这个JAVA代码谁能帮我加个注释
我是学VB的,谁能帮我给每行加个注释
最好能每行加个注释,谢谢
package cn;
import javax.jws.WebService;
import org.opensolaris.os.dtrace.*;
import java.io.*;
@WebService()

public static void start() {

Consumer consumer = new LocalConsumer();
consumer.addConsumerListener(new ConsumerAdapter() {
public void dataReceived(DataEvent e) {
writefile(e.getProbeData().toString());
writeXMLFooter();
}
});
try {
consumer.open();
consumer.compile(f);
consumer.enable();
consumer.go();
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}
}

放错地方了，放去java版吧

只能写这么多了,别的也不太懂了,哪位标注一下,学习一下!

请楼主先自己读一读，如果一行都读不明白，建议先了解一下基础知识，看看书，然后再返回来看。不必勉强。
