一曝十寒
TA貢獻13條經驗 獲得超2個贊
public void area() {
setChang(10);
setKuan(5);
int area=getChang()*getKuan();
System.out.println("面積為"+area);
}
}
可以改為
public void area(int A,int B) {
setChang(A);
setKuan(B);
int area=getChang()*getKuan();
System.out.println("面積為"+area);
}
}
其余類似自己改。還有一點命名長寬用英文吧，不會就下個有道詞典，命名規范一點。
