The CompletableFuture class in Java provides the isDone() method to check if a CompletableFuture has completed. Introduction The CompletableFuture.isDone() method is used to check if a CompletableFuture has completed, whether normally or exceptionally. This is useful for polling the status of an asynchronous computation without blocking the calling thread. isDone Method Syntax The syntax for …
The CompletableFuture class in Java provides the get() method to retrieve the result of a CompletableFuture when it completes. Introduction The CompletableFuture.get() method is used to retrieve the result of a CompletableFuture once it completes. It blocks the calling thread until the future is complete, making it useful for waiting for the result of asynchronous …
The CompletableFuture class in Java provides the thenAcceptBoth() method to perform an action when two CompletableFuture instances complete. Introduction The CompletableFuture.thenAcceptBoth() method is used to perform a specified action when both CompletableFuture instances complete. It takes a BiConsumer that processes the results of both futures and returns a new CompletableFuture that is completed when the …
The CompletableFuture class in Java provides the thenCombine() method to combine the results of two CompletableFuture instances when both complete. Introduction The CompletableFuture.thenCombine() method is used to combine the results of two CompletableFuture instances once both complete. It takes a BiFunction that processes the results of both futures and returns a new CompletableFuture with the …
The CompletableFuture class in Java provides the thenRun() method to run a specified action when the CompletableFuture completes. Introduction The CompletableFuture.thenRun() method is used to execute a Runnable action after a CompletableFuture completes, regardless of the result. This is useful for running tasks that do not depend on the result of the CompletableFuture. thenRun Method …
The CompletableFuture class in Java provides the thenAccept() method to consume the result of a CompletableFuture when it completes. Introduction The CompletableFuture.thenAccept() method is used to process the result of a CompletableFuture once it completes. It takes a Consumer that processes the result but does not return any value. thenAccept Method Syntax The syntax for …
The CompletableFuture class in Java provides the thenApply() method to transform the result of a CompletableFuture when it completes. Introduction The CompletableFuture.thenApply() method is used to process and transform the result of a CompletableFuture once it completes. It takes a function that processes the result and returns a new CompletableFuture with the transformed result. thenApply …
The CompletableFuture class in Java provides the completeExceptionally() method to complete a CompletableFuture with an exception. Introduction The CompletableFuture.completeExceptionally() method is used to complete a CompletableFuture with an exception. This can be useful when you need to signal that an error has occurred in an asynchronous computation. completeExceptionally Method Syntax The syntax for the completeExceptionally …

The CompletableFuture class in Java provides the complete() method to manually complete a CompletableFuture with a specified value. Introduction The CompletableFuture.complete() method is used to manually complete a CompletableFuture with a specified value. This can be useful when you need to programmatically control the completion of a future, such as when a result is obtained …
The CompletableFuture class in Java provides the runAsync() method to run a task asynchronously without returning a result. Introduction The CompletableFuture.runAsync() method is used to run a task asynchronously and return a CompletableFuture that will be completed when the task is finished. This is useful in asynchronous programming when you need to perform non-blocking operations …
The CompletableFuture class in Java provides the supplyAsync() method to run a task asynchronously and return a CompletableFuture that holds the result of the task. Introduction The CompletableFuture.supplyAsync() method is used to run a task asynchronously and return a CompletableFuture that will be completed with the result of the task. This is useful in asynchronous …
