length() and capacity() method

StringBuffer:

length() and capacity()

The length of the StringBuffer can be found by the length() method.while the total capacity can be found through the capacity() method.They have the following forms:

                      int length();

                      int capacity();

package stringdemo;

public class LengthAndCapacity {

    public static void main(String[] args) {

        StringBuffer s= new StringBuffer("Dance");

        

        System.out.println("Length="+s.length());

        System.out.println("Capacity"+s.capacity());

    }

}

OUTPUT:

Length=5

Capacity21

Here Length is 5 and capacity is 21 because room for 16 additional characters is automatically added,so result is 21.
