個(gè)人見(jiàn)解：static int sum，既然sum是靜態(tài)的，那么就不應(yīng)該依賴(lài)于field--int score2（你說(shuō)的“動(dòng)態(tài)變量”）。
public?class?HelloWorld?{
????//?定義靜態(tài)變量score1
????static?int?score1?=?86;
????//定義動(dòng)態(tài)變量score2
????int?score2?=?92;
????//定義靜態(tài)變量sum，并且求和,score2通過(guò)對(duì)象定義的靜態(tài)變量求和
????static?int?sum;
????public?static?void?main(String[]?args)?{
????????HelloWorld?scoreSum?=?new?HelloWorld();
????????sum?=?score1?+?scoreSum.score2;
????????System.out.println("總分："?+?sum);
????}
}
