[Java learning notes] The Map interface sub-interface --- TreeMap, learning notes --- treemap
Similar to TreeSet, TreeMap can sort elements in a set and maintain the uniqueness of elements.
It should be noted that Comparable (The implementation interface should overwrite the comparaTo method) is used by Comparator.

Today comes a very interesting question: what happens in Java if a subinterface defines a method that already exists in the parent interface? Like what:Interface Irunnable extends runnable{void run ();At first I thought that the syntax of this kind of grammar should not be passed through the compiler, and did not expect this to be the compiler did not make any warning.Of course we wouldn't do it in most cases, because it doesn't seem to make much sens
There is a main interface, and then a thread is created to update the progress bar on the main interface.
The effect is as follows:

This article mainly introduces how to use Android handler. Handler can send messsage and runnable objects to the message queue of the thread associated with them. Each handler object is associated with the line threads that created it, and each handler object can be associated with only one line threads.
Handler generally have two purposes: 1) Perform a scheduled task, you can perform certain tasks on the scheduled implementation, and you can simulate the timer. 2) Inter-thread communic
, all of its methods inherit the method from the parent class collection. There are three practical classes in set: Hashset,treeset,linkedset.List interface:Collection sub-interfaces, which allow duplicate elements, are ordered . There are also three practical classes: Arraylist,linkedlist,vector. Queue interface:A collection of data that is waiting to be processed, in which the elements are generally in the FIFO (first-in, out) order, as well as the
In a dialog program, a sub-interface is usually a child control that, when toggled, usually hides the other, displaying the controls to be displayed.The following example has two buttons to control the display of two static text (click the button 1 will display the text 1, click on the text 2 will display the text 2)The implementation is divided into the following steps:1 Add static text and button member v
