- 1Binary- Machine/Computer Code
- Essentially a series of 1's and 0's - 2Integrated Development Environment (IDE)- An environment on the computer that allows you to write, run, debug, and convert to machine code
- Like any other application on your computer, except it can facilitate machine code - 3IDE Central Area- Area in the IDE that you use to write code
- 4IDE Console- Area in the IDE that print out useful info for the programmer
- Where you'll see most of your test running and debugging
-Developer tool but it's seen by everyone (backend of the program)
- Don't try to implement the console into the final product - 5Syntax- Rules you must follow to A TEE if you want your program to run correctly
-Each language may have similar syntax, but each have their own unique quirks - 6Print Statements- Simplest instruction you can tell tell the computer to do
- Simply tells the console to "print" something - 7Modulus- Allows us to get the remainder of the divisional operation
- Is in most programming languages
- Represented using ' % ' - 8Strings- Another way of saying "text"
- Anything enclosed within " "
- ie: print ("Game over, 4 was your final score.") - 9Concatenation- Adding strings together
- ie: print("Game over," +4+ "was your final score.") - 10Variable- Something that can store info and can be referenced and/or manipulated
- Each variable has a: Type, name, piece of stored info
- Multiple different types of variables - 11Integer Variable- Variable that can store integer variables
- ONLY WHOLE NUMBERS, NO DECIMALS - 12Boolean Variable- Variable that can store TRUE or FALSE
- 13Float Variable-Variable that can store decimal values
-Can only hold 32 bits (numbers in the value) - 14Double Variable- Variable that can store decimal values
- Can store up to 64 bits (numbers in the value) - 15String Variable- Variable that can store words and sentences
- 16Char Variable- Variable that can store ONE character
- Useful when a programmer wants to read one button press of one character in a string without using an entire string variable
- ie: game controlled by keyboard ( WASD) - 17Blank Variable- Can store info later on
- Can store info given by the user
- Trying to reference a blank variable will result in a NullPointerException (Avoid this) - 18Dual Pointed Variable-Stores things you'll know will have the same value
- Imagine labeling a cardboard bod with two different names
- ie: "Name" and "Channel Name" - 19Naming Variables- Names MUST be one continuous string
-Programmers have their own method of naming variables
- Most programmers name variables according to camelCase - 20camelCase- Don't capitalize the first word, but capitalize every word the follows it
-Easier to find bugs and read the code
- ie: camelCaseVariable
