what callable

Java has several thread-related classes or interfaces, such as Runnable, Callable, Future, and FutureTask. They are also important concepts in Java, let's take a simple example below to learn the differences between them.Runnable Among them,

Callable and future The callable interface defines a call method that can act as the executing body of a thread, but the call method is more powerful than the Run method: A, call method can have return valueB, the call method can declare an

First, callable and RunnableLet's talk about Java.lang.Runnable, it's an interface that only declares a run () method in it: Public Interface Runnable { publicabstractvoid run ();}Because the run () method returns a value of type void, No

Introduction of callable and future callable and The future two feature is Java in subsequent versions in order to adapt to multi-method to join, callable is similar to runnable interface, Classes that implement callable interfaces and

in the previous article we talked about the 2 ways to create threads, one is to inherit the thread directly, and the other is to implement the Runnable interface. One drawback to all 2 of these approaches is that you cannot get the results of the

English documents:callable(object)Return True If the object argument appears callable, False if not. If this returns true, it's still possible that a call fails and if it is false, calling object would never Succe Ed. Note That classes is callable

Java concurrent Programming callable, Runnable, future, Futuretask　　Java has callable, Runnable, future, futuretask these thread-related classes or interfaces, below to understand their role and differences.I. Callable and runnable　　Similar to

Since Java 5, Java provides the callable interface. The callable interface provides a call method that can be used as the thread's execution body, but the call method is more powerful than the run method. Mainly reflected in: 1. The call method can

Callable, Future, and FutureTask In Java, besides the Runnable interface, there are also Callable interfaces.The difference between the two is that the latter can return values, which are generally used for time-consuming computing.The Runnable

Callable and futureThe Executor framework divides the unit of work into tasks, that is, the task is a logical unit of work, and the thread is the mechanism by which the task executes asynchronously. Runnable is an abstraction of the task, and the

1.RunnableRunnable is an interface that is very simple to use: 1. Implement the interface and override the Run Method 2. Create thread 3 with objects of this class. The Run method that automatically calls the object when the thread starts is
