How to return the contents of an array?

Question

Java

There is a method to which the argument is passed as an array of 10 characters.
Then he must present the array as a whole word and return it for further manipulations.

private static String totalunique(String[] unique) {
        for (String stringunique : unique) {
            System.out.print(stringunique);
        }
        return null;
    }

There were problems:
A variable of type String is declared only in the for loop, otherwise it gives an error that a semicolon is missing.

private static String totalunique(String[] unique) {
        String stringunique = null;
        for (stringunique : unique)(здесь будет подчеркнуто красным и говорить expected ;) {
            System.out.print(stringunique);
        }
        return stringunique;
    }

And in the log there will be Error:(29, 14) java: bad initializer for for-loop
