What is the difference between the following two lines of code:

System.out.println$("$perimeter$")$; $//$LINE $1$

System.out.println$($perimeter$)$; $//$LINE $2$

LINE $1$ prints out the actual word perimeter and LINE $2$ prints out the value held in the variable: perimeter.

You do not need a semi$-$colon at the end of the two lines.

The lines are identical.

LINE $2$ prints out the actual word perimeter and LINE $1$ prints out the value held in the variable: perimeter.
