• Two most important methods
    void setup() method runs once in the begining
    void draw() runs multiple times (once for each frame)
  • Each executable line of code is called statement. It ends with ;
    Ex: size(400, 400);
  • Single line comments start with // and they are not executed
    Ex: //this is comment. Has no effect on program
  • Multi line comments start with /* and end with */
    Ex: /* this is a multiline comment.
    Has no effect on program */
