(A) Basics (1) Preliminaries A basic model of actual computer systems and the internet Computer terms History of computing Building software: programming languages, compilers, testing Programmers and users (2) Hello, World Simple one method (main) programs Standard output String literals Comments (B) Arithmetic Calculations (1) Numbers Output (print/println) of, literals of, declarations of variables and associated operations of the int and double data types Declaration initialization, final variables (constants) Assignment operators, exchange (swap) algorithm, increment, and decrement Distinction between integer and double arithmetic, divisibility, parity Expressions, precedence, mixed arithmetic and casting (2) Input and Output in Programs Input using Scanner, methods: nextInt, nextDouble; The import statement Formatted output (printf) (C) Other Types: Strings and Logical (1) Strings Output of, literals, declarations, and associated operations of String and their use (concat, length, substring (both forms), indexOf/lastIndexOf (both forms), trim, toUpperCase, toLowerCase, charAt, compareTo, equals) Primitive vs Reference [Object] types: operator vs methods The char data type Input using Scanner, methods: next, nextLine; (2) Logical The boolean type; declaring boolean variables Relational operators Assigning to boolean variables; flags Logical operators The conditional operator Range checking (D) Methods (1) Calling Static Methods Invocation, arguments, and return values Current time (System.currentTimeMillis) Strings to ints/doubles: Integer.parseInt, etc. The Math class and its methods (sqrt, random) Composition (2) Java API Documentation (System, Math, Scanner, String, PrintStream) (3) Static Method Definition Parameter declaration, return type, the return statement Method scope void methods Predicate methods (4) Overloading Methods; signature and prototype (E) Control (1) Branching Compound statements if, if—else Cascading if—else Nested if, if—else (2) Loops Counting loops: for Testing loops: while Loop body logic: selection, counting, accumulation, extremes, adjacency logic Alternate testing loops: do—while (3) Input Loops Headers and counting loops (for) Sentinel (aka "trailer") loops (while) End of data loops (while and hasNext, hasNextInt, hasNextDouble) (4) Nested Loops (F) Arrays (1) Basics: Declaration of array reference variables Creation and initialization of arrays Array access (2) Traversals: Sequential Processing Assignment, selection, counting, accumulation, extremes, adjacency logic Reversals (3) Array-array operations (copying, comparing, arithmetic element-to-element ops) (4) Direct indexed array element access (5) Searching: Sequential Binary (6) Sorting: one or more simple quadratic sorts (selection, bubble, ...) (G) External Files (1) File names vs File objects vs File streams (2) Scanner constructor with File object (3) The importance of close (H) Using the JAVA API Documentation (1) File names vs File objects vs File streams
