toString method

String toString()

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() {
  String s = "";
  s += "[";
  for (int i = 0; i < m; i++) {
    s += "(";
    for (int j = 0; j < n; j++) {
      s += entries[i][j].toString();
      s += " | ";
    }
    s += "),   ";
  }
  s += "]";
  return s;
}
