Java Java Objects Meet Objects Creating Classes

Why use System.out.printIn and few other newbie questions..

Hello,

English is not my mother's language so I do not get all what the teacher is saying, therefore I have few questions:

1) What is the differnece between System.out.printIn("text") and console.printf("text") 2) Why use new classes? He's created new class and define there String characterName ="Yoda" --- but couldn't he just write String characterName="Yoda" in a main hmm class/paper/java.file? 3) Sometimes he is using =("text") and sometimes ="text" ae brackets necessary

I'd also like some clarification on the difference between System.out.printIn("text") and console.printf("text")
