Definitions

• Java Name of a programming language, in fact the
  programming language we will use this semester.
• Programming language A language that we use to
  communicate instructions to the computer. The
  first programming language was FORTRAN (1957).
  How did we communicate with computers before then?

4
Programming Languages

• Iterative/Procedural
• BASIC, C, Pascal
• Functional
• LISP, Scheme, ML
• Object-Oriented
• Simula, Java
• Declarative
• Prolog
• Scripting
• JavaScript, VBScript, PHP

5
Question

• Are HTML and XML programming languages?
• NO!!!!
• So, what makes a language we use in the computer
  a programming language?

6
Three key features

• Sequencing
• Selection
• Repetition
• We will see how these three ideas are implemented
  in Java as the semester progresses.

7
Computing environment

• UB computing account (UBUnix)
• workstations compute servers file
  server e-mail server
• _at_buffalo.edu
• CSE computing account
• Baldy 21
• compute server file server e-mail server
• _at_cse.buffalo.edu

Definitions

• Yeager All CSE 115 students have an account on
  yeager.cse.buffalo.edu. If you are not
  physically in the lab, you will log into yeager
  using.
• PuTTy A secure telnet client that allows you to
  connect to other systems from your home machine.
  If you want to work on your CSE 115 assignments,
  you would log into the system named
  yeager.cse.buffalo.edu and use the same username
  and password as you would in the labs.

More Definitions

• UNIX The operating system that is run on the
  systems in the CSE department. It was created in
  1969 at Bell Labs. Other noteable 1969 creations
  the ARPANET. The ARPANET is the precursor to
  the ???
• operating system Software that is directly
  responsible for coordinating all activities of
  both the hardware and the software on the
  computer, and facilitating communication between
  the two.

11
Still More Definitions

• coldplay Another compute server in the CSE
  department. Eclipse is installed on this
  machine. You will be using coldplay during your
  recitation/lab time.
• Eclipse The IDE (Integrated Development
  Environment) that we will be using this semester
  to help us create our programs.

12
Even More Definitions

• Hadar the name of the file server for all the
  CSE machines we have talked about so far (yeager,
  coldplay, everest). Because all three of those
  systems are file-served by the same machine, this
  means that the same files are accessible no
  matter which of the three you are logged in to.
  You should not log into hadar remotely or from
  within the lab unless you are simply going to
  change your password. Passwords for your CSE
  accounts can only be changed on hadar.

13
Geez there are a lot of Definitions

• fileZilla A program that allows you to transfer
  files from your home machine to one of the CSE
  machines, and vice versa. When you are
  transferring files, you will be transferring them
  to the system that is file served by hadar.

14
Last Definition!

• Baldy 21 The place you need to go to for your
  recitations. Please make sure to do the work
  that needs to be completed before going to lab.
  It is also an extremely good idea to read over
  the lab assignment before going to your lab
  session and even perhaps printing out the
  assignment to have with you and take notes on
  during your lab time.
