整个设计采用java语言,利用面向对象思想。 首先,编写一个进程调度类Main_PCB,一个进程信息类PCB_block可以创建进程控制块( PCB)表示。进程控制块可以包含如下信息:进程名、优先数、到达时间、需要运行时间、已用CPU时间、进程状态等等。 对应成员变量是pcb_Name pcb_ID int pcb_Pro PCB_Begintime() pcb_Needtime pcb_Spendtime pcb_Finishtime String pcb_Statue 成员方法是pcb_Work () 可以实例化多个包含相同信息的进程,一个线程类Work允许多个进程共行的进程调度创建各自的模拟任务,由process_Create(int Process_ProcessNum)方法实现创建Process_ProcessNum个进程。 -whole design using java language, the use of object-oriented thinking. First, the process of preparation of a scheduling Main_PCB category, an Information PCB_block process can create process control block (PCB) said. Process control block may contain the following information : process, and priority number, arrival time, the need to run time CPU has spent time, the process of the state and so on. Corresponding member variables is pcb_Name pcb_ID int pcb_Pro PCB_Begin time () pcb_Needtime pcb_Spendtime pcb_Finis htime String pcb_Statue members is pcb_Work () can be examples many of the same information included in the process. Work like a thread allows multiple process held a total of the scheduling process to create their own simulations, by process_Create (int Process_ProcessNum) method
