Thinking in java constructor initialization
<p>I have a question on page 128 of Bruce Eckel's Thinking In Java 4th Edition, the second paragraph, the last sentence it asks:</p>

<blockquote>
  <p>what would happen if an overloaded constructor were defined that did not initialize <code>w3</code> and there wasn’t a “default” initialization for <code>w3</code> in its definition?</p>
</blockquote>

<p>I found this statement is confusing to understand, could experts or readers of this book help me a little? Thanks! </p>
