Using the integer 1 in the while statement, or any other looping or conditional
construct for that matter, will result in a compiler error. This is old C Program
syntax, not valid Java.
A, B and C are incorrect because line 1 is valid (Java is case sensitive so While
is a valid class name). Line 8 is also valid because an equation may be placed
in a String operation as shown.
