RK3568 Android14 调试 RTL8211F 千兆以太网 (RGMII) 调试 RTL8211F 的核心在于：确认地址（看电阻贴片情况）和搞定延时（配置 rgmii-id 或微调 delay 值）。一旦这两点对上了，RK3568 的千兆网络就能稳定运行。希望这篇结合原理图的实战记录能帮到你！阅读详情

public class Student implements Comparable<Student> {
String name;
int age;

public Student() {
super();

}
public Student(String name, int age) {
super();
this.name = name;
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}

@Override
public int compareTo(Student s) {
// 我歌
int num = this.age-s.getAge();
int num2 = num==0?this.name.compareTo(s.getName()):num;
return num2;
}

}
