System.out.println(saver.getYLiXi());
}
}
這是我的原代碼

你試下看這個
public class SavingAccount {private static final int MONTH_NUMBER = 12;private double nlxi;//存儲年利率private double cke; //存儲存款額public void setCKE(double cke) {this.cke = cke;}public double getCKE() {return this.cke;}public void setNLiXi(double nlxi) {this.nlxi = nlxi;}//提供計算年利息的方法public double getNLiXi() {return cke * nlxi;}//提供月利息的方法public double getYLixi() {return this.getNLiXi() / MONTH_NUMBER;}public static void main(String[] args) {SavingAccount saver = new SavingAccount();double cke = 3000.0D;double nlixi = 0.03D;saver.setCKE(cke);saver.setNLiXi(nlixi);System.out.println("存儲存款額: " +cke+ "存儲年利率:" +nlixi);System.out.println("年利息: " +saver.getNLiXi());System.out.println("月利息: " +saver.getYLixi());}}複製代碼
