1. Arrays类介绍 This class contains various methods for manipulating arrays (such as sorting and searching). This class also contains a static factory that allows arrays to be viewed as lists. 该类包含用于操作数组的各种方法(例如排序和搜索)。该类还包含一个静态工厂,允许将数组视为列表。 根据注释...
Static methods for manipulating arrays are available in the java.util.Arrays and java.System classes. Assume the following declarations, where T is the array element type, either a primitive, object or either kind of type depending on which method is being called. T x, key; // This type T...
