Doubt in String delete function.

[Rajesh Shinde]

Hi,

StringBuffer s=new StringBuffer("123456789");
s.delete(9,10);

Should this not give "StringIndexOutOfBoundsException", as the start index is 9 and s contains only 0-8 index values?

StringIndexOutOfBoundsException - if start is negative, greater than length(), or greater than end.
so your code not give exception becuse its length is 9
if you change it to

    StringBuffer s=new StringBuffer("123456789");
         s.delete(10,10);
  

then you get StringIndexOutOfBoundsException
vinit

Yes, This gives a exception as the start index is greater then String length.

I though it might throw exception if the start index is equal to the String length, as in that case also the String index is out of bound.(as there is no value at index=9)
