This article mainly introduces "how to understand the Promise pattern in java". In daily operation, I believe many people have doubts about how to understand the Promise pattern in java. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "how to understand the Promise pattern in java"! Next, please follow the editor to study!

1. Promise mode is an asynchronous programming mode. The core is that when task An is executed, the execution result can be obtained through the promise object.

So there is no need to synchronously wait for task A to finish before executing task B. When task B requires task A to execute task B, when the result of task An execution is required, it can be obtained through this promise object (such as listening for beeps).

2. Programs run faster in programs, because Promise can avoid unnecessary waiting and improve support for concurrency.

Example

/ * make tea * * @ author ajin * / public class BoilWater {boolean status = false; public boolean isStatus () {return status;} public void setStatus (boolean status) {this.status = status;}} / * prepare teacup and tea * * @ author ajin * / public class TeaAndCup {boolean status = false; public boolean isStatus () {return status } public void setStatus (boolean status) {this.status = status;}} at this point, the study on "how to understand the Promise pattern in java" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
