It follows that the return statement must be the last statement executed in a
function, as the rest of the code will never be reached.
Note that there is a significant difference between a statement being the last line
of code that is executed in a method and the last line of code in the method itself.
In the example above, the line return true; is clearly not the last line of code
that is written in the function, but it may be the last line that is executed (if the
condition involving date is true). Such a statement explicitly interrupts the flow
of control in the method. There are two other such explicit control-flow
statements, which are used in conjunction with loops and switch statements.
The break Statement
The typical use of a break statement has the following simple syntax:
break;
It is used to "break" out of the innermost switch, for, while, or dowhile
statement body. When it is executed, a break statement causes the flow of
control to jump to the next line after the loop or switch to the body containing
the break.
The break statement can also be used in a labeled form to jump out of an
outernested loop or switch statement. In this case, it has the syntax
break label;
where label is a Java identifier that is used to label a loop or switch statement.
Such a label can only appear at the beginning of the declaration of a loop. There
are no other kinds of "go to" statements in Java.
We illustrate the use of a label with a break statement in the following simple
example:
public static boolean hasZeroEntry (int[][] a) {
boolean foundFlag = false;
zeroSearch:
for (int i=0; i
