请问各位．这个里面有２个mian()
先从哪个开始执行啊．．．
而且最后有个Abc.main(args);
这句是什么意思啊．
class Abc
{
private String s=new String("Cleanser");
public void append(String a) {s+=a;}
public void dilute(){append("dilute()");}
public void apply(){append("apply()");}
public void scrub(){append("scrub()");}
public void print(){System.out.println(s);}
public static void main(String args[])
{
Abc x=new Abc();
x.dilute();
x.apply();
x.scrub();
x.print();
}
}
public class Cba extends Abc
{
public void scrub()
{
append("Detergent.scrub()");
super.scrub();
}
public void foam()
{
append("foam()");
}
public static void main(String args[])
{
Cba x=new Cba();
x.dilute();
x.apply();
x.scrub();
x.foam();
x.print();
System.out.println("Testing base class:");
Abc.main(args);
}
}

谢谢．虽然　已经猜出来了．
但是不确定
