From Chapter 1
Binary system - p 7 - 9
- has two digits: 1 and 0
- the decimal system is base 10, whereas the binary system is base 2
- a single binary digit is called a bit
- there are 2 to the N ways to arrange N bits. (p 9)
- be able to convert binary to decimal and vice versa
Memory - p 12 - 13
Each memory location consists of eight bits or one byte
How many bytes in a kilobyte, megabyte, gigabyte, terabyte? (2 to the 10th, etc....p 13)
Problem solving - p 25
Given a list of problem solving steps, be prepared to give the proper order.
Identifiers and Reserved Words - p 30 - 32
Identifers - Examples: variable names, constant names, class names
Reserved words - identifiers that have a special meaning in a programming language
Know examples of reserved words that we have used: public, int, double
Know identifier naming rules
Know identifier naming rules p 32
Java is a case sensitive language
Comments
// for a single line
/* */ for single or multiple lines
