这里就把排序算法与面向对象相结合了,很简单!!!!!!
package StructSort_1;
public class MyDate {
public int year;
public int month;
public int day;
@Override
public String toString() {
return year + ", " + month + "," + day;
}
public MyDate(int year, int month, int day) {
this.year = year;
this.month = month;
this.day = day;
}
}
package StructSort_1;
public class Person {
public MyDate brith;
public String name;
public double key;
public Person(String name,MyDate brith, double key) {
this.brith = brith;
this.name = name;
this.key = key;
}
@Override
public String toString() {
return brith + "," + name + ", " + key;
}
}
package StructSort_1;
public class ObjectSort {
public static void main(String[] args) {
Person ps[] = new Person[6];
ps[0] = new Person("Jack", new MyDate(1997, 1, 1), 23.12);
ps[1] = new Person("Tom", new MyDate(1992, 10, 1), -1);
ps[2] = new Person("Rose", new MyDate(1993, 5, 11), 66.6);
ps[3] = new Person("Jerry", new MyDate(1991, 8, 8), 88.8);
ps[4] = new Person("张三", new MyDate(1995, 9, 2), 22);
ps[5] = new Person("王五", new MyDate(2017, 7, 12), 12.12);
print(ps);
bubbleSort(ps);
print(ps);
}
//这里使用的是冒泡排序
public static void bubbleSort(Person ps[]) {
for (int i = 0; i < ps.length - 1; i++) {
for (int j = 0; j < ps.length - i - 1; j++) {
if (ps[j].key > ps[j + 1].key) {// 用关键字的值比较
swap(ps, j, j + 1); // 交换对象的引用
}
}
}
}
private static void swap(Person[] ps, int j, int i) {
Person temp = ps[i];
ps[i] = ps[j];
ps[j] = temp;
}
private static void print(Person ps[]) {
for (Person p : ps) { //增强for循环(只能读不能写)
System.out.println(p);
}
System.out.println("-----------------");
}
}
