Question

I have field type string that can get two type of values on it:

1. simple field e.g. p1
2. complex fields p1/p2/p3/p4

Now I have 2 questions:

1. how can I identify that the type is complex with little effort as possible since
   the check is runs in loop?
2. when I got type complex I need to store the last two properties for
   example p3 and P4?

Answer 1

just use split operation and check length.

String[] prop = strprop.split("/");
if(prop.length > 1){
    String El = prop[prop.length];
    String El0 = prop[prop.length-1];
}
