Returns true if the two specified arrays of Objects are equal to one another. static booleanequals(short[] a, short[] a2) Returns true if the two specified arrays of shorts are equal to one another. static voidfill(boolean[] a, boolean val) Assigns the specified boolean value to each el...
Java Class Library (Coursera) Java Class Library is the fourth and final course in the Core Java Specialization. After completing this course, you will be able to write reusable code that remains type-safe using Java Generics, work with collections of objects, work with files, handle runtime ...

public class Arrays extends Object 此类包含用来操作数组(比如排序和搜索)的各种方法。此类还包含一个允许将数组作为列表来查看的静态工厂。 除非特别注明,否则如果指定数组引用为 null,则此类中的方法都会抛出 NullPointerException。 此类中所含方法的文档都包括对实现 的简短描述。应该将这些描述视为实现注意事项,而...
Arrays of objects that have a class constructor are initialized by the constructor. When there are fewer items in the initializer list than elements in the array, the default constructor is used for the remaining elements. If no default constructor is defined for the class, the initializer list...
