The java code is implemented as follows: package cn. Speed up a slow Android device Fix an Android device that wont charge or turn on Fix an Android device thats restarting or crashing Fix an Android device that freezes or wont respond Fix a screen that isnt working right on Android Reset your Android device to factory settings Get manufacturer help for your device Fix Bluetooth. The arrangement effect of Zset is shown in the following figure: Note that it is not necessary to traverse the whole Zset Set to avoid performance waste. In this way, an endless loop thread will be started to continuously take the first key value, If the current timestamp is greater than or equal to the key value, the socre will take it out for consumption and deletion, so as to delay the execution. In the operation, the key is understood as the name of Zset, so what is the use for the delay queue? Imagine that if score represents the timestamp of the execution time, and it is inserted into the Zset Set at a certain time, it will be sorted according to the timestamp size, that is, before and after the execution time.

It can be understood as a data table with two columns of fields, one for value and the other for sequence number. After each assignment, Zset will automatically adjust the order according to the new value. This attribute can be specified when adding and modifying elements. In addition to adding data value, it also provides another attribute score. YouTube or video player apps show the video as late as the delay time of the audio in order to eliminate. The time when the sound actually comes out of the earbuds. In essence, Zset adds a sorting function to the Set structure. The time when sound playback starts on the device (smartphone, etc.) 2. Following the previous implementation of delay queue with rabbitMQ, Redis can also implement delay operation due to its own Zset data structure
