eclipse3.6调试j2me,控制台无法输出？？
源代码：
package package1;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;
public class Succ extends MIDlet {
public Succ() {
// TODO Auto-generated constructor stub
System.out.println("asdf");
}
protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
// TODO Auto-generated method stub
}
protected void pauseApp() {
// TODO Auto-generated method stub
}
protected void startApp() throws MIDletStateChangeException {
// TODO Auto-generated method stub
System.out.println("asdf");
}
}
正确的运行结果就该是：两行asdf,但控制台就只有正在通过存储根 C:\Users\Administrator\j2mewtk\2.5.2\appdb\temp.MediaControlSkin27 来运行，（我的wtk是安装在g盘的）还就是wtk上的按键是不能点击的，郁闷！之后我就MIDPlet菜单下点暂停后恢复（控制台还是没反应），wtk按键就可以点击了，但不管点击哪个键控制台都会有异常

请高手帮个忙，不胜感激！！
我测试了 各种ok eclipse 重新安装下吧
这个是内存分配的异常，很常见的，说明你没有分配内存。不过程序的代码没有任何问题，也很简单。你安装的有问题吗？WTK要是和JDK绑定的?你有没有绑定？重新安装一下吧~本回答被网友采纳
