What are string methods in Java?
String methods in Java are built-in functions that allow you to manipulate and work with strings, such as concatenation, substring extraction, and searching.
Can you give me some examples of commonly used string methods?
Sure! Common string methods include length(), charAt(), substring(), indexOf(), and toLowerCase().
How do I use the substring() method?
The substring(int beginIndex, int endIndex) method returns a new string that is a substring of the original string, starting from beginIndex and ending at endIndex - 1.
What happens if I provide an invalid index?
If you provide an invalid index, such as one that is out of bounds, it will throw a StringIndexOutOfBoundsException.
