java - int 数组或字符串数​​组或我错了

Question

我试图将日期和时间放入数组中，但我收到错误，因为我不能将日期/时间或只是变量，我尝试将 int 数组更改为字符串，但我收到错误，它无法解析为变量

private static void listM() {
        // TODO Auto-generated method stub
        System.out.println("Here is the list of Movie(s) to select from," // gives user a list of movies to choose from
                + "\nPlease enter its respective ID:\n"
                + "1. Captain America\t|2. Toy Story\t|3. Jumanji\n4. Black Panther\t|"
                + "5. Green Lantern\t|6. Detective Pikachu\n7. Thor\t|8. 2012\t|9. Geostorm\n");

                 System.out.println("");
         Scanner scanner = new Scanner(System.in);  //use scanner to get ID of Movie  

         System.out.print("Input the ID of the Movies to view their information: ");
         int idmovie = scanner.nextInt();

            String[] movie = new String[9];   //make an array to store the movie information
            movie[0] = test;
            movie[1] = Captain;
            movie[2] = xxx;
            movie[3] = xxx;
            movie[4] = xxx;
            movie[5] = xxx;
            movie[6] = xxx;
            movie[7] = xxx;
            movie[8] = xxx;

Answer 1

您需要在字符串周围加上引号。当您编写 movie[0] = test; 时，java 会尝试将名为 test 的变量的值放入电影数组中。因为您没有定义名为 test 的变量，Java 将抛出您收到的错误。

以下是您可能想要定义数组的方式:

movie[0] = "test";
