Nice and simple toString(): 
<pre>
  public String toString() {

    return MyClass.class.getSimpleName()

        + new LinkedHashMap<Object, Object>() {{

      put("foo", foo);

      put("bar", bar);

      put("tee", tee);

    }};

  }
</pre>
Results in:

  MyClass[foo: fooValue, bar: barValue, tee: teeValue]
