大家好，小弟是新人，想大家帮一下看看我这程序哪里出错了！

class Person
{
    private int age;
    private String name;
    public static void Person(int age, String name )
    {
        if(age>=0&&age<120)
        {
        this.age=age;
        this.name=name;
        }
    }
   
}
class Students extends Person
{   super(age,name);
    void study()
    {
        System.out.println(name+"is studying and his age is "+age);
    }
}
class Worker
{
    super(age,name);
    void work()
    {
        System.out.println(name+"is working and his age is "+age);
    }

}
class ExtendsExam
{
    public static void main(String[] args)
    {
        Student p=new person();
        Worker  t=new Worker();
        p.age=20;
        p.name="lixiangzheng";
        t.age=30;
        t.name="chenglong";
        p.study();
         t.work();
    }
}




编辑器上显示的错误是：
extendsexam.java:17: 错误: 需要';'
        void study()
                    ^
extendsexam.java:28: 错误: 需要<标识符>
class
