10.5.
for
The
for
statement comes in two forms: a basic and an enhanced form.
The basic form is the more general and powerful of the two.
10.5.1. Basic
for
Statement
You use the basic
for
statement to loop over a range of values from be-
ginning to end. It looks like this:
for (
initialization-expression
;
loop-expression
;
update-expression
)
statement
The
initialization-expression
allows you to declare and/or initialize loop
variables, and is executed only once. Then the
loop-expression
of
boolean
or
Boolean
typeis evaluated and if it is
true
the statement in the body of
the loop is executed. After executing the loop body, the
update-expression
is evaluated, usually to update the values of the loop variables, and then
the
loop-expression
is reevaluated. This cycle repeats until the
loop-ex-
pression
is found to be
false
. This is roughly equivalent to
{
initialization-expression
;
while (
loop-expression
) {
statement
update-expression
;
}
}
