Just wondering, how would you check if a String has a character at a certain poisition?
Say String "cool" = hello
how would I make the equivelent of this:
if(cool.chatAt(4)!=null) {
doThis();
}
I know I can't use null with this, what would I use instead of null here?
first of all.
this is a wrng representation
String "cool" = hello
it shld be
String cool = "hello"; instead.
2nd of all characters are primitive types that have only 1 value either a letter or a number.
So your question doesnt make sense. "how would you check if a String has a character at a certain poisition?"
So can you please elaborate?
I realize the thing about the String, I am just writing shorthand.
I am saying, the string "cool".
How can I check if at the position(4) if there is a char there or not.
A String has characters for it's entire length. Are you trying to check for certain types of characters instead? e.g Non visible characters?
Forget the question, I was just having 2 types of strings inputed, one is one character shorter than the other. I was just trying to check if there was a character there on the shorter string. Doesn't matter though, I will just use .length()
oh..at that case you can use the strng length which would be a common way.
you can also charat(..)
just try combo of while loop and charat(..)
sir excuse me what does it mean by non visible charactersQuote:

Silly characters like space, carriage return, e.t.c
thanks..! :D thought it was something
