在一个名为ArraySorts的实用类中,有一个Melon数组、前面的Comparator数组和insertionSortWithComparator()方法,我们可以编写如下内容: 代码语言:javascript 代码运行次数:0 运行 复制 Melon[] melons = {...}; ArraySorts.insertionSortWithComparator(melons, byType); 对于较小且大部分排序的数组,这可能会很快。此外...

第一种形式的参数 name 表示的是类的全名; initialize 表示是否初始化类;loader 表示加载时使用的类加载器。第二种形式则相当于设置了参数 initialize 的值为 true,loader 的值为当前类的类加载器。Class.forName 的一个很常见的用法是在加载数据库驱动的时候。如 Class.forName("org.apache.derby.jdbc.Embedded...
Every array also belongs to a class that is reflected as a Class object that is shared by all arrays with the same element type and number of dimensions. The primitive Java types (boolean, byte, char, short, int, long, float, and double), and the keyword void are also represented as ...
