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
String toString() {
StringBuffer buf = new StringBuffer();
if (elt[0] != null) {
buf.write("A:");
buf.write(elt[0].toString());
}
if (elt[1] != null) {
buf.write(" B:");
buf.write(elt[1].toString());
}
return buf.toString();
}
