This is called programming to interface. This will be helpful in case if you wish to move to some other implementation of list in the future. If you want some methods inArrayListThen you wowould need to program to the implementation that isArrayList a = new ArrayList().
The main reason you 'd do this is to decouple your code from a specific implementation of the interface. When you write your code like th

For a linked list, we need to use a specific threshold to complete its differentiation, so that the node is less than or equal to the value of the previous, the node is greater than the value of the next, while ensuring that the two types of nodes within the position of the same relationship.
Given a list of head node heads, at the same time given a threshold Val, return a linked
The Java1.5 adds new features:Variable parameters:For cases where the parameter number is indeterminate and the type is determined, Java handles the mutable parameter as an array.Note: The mutable parameter must be in the last item .When there is more than one variable parameter, there must be one that is not the last, so only one variable parameter is supported .Because of the variable number of arguments, Java cannot differentiate whether the passed
First, ArrayList bottom realization principleContrastUnlike vectors,operations in ArrayList are not thread-safe ! Therefore, it is recommended that you use ArrayList in a single thread, and you can select vectors or copyonwritearraylist in multiple threads.Summary :ArrayList actually saves the data through an array . When we construct ArrayList, if we use the default constructor, the default capacity size of ArrayList is ten.(02) When the ArrayList capacity is insufficient to accommodate all ele
