分析程序的输出

写出下面代码的输出结果，为什么？

public class Test2{    static int i=5;    public static void main(String[] args){        Father father = new Child();        father = new Child();        System.out.println( (change()==3)?i+15:i+10.0 );    }    public static int change(){        if(i==5){            i = i+10;        }        return i = i/5;    }}class Father{    public Father(){        System.out.println("father...");    }    static{        System.out.println("father2");    }}class Child extends Father{    public Child(){        System.out.println("child...");    }    static{        System.out.println("child2");    }}/*输出结果：father2child2father...child...father...child...18.0*//*      ?号表达式中，冒号两边的表达式的数据类型必须一致 (若不同则自动向高精度靠齐)    int x=3,y=1;    System.out.println( (x==3)?y+1:y+10 ); //结果：2    System.out.println( (x==3)?y+1:y+10.0 ); //结果：2.0*/
