How to Split a mathematical expression on operators as delimiters, while keeping them in the result?

Question

I need to split an expression like

a+b-c*d/e 

and get a, b, c, d, e sepe

Answer 1

Just to get the a/b/c/d/e:

String myString = "a+b-c*d/e";
String[] result=myString.split("[-+*/]");

In a more readable form:

String myString = "a+b-c*d/e";
String[] result2=myString.split("["+Pattern.quote("+-*/")+"]");

To get the +-*/:

ArrayList list = new ArrayList();
for (char c:myString.toCharArray())
{
   if ("+-*/".contains(""+c)) list.add(c);
}
System.out.println(list);

Edit: removed unneeded escape characters.
