Java-调用抽象类中指定参数的构造方法

abstract class person

 private String name;
 private int age;
 public person(String name,int age)
 {
         this.setage(age);
         this.setname(name);
 }

 }

 }
 public void setname(String name)
 {
  this.name=name;
 }
 public String getname()
 {
  return this.name;
 }
 public abstract String getinfo();
}
class student extends person
{

 }
}
