Could anyone tell me what's wrong with my solution, cause i can't find any mistake with it.

public static Object[] sortArray(Object names){
	if(names.getClass().isArray()){
		int length = Array.getLength(names);
		Object[] array = new Object[length];       
		for (int i = 0; i < length; i++) {
			array[i] = (Array.get(names, i));
		}
		if(length > 1){Arrays.sort(array);}
		return array;			
	}
	else{
		return new Object[]{names};
	}	
}
