Run time error

Code :

---

class yam
{
public static void findIndex()
{
String s="allendowlley";
int index=0;
int l=s.length();
while(index<l)
{
index=s.indexOf('l',index);
System.out.println(index);
index=index+1;
}
}
public static void main(String args[])
{
findIndex();
}
}

---

The program keeps looping endlessly. I can't figure out why.

I was able to end the infinite loop but I'm not sure if the output is still what you're looking for. I'm still kind of new to the Java scene. I replaced the while loop with a for loop...

class yam
{
public static void findIndex()
{
String s="allendowlley";
int index=0;
int l=s.length();
for(int i = 0; i<l; i++)
{
index = i;
index=s.indexOf('l',index);
System.out.println(index);
index=index+1;
}
}
public static void main(String args[])
{
findIndex();
}
}
