1, callable: Callable The task that returns the result and may throw an exception. The implementing person defines a method called call without any arguments. The callable interface is similar to Runnable, both of which are designed for classes whose instances might be executed by another thread. However, Runnable does not return a result and cannot throw a checked exception. The Executors class contains some practical methods for converting from other common forms into callable classes. Cal

Ajax "IT168" Ajax is a combination of several sophisticated technologies designed to give users a more satisfying user experience from Web applications. This paper reviews the evolution of enterprise application architecture and tries to expound that Ajax is the inevitable product of B/s architecture development, but Ajax seems to have a bleak future because of the congenitally deficient JavaScript programming language that Ajax relies on for survival

With future upgrades to file system protocols, such as NFS (including concurrent NFS, or PNFS), will NFS potentially replace many of the existing proprietary file systems? Let's take digitalfilm tree for example, a company in Hollywood that provides post-processing and virtual effects services for the entertainment industry.

Public interface callable .public interface future The future represents the result of an asynchronous calculation. You can only use the get method to get the results after the calculation is complete 1. Thread Processing returns resultsIn general development, using multi-threading, the most common is: 1. Implement the Runnable interface; 2. Inherit the thread class.But the Run method is not returning resul

In an interactive meeting, some students mentioned in the film's future interaction, aroused my interest, so collected some of the film's data, do some superficial analysis, hope to be able to provoke some thinking.

Runnable encapsulates a task that runs asynchronously, without an asynchronous method with parameters that do not have return values. Callable and runnable are similar, but there are return values, and the callable interface is a parameterized type, with only one method call. The parameter type is the return value type. In fact, the interface will run a task that produces a result. Package java.util.concurrent; Public interface Callable Future
