list arraylist

List is an interface, while ListArray is a class.ListArray inherits and implements the List.Therefore, the List cannot be constructed, but a reference can be created for the List as above, and ListArray can be constructed.List list; // correct list =

 Differences and usage of arraylist vector sort list Arraylist and vector use arrays to store data. The number of elements in the array is greater than that in the actual storage to add and insert elements. Both allow direct serial number index

ArrayList is a complex version of an array. The ArrayList class provides some functions that are provided in most Collections classes but not in the Array class. For example: The Array capacity is fixed, and the ArrayList capacity is automatically

Containers are an important part of the Java language learning. Mason my feeling is just beginning very difficult to learn, but so you know it, contact more, also "logical" to understand. Java's container classes are mainly derived from two

In the course Lecture03 _ application framework and key components _ 1, the instructor introduced that Intent is the medium for passing parameters between Activity and Service, the usage and example of using Intent and Bundle to transmit data
