我定义并且赋值了三个，为啥只输入ZC，而name和age为什么不显示赋值呢？
class person
{
    private int age;
    private String name;
    public void per(int age,String name)
    {
        this.age=age;
        this.name=name;
    }
    public String info()
    {
        return "name:"+name+"\nage:"+age;
    }
}
class teacher extends person
{
     private String zc;
     private int age;
     private String name;
    public void teach(String zc)
    {
      
        super.per(age, name);
          this.zc=zc;
        // TODO 自动生成的构造函数存根
    }
    public String info()
    {
        return "name:"+name+"\nage:"+age+"\nZC:"+zc;
    }
}
public class Clas1 {

    public static void main(String[] args) {
        // TODO 自动生成的方法存根
         teacher t=new teacher();
         t.per(19, "TOM");
         t.teach("高级工程师");
         System.out.println(t.info());
    }

}
