drawing shapes program using multiple classes, help me please //interesting
program hierarchy
3 packages and 8 classes
screen-screencoordinate
shapes-point,shape,shapespanel,shapestest
world-bounds,coordiante,coordinate
i am getting the jframe but somehow not getting points on to it.
the following is the source code of classes,
package screen;
public class ScreenCoordinate
{
private int m_x;
private int m_y;
public ScreenCoordinate(int x, int y)
{
this.m_x = x;
this.m_y = y;
}
public int getX()
{
return m_x;
}
public int getY()
{
return m_y;
}
public boolean equals(ScreenCoordinate coord)
{
return false;
}
public String toString()
{
String sc = "X"+getX()+" "+"Y"+getY();
return sc;
}
}

==================================================================
my output should plot the coordinates on the jframe...but i am only getting jframe..anybody help please>
