toString method
A string representation of this object.
Some classes have a default textual representation,
often paired with a static parse
function (like int.parse).
These classes will provide the textual representation as
their string representation.
Other classes have no meaningful textual representation
that a program will care about.
Such classes will typically override toString
to provide
useful information when inspecting the object,
mainly for debugging or logging.
Implementation
@override
String toString() {
StringBuffer sb = StringBuffer();
sb.write('<ShortStack vector:[');
for (int i = 0; i < _vector.length; i++) {
if (i > 0) {
sb.write(' ');
}
if (i == _top) {
sb.write('>>');
}
sb.write(_vector[i]);
if (i == _top) {
sb.write('<<');
}
}
sb.write(']>');
return sb.toString();
}
