Java syntax 183
outer:
for (int i = 0; i < 10; i++) {
}
while (true) {
}
break outer;
// Will break to this point
continue statement
The continue statement discontinues the current iteration of the current control statement and begins the next
iteration. The following while loop in the code above reads characters by calling getChar(), skipping the statements
in the body of the loop if the characters are spaces:
int ch;
while (ch = getChar()) {
}
if (ch == ' ')
continue; // Skips the rest of the while-loop
// Rest of the while-loop, will not be reached if ch == ' '
doSomething();
Labels can be specified in continue statements, as they can in break statements:
outer:
for (String str : stringsArr) {
}
char[] strChars = str.toCharArray();
for (char ch : strChars) {
}
if (ch == ' ') {
}
return statement
/* Continues the outer cycle and the next
string is retrieved from stringsArr */
continue outer;
doSomething(ch);
The return statement is used to end method execution and to return a value. A value returned by the method is
written after the return keyword. If the method returns anything but void, it must use the return statement to return
some value.
void doSomething(boolean streamClosed) {
}
// If streamClosed is true, execution is stopped
if (streamClosed) {
}
return;
readFromStream();
