How can I clear or empty a StringBuilder? – Read For Learn



ways that work:

  1. Use stringBuilderObj.setLength(0).
  2. Allocate a new one with new StringBuilder() instead of clearing the buffer. Note that for performance-critical code paths, this approach can be significantly slower than the setLength-based approach (since a new object with a new buffer needs to be allocated, the old object becomes eligible for GC etc).
