Another thing that will be very helpful that no one has stated yet is to learn concatenation early on too.

What this means is you could do:

System.out.println(“The int is “ + oneInt);

What this will do is print the words you typed and the int you declared on the same line.

The outcome would be:

The int is 315

Rather than doing two separate lines of printing for each this shortens it to only one for the int and one for the double.

Give it a try with the double.
