各位大神看看有没有改进的地方

Question

class Squre extends shapeDome{    private int chang;    private int kuan;   public int getChang() { return chang; } public void setChang(int chang) { this.chang = chang; } public int getKuan() { return kuan; } public void setKuan(int kuan) { this.kuan = kuan; } public void girth() { setChang(10); setKuan(5);        int girth =2*(getChang()+getKuan());        System.out.println("周长为"+girth); } public void area() { setChang(10); setKuan(5); int area=getChang()*getKuan(); System.out.println("面积为"+area); } }class Circle extends shapeDome{    private int banjing;    public int getBanjing() { return banjing; }    public void setBanjing(int banjing) { this.banjing = banjing; } public void girth() {    setBanjing(5);    double girth=3.14*getBanjing();     System.out.println("周长为"+girth); } public void area() {    setBanjing(5);    double area=3.14*getBanjing()*getBanjing();    System.out.println("面积为"+area); } }public abstract class shapeDome {   public abstract void girth();   public abstract void area();}public class Initalshap { public static void main(String[] args) {    Squre s=new Squre();    s.getChang();    s.getKuan();    s.girth();    s.area();    Circle c=new Circle();    c.getBanjing();    c.girth();    c.area(); }}

Answer 1

public void area() {

setChang(10);

setKuan(5);

int area=getChang()*getKuan();

System.out.println("面积为"+area);

}

}

可以改为

public void area(int A,int B) {

setChang(A);

setKuan(B);

int area=getChang()*getKuan();

System.out.println("面积为"+area);

}

}

其余类似自己改。还有一点命名长宽用英文吧，不会就下个有道词典，命名规范一点。
