我在一个框架中绘制了两个字符串的简单Java应用程序的一部分.渲染第一个字符串,但第二个字符串不渲染.

import java.awt.*;
//Begin troublesome section    
class NewFrame extends Frame {

  public void paint (Graphics g)
  {
    g.drawString ("Foo", 70, 70);
  }

 public void paint2 (Graphics g)
  {
    g.drawString ("Bar", 600, 600);
  }

}
//End troublesome section
public class FooBar {

  public static void main (String[] argv)
  {
    NewFrame nf = new NewFrame ();

    nf.setTitle ("Foo Bar");
    nf.setResizable (true);
    nf.setBackground (Color.cyan);
    nf.setSize (700, 700);

    nf.setVisible (true);
  }
}

有问题的代码部分是所谓的"麻烦部分".

当一段文字徘徊时,我试图让DIV掉落.这是原始效果,这个:

var $dropDiv = $('#dropDiv');
$('#holder p').on('hover', function () {
    // Get position of clicked div
    var offset = $(this).offset();

    // Get dimensions of said div
    var h = $(this).outerHeight();
    var w = $(this).outerWidth();

    // Get dimensions of dropping div
    var dh = $dropDiv.outerHeight();
    var dw = $dropDiv.outerWidth();

    // Determine middle position
    var initLeft = offset.left + ((w / 2) - (dw / 2));

    // Animate drop
    $dropDiv.css({
        left: initLeft,
        top: $(window).scrollTop() - dh,
        opacity: 0,
        display: 'block' …
