This Notes is according to the udacity free course : Intro to Java Programming Lesson 1 : Introduction-5(Algorithms) Key Word : pseudocode Algorithms just like a doing things protocol+condition. Without protocol+condition, you can not make choice or do the decision. So if you want to buy car, you know the car speed and you don't consider the car price or the car condition, so it is your thought, it is the algorithm you buy a car. For computer, we give them the program ===>for them to do algorithm, but now we try to write done in Pseudocode. Pseudocode write in "spoken language" which help us to understand the problem so we can translate them into computer language ==>JAVA Code.org maybe it could help you have fun from learning code
