Lab must be completed and
reviewed by Peer Instructor on Fri, Jan 16 during lab class and no later than
the first 10 minutes of lab class on Tues, Jan 20.
Description
In this lab you'll create
a new Java program that will generate the output specified below.
Task 1 - Prepare to create
your own 1st Java program.
- You may want to look
at the Java programs from Lab 1 to remind you of the structure required. In
fact, you can even copy a program, rename it, and use it to write this program.
Task 2 - Create the class
and method headers
- The class name should
be lab2 (so it will have to be saved in a file named what?)
- Since there will be only
one method, what should the name be?
- Make sure there's a comment
above the method describing what it does.
Task 3 - Build the comment
(banner) at the top of the program.
- Remember to include your
name, the section and course number, the assignment (lab2), and a description
of what the program will do.
- Use the // or /* symbols
to denote your comment.
Task 4 - Create some
variable declarations.
In your program, declare
7 variables:
- three int
variables (larry, moe &
curly) - initial values should
be set to 2, 4, & 6,
- one char
variable (letter) - initial
value should be set to 'X',
- one boolean
variable (test) - initial value
should be set to true
- two double
variables (abbott & costello)
- initial values should be set to
1.5 & 2.63
Task 5 - Create the print
and assignment statements necessary to complete the lab.
- First, print some header
lines. They should look like this: (use tabs in front of your name)
Lab 2 Your
name
---- ---------
- Use the println method
from the System.out object to output a string concatenated with the value
of each of the 7 variables.
Example: System.out.println("larry's
value is " + larry);
would produce the output:
larry's value is 2
- Output a blank line.
- Output the sum of larry,
moe and curly on a line, along with a descriptive label.
- Output another blank
line.
- Output the sum of abbott
and costello on a line, along with a descriptive label.
- Output another blank
line.
- Output the concatenation
of all 7 of the variable's values on one line. No spaces necessary.
Example (these are not the correct values): 3423false21.02.0
Task 6 - Compile and
execute the program.
Completion Requirements
Once you've completed the
lab, you should show the Peer Instructor that you have completed:
-- Run the lab2 program,
-- the PI will compare the specified output to your output.
-- then use PFE to show the lab2.java file to the PI, your comments and code
structure will be checked.
