title: Java Apache poi 4.1.2 comparing cell type
body: <p>I tried to find similar questions on stack, but unfortunately none of them fully helps me.
  Before new release, I have following code:</p>
  
  <pre><code> if (c1.getCellType() == CellType.STRING) { //do sth }
  </code></pre>
  
  <p>After update I can not use it, because </p>
  
  <blockquote>
    <p>CellType.STRING</p>
  </blockquote>
  
  <p>is no longer supported. How should I fix it?</p>
  
  <p>I found solution:</p>
  
  <pre><code>switch (cell.getCellType()) {
    case STRING:
      //Do something
      break;
  }
  </code></pre>
  
  <p>But I have no idea what is STRING? From which 'import' should it be?</p>
