanner for reading the input strings from console and also inputs are delimited by whitespace characters.

The syntax to create an object for Scanner class using System.in is given below:

Scanner objName = new Scanner(System.in);

The syntax to create an object for Scanner class using input file is given below:

Although color television was not added to the industry standard until 1956, CBS had been broadcasting selected special events in color as early as 1950. Question 1 options: True False Two key factors in creating the Network Era of American television were the FCC licensing freeze and ______________. Question 4 options: The Quiz Show Scandals Habitual Viewing Operation Frontal Lobes Drop-In Viewing Least Objectionable Programming was designed to embrace the public service-oriented vision of using television to elevate mass culture and enrich viewers.

Question 9 options: True False

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)
