Programming Quiz Q1
First Java Midterm

Must be completed during recitation on Feb. 18-20

• You CANNOT use any outside resources
  - This includes the internet, past recitations or programs, textbooks, notes, friends, enemies, classmates, cell phones, tablets, laptops, etc.
• Any and all questions should be directed to your TA and your TA's helper.

1. Create a project called Q1 in Eclipse.
2. Create a class called Q1 in the project Q1 with a main method.
3. Put the code shown below in the main method of Q1.java.
4. Write the rest of your code in the main method, below the code shown.

           // Declare variables
           int int0=0, int1=0, int2=0;
           double real0=0.0, real1=0.0, real2=0.0;
           String string0="", string1="", string2="";
           boolean p = true, q = true, r = false;
   
           try {
   
               // Open input stream
               Scanner scan = new Scanner(new File("data.txt"));
   
               // Read contents
               string0 = scan.nextLine();
               string1 = scan.nextLine();
               string2 = scan.nextLine();
               int0 = scan.nextInt();
               int1 = scan.nextInt();
               int2 = scan.nextInt();
               real0 = scan.nextDouble();
               real1 = scan.nextDouble();
               real2 = scan.nextDouble();
               p = scan.nextBoolean();
               q = scan.nextBoolean();
               r = scan.nextBoolean();
   
               // Close input stream
               scan.close();
   
           } catch (IOException e) {
               System.out.println("Cannot read file: data.txt");
               System.exit(0);
           }
   

5. Use Eclipse to add the imports needed for the above code.
6. Copy the data file into data.txt into the Q1 project (~/workspace/Q1).
7. Follow the instructions from the TA to complete the programming quiz.
8. Make sure your Q1.java compiles and produces exactly 10 lines of output.
9. Submit your Q1.java to the RamCT dropbox for this programming quiz.
10. WARNING: Only one submission is allowed!

A) Print an expression that adds int0, int1, and int2, then multiplies the result by 321. (10 points)

B) Print an expression that subtracts real2 from real1, then divides the result by 5.3. (10 points)

C) Print the result of int2 multiplied by real1 squared with exactly 6 digits after the decimal. (10 points)

D) Print an expression with the concatenation of "Java programming is " and the 14th, 12th, 15th, and 13th character of string0, not separated by any spaces. (10 points)

E) Print the fourth characters of string0, string1, and string2, separated by commas. (10 points)

F) Print the boolean that is returned from a comparison of the contents of string0 and string1 using the appropriate String method. (10 points)

G) Print the result of the boolean expression (p∧q)∨(q∨¬r). (10 points)

H) Write an if/else statement as follows (10 points):

• Print "8 characters or fewer." if the length of string1 is less than 9.
• Otherwise print "9 characters or more." if the length of string1 is 9 or more.

I) Write a conditional statement as follows (10 points):

• Print (real1 + 2.334), if real1 < 9.87.
• Print (real1 / 0.135), if real1 > 12.3 and real1 ≤ 21.99.
• Otherwise print (real1 * real1 / 5.221).

J)Write a switch statement as follows (10 points):

• The switch statement should check the value of string1.
• If string1 equals "Guanajuato" or "Fort Collins", use System.out.println() to print the string "North America".
• If string1 equals "Santiago" or "Lima", use System.out.println() to print the string "South America".
• Otherwise using System.out.println() to print the string "Unknown City".
