Break
While loops will usually stop running when the condition at the top evaluates
to false
.
This can be bypassed by using the break
statement.
void main() {
int x = 5;
while (x > 0) {
if (x == 2) {
break;
}
x--;
}
System.out.println(
"Final value of x is " + x
);
}
If a break
is reached, the code in the loop stops running immediately.
The condition of the loop is not checked again.
This can be useful in a variety of situations, but notably it is the only way to exit from an otherwise endless loop.
void main() {
while (true) {
System.out.println(
"The people started singing it not knowing what it was"
);
// Will immediately leave the loop
break;
}
}
