java - Hardcode an Array in a For Loop -

i trying write java class needs short possible (line-wise). within class, have following code:

char[] myarray = {'a', 'b', 'c', 'd'}; for(char c : myarray) ... 

in order make shorter, iterating on same chars, thought might able this:

for(char c : {'a', 'b', 'c', 'd'}) ... 

however, doesn't work , cannot find online show me how (i'm not sure search this).

is possible in different way? or can not made shorter?

if chars form consecutive pattern, can use

for (char c = 'a'; c <= 'd'; c++) 

if don't, use

for (char c : new char[] {'c', 'a', 'b'}) 

or

char[] arr = {'c', 'a', 'b'};    (char c : arr) 

or

for (char c : "cab".tochararray())
