Posted 2021-01-10 薰衣草

public class Person {

}

 

public class Student extends Person{
    private String name;

    public Student(String name) {
        this.name = name;
    }

    public Student() {
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "Student{" +
                "name=\'" + name + \'\\\'\' +
                \'}\';
    }
}

 泛型类型变量只能调用限定类或限定接口里面的方法
