Think as Computer Scientist
Problem-Solving
the ability to formulate problems, think
creatively about solutions, and express a
solution clearly and accurately
The process of learning to program is an
excellent opportunity to practice
problem-solving skills.

Programming languages
High level language
Java, Python, C or C++, and Perl
Low level languages
machine language or assembly language
Loosely-speaking, computers can only run
programs written in low-level languages
Translate from high level to low-level =
compile or interpret
4
advantages
High level languages
It is much easier to program in a highlevel language
less time, shorter and easier to read , most
likely to be correct
Portable
can run on different kinds of computers with
few or no modifications

Java history
Java was created in 1991 by James
Gosling in Sun Microsystems
Initially called Oak
in honor of the tree outside Gosling's window
Its name was changed to Java
because there was already a language called
Oak.
Sun Microsystems released the first
public implementation as Java 1.0 in 1995
Java syntax is similar to C and C++.

Java Motivation
The need for platform independent
language
To be embedded in various consumer
electronic products
like toasters and refrigerators
Platform independent?!
Hardware
Operating System
