title: Make a string from an IntStream of code point numbers?
body: <p>If I am working with Java streams, and end up with an <a href="https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/stream/IntStream.html" rel="noreferrer"><code>IntStream</code></a> of <a href="https://en.wikipedia.org/wiki/Code_point" rel="noreferrer">code point</a> numbers for <a href="https://en.wikipedia.org/wiki/Unicode" rel="noreferrer">Unicode</a> characters, how can I render a <a href="https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/CharSequence.html" rel="noreferrer"><code>CharSequence</code></a> such as a <code>String</code>? </p>
  
  <pre><code>String output = "input_goes_here".codePoints(). ??? ;  
  </code></pre>
  
  <p>I have found a <code>codePoints()</code> method on several interfaces &amp; classes that all generate an <code>IntStream</code> of code points. Yet I have not been able to find any constructor or factory method that accepts the same.</p>
  
  <ul>
  <li><a href="https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/CharSequence.html#codePoints()" rel="noreferrer"><code>CharSequence::codePoints() → IntStream</code></a></li>
  <li><a href="https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/String.html#codePoints()" rel="noreferrer"><code>String::codePoints() → IntStream</code></a></li>
  <li><a href="https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/StringBuilder.html#codePoints()" rel="noreferrer"><code>StringBuilder::codePoints() → IntStream</code></a></li>
  </ul>
  
  <p>I am looking for the converse: </p>
  
  <p>➥ How to instantiate a <code>String</code> or <code>CharSequence</code> or such from an <code>IntStream</code> of code points?</p>
