title: Is there a Java equivalent or custom method for 'string.Insert()' in C#
body: <p>I am trying to port some code from C# and I have come across</p>
  
  <pre><code>string.Insert(int startIndex, string value)
  </code></pre>
  
  <p>and there doesn't seem to be an obvious Java equivalent. Could anyone please help me with this issue and what I can do to solve it. Thank you in advance.</p>
