我对一般编程很陌生，我一直在尝试为我的计算机科学类(class)用 java 构建一个系统，但在 eclipse 中收到错误“无法从 int[] 转换为 int”。

public static ArrayList<Book> CreateBooksArrayList(){
    int[] id = {1,2,3,4,5};
    String[] bookTitle = {"book1", "book2", "book3", "book4", "book5"};
    String[] authorName = {"author1", "author2", "author3", "author4", "author5"};
    double[] bookReleaseYear = {123,456,789,987,654};
    int[] numOnLoan = {1,2,2,3,4};
    int[] numInStock = {5,5,5,5,5};


    int bID = -1;
    String bTitle = null;
    String aName = null;
    double bRelease = -1;
    int nLoan = -1;
    int nStock = -1;

    ArrayList<Book> Books = new ArrayList<Book>();
    for (int i = 0; i<6; i++){
        bID = id[i];
        bTitle = bookTitle[i];
        aName = authorName[i];
        bRelease = bookReleaseYear[i];
        nLoan = numOnLoan;
        nStock = numInStock;
        Books.add(new Book(bID, bTitle, aName, bRelease, nLoan, nStock));

我尝试寻找答案，但我似乎找不到与此确切问题相关的任何链接。预先感谢您的帮助!

Answer 1

您忘记了 for 循环中 numOnLoan 和 numInStock 的 [i] 部分。将它们都更改为包含 [i]。

nLoan = numOnLoan[i];
nStock = numInStock[i];
