Moving a graphic object in Java

trentreznor -  
 soso -
Does anyone have an idea on how to move a graphical object (type: I actually don't know) with the mouse?
The goal is to represent multiple objects, each having a name, using the mouse (to represent a graph, actually) and to

arrange them with the mouse.
Drawing is not a problem (with Canvas), but then I don't see how to move it with this method and I don't see another way.

    Hello, I have a problem, I want to draw a network model (or graph with vertices and edges) using Java.
    Can you please help me? I would like an example of code to get started.
    Thank you.

        I have the same problem and I tried with this program but I don't know how to specify the distance values between the vertices and how to draw the triangles of the arrows?
        import java.awt.*; // import class Graphics
        import javax.swing.*; // import package javax.swing
        import java.util.*;
        import java.awt.Graphics;
        import javax.swing.JFrame;
        import javax.swing.JPanel;
        public class po extends JPanel { int []corX;
        int[] corY;int i;
        public po(){
        corX=new int[9];
        corY=new int[9];
        Random r=new Random();

        for (int i=0;i<7;i++){
        corX[i]=r.nextInt(600);//chooses a number from 1 to 600 for the i-th case
        corY[i]=r.nextInt(400) ;
        System.out.println ("cox["+i+"]="+ corX[i]);
        System.out.println ("coy["+i+"]="+ corY[i]);
        }}
        public void paint(Graphics g)
        {
        for (int i=0;i<7;i++){
        g.setColor(Color.white);
        g.fillOval(corX[i],corY[i],30,30);
        g.setColor(Color.blue);
        g.drawString(""+i,corX[i]+15,corY[i]+15);
        }
        g.setColor(Color.white);
        for(int i=0;i<6;i++)
        { g.drawLine(corX[i]+30,corY[i]+15,corX[i+1]+30,corY[i+1]+15);
        // Polygon triangle = new Polygon(new int[] {corX[i+1]+30,corX[i+1]+40,corX[i+1]+50},new int[] {corY[i+1]+30,corY[i+1]+20,corY[i+1]+30},3);
        //g.drawPolygon(new int[] {corX[i+1]+30,corX[i+1]+30,corX[i+1]+50},new int[] {corY[i+1]+15,corY[i+1]+40,corY[i+1]+50},3);
        } }
        public static void main (String[] args) {
        JFrame frame = new JFrame();
        frame.setBackground(Color.black);
        frame.getContentPane().add(new po());
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(200,200);
        frame.setVisible(true);
        }
        }
