求教

我定义了一个Book类 然后 定义他的构造函数为 public Book(int ID, String name, String[] authors, float price)
我在BookDemo类中 初始化这个类时 应该怎么写？
我是这样写的 但是错误的Book book = new Book(13,"二",{"杨二","杨三"},73.1f);

想问下 里边的数组怎么初始化啊？？

[sdojqy1122]

Book book = new Book(13,"二",new String[]{"杨二","杨三"},73.1f);

[sffx123]

改成这样Book book = new Book(13,"二",new String[]{"杨二","杨三"},73.1f);
或者提前声明String[] str = {"杨二","杨三"};
Book book = new Book(13,"二",str,73.1f);
