Ppt Multithreading In Java Powerpoint Presentation Free Download This document provides an overview of threads in java, including: threads allow for multitasking by executing multiple processes simultaneously. they are lightweight processes that exist within a process and share system resources. Scenario #1 a “manager” thread and n “worker” threads manager starts workers but then must wait for them to finish before doing follow up work solution: manager creates a countdownlatch with value n after workers starts, manager calls await() on that when each worker completes its work, it calls countdown() on the latch after all n call countdown(), manager is un blocked and does follow up work example use: parallel divide and conquer like mergesort code example: syncdemo0.java scenario #2 a “manager” thread and n “worker” threads manager starts workers but wants them to “hold” before doing real work until it says “go” solution: manager creates a countdownlatch with value 1 after each workers start, it calls await() on that latch at some point, when ready, the manager calls countdown() on that latch now workers free to continue with their work code example: syncdemo1.java scenario #3 work done in “rounds” where: all workers wait for manager to say “go” each worker does its job and then waits for next round manager waits for all workers to complete a round, then does some follow up work when that’s done, manager starts next round by telling workers “go” solution: combine the two previous solutions first latch: hold workers until manager is ready second latch: manager waits until workers finish a round worker’s run() has loop to repeat manager must manage latches, recreating them at end of round example use: a card game or anything that has that kind of structure code example: syncdemo2.java summary of last section multiple threads may need to cooperate common situation: some workers and a manager one thread may need to wait for one or more thread to complete one or more threads may need to wait to be “released” or a combination of these situations threads all access a countdownlatch await() used to wait for enough calls to countdown() end unused slides follow dfafaf work thr a work thr a work to do thr a await.
