详解Java继承中属性、方法和对象的关系

public class FieldDemo {   public static void main(String[] args){     Student t = new Student("Jack");     Person p = t;//父类创建的引用指向子类所创建的对象      System.out.println(t.name+","+p.name);     System.out.println(t.getName()+","+p.getName());   }  } class Person{   String name;   int age;   public String getName(){     return this.name;   } } class Student extends Person{   String name; // 属性和父类属性名相同，但在做开发时一般不会和父类属性名相同！！    public Student(String name){     this.name = name;     super.name = "Rose"; // 为父类中的属性赋值    }   public String getName(){     return this.name;   } }
