Eclipse Juno does not support lambdas (or Java 8 in general). You need to be using Eclipse Mars (or Luna) for full Java 8 support.

change it to 

int[] c = Arrays.stream(c1).mapToInt(Integer::parseInt).toArray();

no need of round brackets (parenthese) for method references Integer::parseInt is enough
