The For Statement
Completion requirements
The 'for' loop is more compact than the 'while' and 'do' loops and automatically updates the loop counter at the end of each iteration. Both 'for' and 'while' loops are designed for different situations. You'll learn more about when to use each later.
12. Omitting the change
Answer:
Yes.
Omitting the change
Syntactically you can omit the change part. This means that if the Java compiler sees:
for ( count = 0; count < 25; )
it will not complain. It is now your responsibility to put statements that make a change somewhere into the loop body. For example:
for ( count = 0; count < 25; )
{
System.out.println("count is: " + count );
count = count + 1;
}
would work fine. (Although in this case it would be far better to do the change in the for.)

Can a
forstatement be used to implement a sentinel controlled loop?
