电影类的另一个完整示例：

public class A {

    public static void main(String[] args) {

        class Movie {

            String movieName;
            String genre;
            String movieType;
            String year;
            String ageRating;
            String rating;

            public Movie(String [] str)
            {
                this.movieName = str[0];
                this.genre = str[1];
                this.movieType = str[2];
                this.year = str[3];
                this.ageRating = str[4];
                this.rating = str[5];
            }
        }

        String [] movieDetailArr = {"Inception", "Thriller", "MovieType", "2010", "13+", "10/10"};

        Movie mv = new Movie(movieDetailArr);

        System.out.println("Movie Name: "+ mv.movieName);
        System.out.println("Movie genre: "+ mv.genre);
        System.out.println("Movie type: "+ mv.movieType);
        System.out.println("Movie year: "+ mv.year);
        System.out.println("Movie age : "+ mv.ageRating);
        System.out.println("Movie  rating: "+ mv.rating);
    }
}

或者，

// Either method works
String arrayName[] = new String[10];
String[] arrayName = new String[10];

它声明了一个名为arrayName的数组，大小为10（您可以使用元素0到9）。

此外，如果您需要更动态的内容，可以使用List界面。这不会表现得很好，但更灵活：

List<String> listOfString = new ArrayList<String>();

listOfString.add("foo");
listOfString.add("bar");

String value = listOfString.get(0);
assertEquals( value, "foo" );

如果要使用反射创建阵列，可以执行以下操作：

 int size = 3;
 int[] intArray = (int[]) Array.newInstance(int.class, size ); 

如果“array”是指使用java.util.Arrays，那么可以使用：

List<String> number = Arrays.asList("1", "2", "3");

// Out: ["1", "2", "3"]

这个非常简单明了。
