https://docs.vultr.com/java/examples/clear-the-stringbuffer Reset StringBuffer content in Java In Java, you can reset the content of a StringBuffer using the setLength(0) method, which clears its content while retaining the existing capacity. For example, stringBuffer.setLength(0); effectively empties the buffer. Alternatively, reassigning a new instance (stringBuffer = new StringBuffer();) creates a fresh buffer. These methods are commonly used in string manipulation to optimize performance in applications requiring frequent modifications to dynamic text data
