StringBuilder trimToSize() method in Java with Examples
The trimToSize() method of StringBuilder class is the inbuilt method used to trims the capacity used for the character sequence of StringBuilder object. If the buffer used by StringBuilder object is larger than necessary to hold its current sequence of characters, then this method is called to resize the StringBuilder object for converting this object to more space-efficient. Calling this method may, but is not required to, affect the value returned by a subsequent call to the capacity() method.
public void trimToSize()
Returns: This method does not return anything.
Below programs illustrate the StringBuilder.trimToSize() method:
Capacity before applying trimToSize() = 29 String = GeeksForGeeksContribute Capacity after applying trimToSize() = 23
Capacity before applying trimToSize() = 34 String = GeeksForGeeks classes Capacity after applying trimToSize() = 21
