声明一个Student类(成员变量id,name)实现Comparable接口,然后重写compareTo()方法, publicclassStudentimplementsComparable<Student>{privateintid;privateString name;@OverridepublicintcompareTo(Student o){if(this.id < o.id)return-1;elseif(this.id > o.id)return1;elsereturn0; }//getter setter ...//to...
单字段排序 下面是一个示例,演示了一个自定义类Person实现了Comparable接口,并使用compareTo方法按照年龄进行排序: public class Person implements Comparable<Person> { private String name; private int age; // 构造函数、getter 和 setter 方法省略 @Override public int compareTo(Person other) { // 按照年龄...
public int compareTo(Items o) { int result = 0; //按照生产时间降序 result = - this.pubTime.compareTo(o.pubTime); if(0==result){//如果生产时间相同 就按照销售量升序排列 result = this.hits-o.hits; if(0==result){//如果销售量相同 按照名字降序排列 result = - this.title.compareTo(o...
publicinterfaceComparable<T>{intcompareTo(Tt);} compareTo方法的通用约定与equals相似: 将此对象与指定的对象按照排序进行比较。 返回值可能为负整数,零或正整数,因为此对象对应小于,等于或大于指定的对象。 如果指定对象的类型与此对象不能进行比较,则引发ClassCastException异常(类转换异常)。
