【P1223 排队接水】【Java】【通过改写Comparator类中的compare方法实现对引用数组的排序】

package myPackage;
import java.util.Scanner;
import java.util.Arrays;
import java.util.Comparator;
class People{
	int n;
	double t;
	People(int n,double t){
		this.n=n;
		this.t=t;
	}
}
public class Main {
	static double sum=0;
	public static void main(String[]args) {
		Scanner in=new Scanner(System.in);
		int N=in.nextInt();
		People[]p=new People[N];
		for(int i=0;i comp = new Comparator() {

			@Override
			public int compare(People o1, People o2) {
				// TODO Auto-generated method stub
				if(o1.t>o2.t) {
					return 1;
				}else if(o1.t 
通过改写Comparator类中的compare方法实现对引用数组的排序步骤： 
Ⅰ.创建Comparator类的对象： 
Comparator comp = new Comparator() {

		};
 
Ⅱ.改写Comparator类中的compare方法： 
升序：
 o1.x>o2.x:return 1
 o1.x 降序：
 o1.x o1.x>o2.x:return -1
 
Comparator comp = new Comparator() {

			@Override
			public int compare(People o1, People o2) {
				// TODO Auto-generated method stub
				if(o1.t>o2.t) {
					return 1;
				}else if(o1.t 
Ⅲ.用创建的对象调用Arrays.sort方法： 
Arrays.sort(p, comp);
