为什么答案是两个in Second class

阅读以下程序，写出输出结果。
class First{
public First(){
aMethod();
}
public void aMethod(){
System.out.println(“in First class”);}
}
public class Second extends First{
public Second(){
super();
aMethod();
}
public void aMethod(){
System.out.println(“in Second class”);
}
public static void main(String[ ] args){
new Second( );
}
