Split numbers and letters in an Alphanumeric String

I need to split an Alphanumeric String and split the alphabets and numbers. For example, if I have a string like: "Room 502", I need to get the number 502 as a separate string to "Room". Could someone please help me with this?

I know it's probably something so simple, but all the examples I have seen don't seem to do what I need.

For this example, you could just split on the space character, since the string is literally Room 502 and you want Room and 502, you could just do:

String example = "Room 502";
String[] components = string.split(" ");

If what you are trying to split is a bit more complex, for example Room502isnice as suggested in the comments, we have to use something called a regular expression, or regex.

The following regular expression would split the string Room502isnice into Room, 502 and isnice:

([A-z]+)|(\d+)

I'm not an expert in Java so I'm not 100% sure how it would be applied in Java.

See this regexr example: http://regexr.com/399uu
