(FCFS)进程调度,求救……
刚学java,各位帮忙添加一下我的代码,虽然有点长,但是要实现的功能不是很复杂,主要是创建和启动进程(先来先服务算法)。而且界面方面已经实现。
主要问题是事件实现函数部分,不知道怎么写,怎么在创建进程完后,继续让进程运行……

最后:感激不尽……
第一类pcb
Java code

package process;


public class pcb {

    static final int Running=1;
    static final int Ready=2;
    static final int Waiting=3;
    private String processname;
    private int runtime;   //生存周期
    private int prority;    //优先级
    private int processstate;      //状态
    private int pcbflag;           //暂定
    public pcb(String name,int time,int pro)
    {
        this.processname=name;
        this.runtime=time;
        this.prority=pro;

    }
    public pcb()
    {
        pcbflag=0;
    }
    public void setprocessname(String name)
    {
        this.processname=name;

    }
    public String getprocessname()
    {
        return processname;
    }
    public void setruntime(int time)
    {
        this.runtime=time;

    }
    public int getruntime()
    {
        return runtime;
    }
    public void setprority(int pro)
    {
        this.prority=pro;
    }
    public int getprority()
    {
        return prority;
     }
    public void setprocessstate(int state)
    {
        this.processstate=state;
    }
    public String getprocessstate()
    {
        String s=new String();
        if(this.processstate==1)
        {
            s="runing";

        }
        else if(this.processstate==2)
        {
            s="ready";
        }
        else if(this.processstate==3)
            s="waiting";
        return s;

    }

}
