Use break to Exit a Loop
It is possible to force an immediate exit from a loop, bypassing any remaining code in the
body of the loop and the loop's conditional test, by using the
break
statement. When a
break
statement is encountered inside a loop, the loop is terminated and program control
resumes at the next statement following the loop. Here is a simple example:
This program generates the following output:
As you can see, although the
for
loop is designed to run from 0 to
num
(which in this case
is 100), the
break
statement causes it to terminate early, when
i
squared is greater than or
equal to
num
.
The
break
statement can be used with any of Java's loops, including intentionally infin-
ite loops. For example, the following program simply reads input until the user types the
letter q:
