不知道哪里错了，请大神帮忙指出

public class jicheng {
   public static void main(String args[]){
       rabbit b1=new rabbit("兔子");
       tiger b2=new tiger("老虎");
       b1.print();
       b1.eat();
       b1.sleep;
       System.out.println("");
       b2.print();
       b2.eat();
       b2.sleep();
   }

}
class animal{
   protected String name;
   public void eat(){
       System.out.println("吃啊");
   }
   public void sleep(){
       System.out.println("睡觉");
   }
}
class rabbit extends animal{
   public rabbit(String name){
       this.name=name;
   }
   public void eat(){
       System.out.println("吃草");
   }
   public void sleep(){
       System.out.println("睡觉");
   }
}
class tiger extends animal{
   public tiger(String name){
       this.name=name;
   }
   public void eat(){
       System.out.println("吃肉");
   }
   public void sleep(){
       System.out.println("睡觉");
   }
}
