编译调试的一个奇怪错误！

[vclongking]

wtk1.0+J2ME 写的一段代码，最后编译出现以下错误提示：
D：\JAVA\J2ME\wtk1.0.4\apps\Man\src\gameScreen.java:5: gameScreen is not abstract and does not override abstract method run() in java.lang.Runnable

public class gameScreen extends Canvas implements Runnable

^

D:\JAVA\J2ME\wtk1.0.4\apps\Man\src\Man.java:5: Man is not abstract and does not override abstract method startApp() in javax.microedition.midlet.MIDlet

public class Man extends MIDlet implements CommandListener

com.sun.kvem.ktools.ExecutionException

Build failed

不知是什么原因？望高手解释一下

[四十三号]

gameScreen is not abstract and does not override abstract method run() in java.lang.Runnable
Man is not abstract and does not override abstract method startApp() in javax.microedition.midlet.MIDlet

自己翻译一下。

实现了Runnable接口，但是没有覆盖他的run()方法。

[很久以前飞]

实现了Runnable 但没有覆盖run()方法；
public class gameScreen extends Canvas implements Runnable {

public void run(){

}

}

[Quote=引用 3 楼 k498279797 的回复:]
实现了Runnable 但没有覆盖run()方法；
public class gameScreen extends Canvas implements Runnable {

public void run(){//就是这样,你要加这个方法上去

}

}

[誰伴我闖荡]

如上面所说

[Sodino]

两个错误：
1.gameScreen is not abstract and does not override abstract method run() in java.lang.Runnable

public class gameScreen extends Canvas implements Runnable

要自己实现 run()方法

2.Man is not abstract and does not override abstract method startApp() in javax.microedition.midlet.MIDlet

public class Man extends MIDlet implements CommandListener

要自己实现 startApp()方法
