title: Bad to use very large strings? (Java)
body: <p>Are there any negatives to creating huge strings?  For instance, if we're reading in text from a potentially huge text file:</p>
  <pre><code>while (scanner.hasNext()) {
    someString += scanner.next();
  }
  // do something cool with some string
  </code></pre>
  <p>Would processing the file line by line be (generally) a better solution, and why?</p>
