Answer 1

class str
{
public static void main(String args[])
{
String s= "She was feeding the little rabbit with an apple";
s=s.toUpperCase();
int i,l,c=0;
char ch,ch1;
l= s.length();
for(i=0;i<l-1;i++)
{
ch= s.charAt(i);
ch1= s.charAt(i+1);
if(ch==ch1)
c++;
}
System.out.println(c);
}
}

Answer 2

In line 13 you have
ch1= s.charAt(i+l);
that points to a char outside of the string since l is equal to the string length.

Answer 3

You should only loop until l-1, because you are using i+1 inside the loop

As an additional note: don't use l as a variable, since l and I (small l and large i) look the same in some fonts

Answer 4

Thats the online line which needs a fix:

instead of
for(i=0;i<l;i++)

use
for(i=0;i<l-1;i++)

Answer 5

You also changed line 13 from i+1 to i+l, which was not necessary.
Now it should work
