Hello all,

I have a simple question regarding declare of veriables.
I have the following task:
if (type == "xx")
{
String[] yy = {"a", "b", "c"}; <--here I have a message(Local variable is never read)
}
else
{
String[] yy = {"d", "e", "f"};<--here I have a message(Local variable is never read)
}

So I need to declare an array depending on "type" value, but my arrays are not seen for future using.
Please help me with this question.

Thanks in advance!

Declare the array outside the if-else like

String[] yy;

if (type == "xx")
    yy = {"a", "b", "c"}; 
else
  yy = {"d", "e", "f"};

Variables only exist within the { } where they are declared in

Yes, I've tried such way, but I have the following error:

String[] yy;
if (type == "xx")
yy = {"a", "b", "c"}; <--Array constants can only be used in initializers
else
yy = {"d", "e", "f"};<--Error: Array constants can only be used in initializers

Oops, my bad :)

String[] yy;

if (type == "xx")
    yy = new String[]  {"a", "b", "c"}; 
else
  yy = new String[]  {"d", "e", "f"};
