How to create a completed future in java
future, java
Solution
Apache Commons Lang defines similar implementation that is called ConstantFuture, you can get it by calling:
Future<T> future = ConcurrentUtils.constantFuture(T myValue);
Problem
What is the best way to construct a completed future in Java? I have implemented my own `CompletedFuture` below, but was hoping something like this that already exists. ``` public class CompletedFuture<T> implements Future<T> { private final T result; public CompletedFuture(final T result) { this.result = result; } @Override public boolean cancel(final boolean b) { return false; } @Override public boolean isCancelled() { return false; } @Override public boolean isDone() { return true; } @Override public T get() throws InterruptedException, ExecutionException { return this.result; } @Override public T get(final long l, final TimeUnit timeUnit) throws InterruptedException, ExecutionException, TimeoutException { return get(); } } ```
