Cómo imprimir para consolar en Java
//This is for printing in columns
System.out.println("Hello World!");
//This is for printing in rows
System.out.print("Hello World");
//When im using the double slash its to comment, also remember that you dont need to type Hello World! you can type everything you want
//By the way, you can also do:
int a = 1;
System.out.println(a);
//the result of this is "1" because a is equal to 1 so the programm whill get the data stored in "a" and print it, remember that you can also use "print" instead of "println" it works whit "vairables" too! (oh, the: int a = 1; is a variable)
