string split in java

I have this Key - Value , and I want to separate them from each other and get return like below:

String a = "Key"
String b = "Value"

so whats the easiest way to do it ?

Answer 1

String[] tok = "Key - Value".split(" - ", 2);
// TODO: check that tok.length==2 (if it isn't, the input string was malformed)
String a = tok[0];
String b = tok[1];

The " - " is a regular expression; it can be tweaked if you need to be more flexible about what constitutes a valid separator (e.g. to make the spaces optional, or to allow multiple consecutive spaces).
