Question

I have a class called jobType

package pcs_assignment_2;

public class JobType
{
    private int ID;
    private double aTime;
    private double sTime;

    public JobType(int ID, double aTime, double sTime)
    {
        this.ID = ID;
        this.aTime = aTime;
        this.sTime = sTime;
    }

    public int getID() {
        return ID;
    }

    public void setID(int ID) {
        this.ID = ID;
    }

    public double getaTime() {
        return aTime;
    }

    public void setaTime(double aTime) {
        this.aTime = aTime;
    }

    public double getsTime() {
        return sTime;
    }

    public void setsTime(double sTime) {
        this.sTime = sTime;
    }

    public String toString() {
        return "JobType{" + "ID=" + ID + "aTime=" + aTime + "sTime=" + sTime + '}';
    }

}

Now what I wanna have is a PriorityQue of Type JobType which sorts the queue on the basis of sTime. Is it possible?

Answer 1

A custom comparator needs to be written, see the code below.
here 10 in the initial capacity of the queue.

    new PriorityQueue<JobType>(10, new Comparator<JobType>() {

    @Override
    public int compare(JobType o1, JobType o2) {
             return Double.compare(o1.sTime,o2.sTime); 
    }
    });
