    public void show(){
        if((age>=0&&age<18)||(age>60)){
            System.out.println( name +"'s age is:"+ age +",ticket:free.");
        }
        if(age>=18&&age<=60){
            System.out.println( name +"'s age is:"+ age +",ticket:20$.");
        }
        if(age<0){
            System.out.println( name +"'s age not be less than 0.");
        }
    }

    public static void main(String[] args){
        People people=new People();
        System.out.println("please input name");
        Scanner scan1 = new Scanner(System.in);
        people.name=scan1.next();
        System.out.println("please input age");
        people.age=scan1.nextInt();
        scan1.close();
        people.show();
