The majority of the course is based on exams (50\% between the 3 midterms and the
|
|
final), and assignments (an additional 25\%). The final will include a practical,
|
|
and will be 50/50 code and text quetions. The exams will be mostly code, with
|
|
30\% being multiple choice questions.

\section{Java Eccentricities}
|
|
|
|
Java's a high level language. This gets compiled into bytecode, which are files
|
|
that have a \verb|.class| extension. This code is then executed in a Java virtual
|
|
machine. Because all Java code is written for a VM, it can run on any platform
|
|
\dots theoretically.
|
|
|
|
Java requires a lot of scaffolding to write any program. Every program must be
|
|
within a class, and you must have a \verb|main| function within that class.
|
|
All methods written in the first unit of this course will be \verb|static|.
|
|
Additionally, all classes and methods will be public for the first unit. The
|
|
name of the file needs to be character-identical to the name of the file, and
|
|
they are conventionally PascalCase.
|
|
|
|
Strings are always double-quoted. Single-quotes are for \verb|char|s. Variables
|
|
must be declared with a type, but you do not have to initialize it. Java has two
|
|
main groups of types, primitives and references. Primitives are anything that
|
|
can translate to bits (byte, short, int, etc). Anything else is a reference type.
|
|
Any unlabeled number is assumed to be either an int or a double, depending on
|
|
whether there's a decimal or not. You can force a long or float by having the
|
|
suffix \verb|l| or \verb|f|, respectively. Every statement has to have a semicolon.
|
|
|
|
|
|
Strings and ints can be concatenated without casting (at least in the instane of
|
|
\verb|System.out.print(ln)|.
|
|
|
|
\section{Math}
|
|
|
|
There is no unique function for integer division. Dividing two integers will do that.
|
|
Powers are done through \verb|Math.pow(x, y)| to get $x^y$. Things are always
|
|
promoted to the most precise type.
|
|
|
|
\section{Return}
|
|
|
|
Return types have to be declared. Voids do not need a return call, but must be
|
|
argument-less if used.
|
|
|
|
\section{Boolean}
|
|
|
|
Booleans are the same as in C++, as are comparators. Conditionals are \verb|if|,
|
|
\verb|else if|, and \verb|else|.
