<p><b><span class="article">2.7.2 ClickMe Applet中的對象</span></b></p>
<p class="article"> 在這個applet中有許多對象。兩個最明顯的是：applet本身和紅點。</p>
<p class="article"> 瀏覽器在包含applet的HTML代碼中碰到applet標簽的時候就創建了applet對象。這個applet標簽從創建applet對象的地方提供類的名字。在本例子中，這個類的名字為ClickMe。</p>
<p class="article"> ClickME.applet將創建一個對象來在屏幕上畫出點。每次你在applet中點擊鼠標的時候，applet就將通過改變對象的x和y坐標來移動紅點。這個點不是自己畫出來的，它是applet畫出的，它是根據包含在點對象中的信息畫出的。</p>
<p class="article"> 除了前面兩個明顯的對象，另外還有一些看不見的對象呢。有代表三種顏色（黑、白、紅）的三個對象以及代表點擊鼠標的用戶動作的事件對象等等。</p>
