急求!java面向对象程序设计定义三个对象 太阳,蚂蚁,树,向日葵 实现随着从日出到日落时蚂蚁,树,向日葵有规律的变化过

叫Sun 重写了一下， 可以输出 import java.util.logging.Level; import java.util.logging.Logger; public class Sun { public static int hh = 7; public static int mm = 0; public static int ss = 0; public static int angle = 0; Tree a; Ant b; SunFlower c; Sun(){ a = new Tree(); b = new Ant(); c = new SunFlower(); while(true){ try { Thread.sleep(1);//1000毫秒，秒加一 } catch (InterruptedException ex) { Logger.getLogger(Sun.class.getName()).log(Level.SEVERE, null, ex); } addTime(); } } public void addTime(){ while(hh <= 19){ ss++; if(ss == 60){ mm++; ss = 0; } if(mm == 60){ hh++; mm = 0; } addAngle();//测试时间 } } public void addAngle(){ if(((hh == 9)||(hh == 11)||(hh == 13)||(hh == 15)||(hh == 17)||(hh == 19))&&(mm == 0)&&(ss == 0)){ // 9 11 13 15 17 19 angle += 30; //若为 9 11 13 15 17 19 角度加30 a.addHeight();//树高度加0.1 new Ant(); //new一只蚂蚁，蚂蚁计数加一 c.faceOfSun(angle); System.out.println(hh); System.out.println(angle); System.out.println(Ant.count); System.out.println(a.height); } } public static void main(String ars[]){ new Sun(); } } class Ant { public static int count = 0; Ant(){ count++; } } class Tree { public double height = 1; public void addHeight(){ height += 0.1; } } class SunFlower { private int angle = 0; public void faceOfSun(int angle){ this.angle = angle; } }

我运行的时候是没有问题的，你的Sun 建类的时候 首字母小写了......我的是大写的...
