Why printf instead of println?

I've noticed certain Java textbook authors (Deitel) use printf also, but my college professors want us to use println. Since someone made the design choice to use printf in this tutorial I was hoping to hear the rationale. Thanks!

The printf method can be incredibly useful when displaying multiple variables in one line -- which would be tedious using string concatenation.

In prinf you do not have to write the float and strings and decimals and you can use placeholders: %s, %d, %f and assign it in the end.

Neither do you need to have to write the float and strings and decimals in the println when concatenating! or am I missing something here?
