Using actionListeners to move a line 20 pixels in every direction

Question

I'm trying to create an actionListener for a button. I need to be able to click on the button and move a line 20 pixels in every direction. But i have no idea how to do this. I'm supposed to have an object in my ColoredLine class that allows for me to use with the ActionListener class but I don't even know what that means. Here is my ButtonForLine class that implements listener and my ColoredLine class that gives the original line.
public class ButtonForLine implements ActionListener {
          public int q;
          public int w;
          public int e;
          public int r;
          public Color color;     
public void actionPerformed ( ActionEvent e ) {
     ColoredLine move= new ColoredLine;
public ButtonForLine( ) {
     q = (left + 20);
     w = (top + 20);
     e = (right + 20);
     r = (bottom + 20);
public class ColoredLine implements Drawable {          //creates all instance fields for entire class
     private int left;          //colored lines store the positions of their left, top, right, bottom, and color
     private int top;          // of their lines. It also stores the same positions for the twin lines.
     private int right;
     private int bottom;
     private Color color;
     private int q;
     private int w;
     private int e;
     private int r;
Creates a colored line. It calls for the new positons of the color swatch.
@param x1 the top left of the line
@param y1 the top of the line
@param x2 the bottom right of the line
@param y2 the bottom of the line
@param c the color of the line
public ColoredLine( int x1, int y1, int x2, int y2, Color c) {
     left = x1;
     top = y1;
     right = x2;
     bottom = y2;
     color = c;
Draw a colored line using a graphics context
@param g the graphics context used to draw the line
public void draw( Graphics2D g ) {
     g.setColor( color );
     g.drawLine( left, top, right, bottom );
public ColoredLine move() {
     q= (left + 20);
     w= (top + 20);
     e= (right + 20);
     r= (bottom + 20);
     ColoredLine moved = new ColoredLine( q, w, e, r, color );
     return moved;
}
