String return question

k1ll3r_x · 11-10-2004, 01:48 PM

Code:

public class class1
{
   public static void main (string [] args)
{
    int i=3,j=4;
    char c[]={'a','b','c','d','e','f','g','h','i'};
    String s= new String (c,i,j);
    System.out.print(s);
}
}

why does it return

PHP Code:



defg

?

string offsets start counting at zero not one.

Code:

0 1 2 3 4 5 6 7 8 
a b c d e f g h i

yea but isnt it suppossed to start at 3 and return one? because i think its the value of [i - j] which would equal 1 and return character D only??

the third parameter is a length, not an absolute offset, so its 3 to 3+4=7 = g.

You've asked a couple of extremely similar questions i've noticed... they read very much like homework, and not questions you are likely to come across in the course of private work... if this is the case, please do not ask these questions, as they are or you to find out and not to blindy copy an answer from LQ.

but either way you could have easily found out your answer by looking at the java api.....
