為什么只執(zhí)行了靜態(tài)初始化代碼塊？沒有執(zhí)行非靜態(tài)初始化代碼塊？
package?newprac;
public?class?Static?{
String?match;//聲明String型變量name
String?time;//聲明char型變量sex
static?String?score;//聲明整型變量age
//通過構(gòu)造方法賦值變量name
public?Static(){
?match?=?"football?match";
?System.out.println("比賽"+match);
}
{
?time?=?"02:00";
?System.out.println("時間"+time);
}
static{
?score?=?"2:1";
?System.out.println("比分"+score);
}
public?static?void?main(String[]?args){
}
}輸出結(jié)果：
比分2：1

在main函數(shù)中 ?構(gòu)建一個方法 ? Static bf=new Static（）;
然后調(diào)用它就可以了 ? ? ? ? ? ? ? ? ? ?bf.Static（）；

main函數(shù)里面沒有建立對象
