  • I have created Image by “grawImage” in applet and all the image(52 playing cards) is displaying and its moving around inside the applet but all the cards shows in a bunch when I am drage on card its shown below of the above card, so I want that when I dragged any one card in the bounch of 52, this gragable card should be shown, its not showing, top most card is showing, because its on top.
    Please help me.
    my code is-
    CardDemo.java

    package com.progresso;

    import java.awt.*;
    import java.awt.event.*;

    import javax.imageio.ImageIO;
    import javax.swing.*;
