title: How to replace a String starting with $ character using Java's String.replaceAll method
body: <p>What's the correct regex for a String starting with $ char as the first argument (i.e. the string to replace) to Java's replaceAll method in the String class? I can't get the syntax right.
  Example</p>
  
  <pre><code>String s = "SUMIF($C$6:$C$475,\"   India - Hyd\",K$6:K$475)";
  System.out.println(s.replaceAll("$475", "$44"));
  </code></pre>
