Finding the String

I have a quick question on how to do something. So what I want to do is define a string inside a sentence. For instance if I wanted to find the tenth letter of "Hello this is a test example thing" and define it in a string how would i do that?

 

To get a given character:

Code:

String xCharacter = str.substring(x - 1, x);

Where x is the index in the String of the character you want to get.

 

Alright, thanks for the quick reply!

Also, do you know how I can find a specific letter/number in a string?

If you want to check if a String contains a certain character sequence, you can do the comparison:

Code:

if (!str.equals(str.replace("stringToSearchFor"))){
    // str contains String
}
