• A portion of a string.
• substring(beginIndex, endIndex) where
• beginIndex is the first character of the desired substring,
• endIndex is the last character, non-inclusive.
• the first character in a string is index 0.
• Yes, it is confusing, and it is the same way in Java.
• Get a single character: charAt(position)
• Find a substring: indexOf(string), indexOf (string, startPosition) where
• string is the substring you want to find in the string.
• startPosition is the position from which you want to start searching.
