A
continue
statement with label

attempts to transfer control to the enclosing
labeled statement (§
14.7
) that has the same
Identifier
as its label; that statement, which is
called the
continue target
, then immediately ends the current iteration and begins a new
one.
To be precise, a
continue
statement with label

always completes abruptly, the reas-

The continue target must be a

A
continue
statement must refer to a label within the immediately enclosing method, con-
structor, or initializer. There are no non-local jumps. If no labeled statement with
Identifier
as its label in the immediately enclosing method, constructor, or initializer contains the
con-
tinue
statement, a compile-time error occurs.
It can be seen, then, that a
continue
statement always completes abruptly.
