string builder

[ahmee]

StringBuilder builder1 = new StringBuilder() ;
StringBuilder builder2 = new StringBuilder(0 );
StringBuilder builder3 = new StringBuilder(1 00);

System.out.prin tln(builder1.ca pacity());
System.out.prin tln(builder2.ca pacity());
System.out.prin tln(builder3.ca pacity());

16
0
100
can any of tell me that why it give 16 output when first stringbuilder is call because it is empty string builder........ ..and what capacity do

Both questions (the capacity of a SB made with the no-arg constructor, and the purpose of "capacity") are covered in the StringBuilder API docs.
