java——接口的实现

/**

 */
interface  java_jiekou1
{
    String name = "张三";
    int age = 25;
    String occupation = "学生";
    public abstract String talk();
}
class Student5 implements java_jiekou1
{
    //覆写talk（）方法
    public String talk()
    {
        return "学生——》姓名："+this.name+"年龄："+this.age+"职业："+this.occupation;
    }
}

/**
 * Created by xabcd on 2019/2/16.
 */
public class test_jiekou1
{
    public static void main(String[] args)
    {
        Student5 s =new Student5();
        System.out.println(s.talk());
    }
}





结果：
学生——》姓名：张三年龄：25职业：学生
