Super不要在Super构造器中调用覆盖方法

import java.util.Date;

public class Super{
public Super(){
System.out.println("5");
overrideMe();
System.out.println("6");
}
public void overrideMe(){}
}

public final class Sub extends Super
{
private final Date date;
Sub(){
date=new Date();
System.out.println("1");
}

@Override public void overrideMe()
{
System.out.println(date);
}

public  static void main(String[] args)
{
Sub sub=new Sub();
System.out.println("2");
sub.overrideMe();
System.out.println("3");
}
}
