Hi,

int is a data type in Java. It allows you to store whole numbers like -7, 0 or 46; but not 5.5 because that's not a whole number.

For the lesson you only need to put any whole number (as long as it's not too big or too small) between the parenthisis of System.out.println(); The programm will then print this number to the console.

There are more data types that will be covered in the course. For now you also don't have to worry about classes, they will be covered later.
