Stupid Prob

[tHa-gRiM]

So I'm in a Java class, and I did all this but the Gpa isnt returning a result, it just returns 0.0 when it gets ran, and for the life of me I cant find the problem, here the code.

import javax.swing.JOptionPane;
public class ShowStudent
{
	public static void main(String[] args)
	{
		Student oneStudent = new Student();
		int showId;
		int showHours;
		int showEarned;
		double showGpa;
		oneStudent.setidNum(Integer.parseInt(JOptionPane.showInputDialog(null, "ID Number: ")));
		oneStudent.setcHours(Integer.parseInt(JOptionPane.showInputDialog(null, "Total Credit Hours Earned: ")));
		oneStudent.setpEarned(Integer.parseInt(JOptionPane.showInputDialog(null, "Total Points Earned: ")));
		showId = oneStudent.getidNum();
		showHours = oneStudent.getcHours();
		showEarned = oneStudent.getpEarned();
		showGpa = oneStudent.getGpa();
		JOptionPane.showMessageDialog(null, "ID Number: " + showId + "\nTotal Credit Hours Earned: " + showHours + "\nTotal Points Earned: " + showEarned 
		+ "\nGPA: " + showGpa);		
	}
}

public class Student
{
    private int idNum;
    private int cHours;
    private int pEarned;
    private double Gpa;
    public int getidNum()
    {
	    return idNum;
    }
    public int getcHours()
    {
	    return cHours;
    }
    public int getpEarned()
    {
	    return pEarned;
    }
    public double getGpa()
    {
        Gpa = cHours/pEarned;
        
	    return Gpa;
    }
    public void setidNum(int showId)
    {
	    idNum = showId;
    }
    public void setcHours(int showHours)
    {
	    cHours = showHours;
    }
    public void setpEarned(int showEarned)
    {
	    pEarned = showEarned;
    }
    public void setGpa(double showGpa)
    {
	    Gpa = showGpa;
    }
}
