IBM Java Toolbox for I programming support for IBM I subsystem In addition to queues, subsystems are also a major feature of IBM I. IBM I supports multiple types of jobs to meet the needs of the user. Different kinds of job requirements for system resources are different, for example, interactive jobs require faster response time, batch jobs may require more CPU

write a line in Events.txt to represent each time there was input from theServer, cook, or receiver. This would simulate the input for your program. You can choose the format each event. It should is possible to tell, by reading Events.txtWhich server entered each item and which cook prepared it. All output, for phase 1, should is printed to screen and/or the appropriate file. You'll create a fileCalled README.txt that would instruct the marker on how to run your program, which format to use fo

I. Multi-threaded KNOWLEDGE summary1. Thread SynchronizationThe knowledge about creating threads is not too much to describe. Let's start with the main story and talk about thread synchronization. As with the process synchronization in the operating system, the thread also faces the problem of resource sharing, and how to handle the resource sharing of threads is the most important place to use multithreading. In Java is the introduction of the concep

Newcachedthreadpool creates multithreading.NewscheduledthreadpoolThis thread pool can specify a fixed number of threads to be executed periodically. For example, by scheduleatfixedrate or Schedulewithfixeddelay to specify the cycle time.PS: In addition to write timed tasks (if not Quartz framework), it is best to use this thread pool to do, because it can ensure that there is always a live thread.Recommended way to use ThreadpoolexecutorIn the case o
