排序高分。與分揀時間輸入Diffuculties

Question

我有diffuculties排序輸入，我想它按最低時間先排序。我是新來的java所以我不知道這麼多我已經做了一個數字遊戲，但我無法設法排序的最低時間在這裏是我迄今爲止做的高分。

import java.util.*; 

public class teeeeeeeeeeeeeeeeeeeeeeeeeeeeeeest { 

    private static void start() throws IOException {

     System.out.println("Hello and welcome to this guessing game" + 
       "\nStart guessing it's a number between 1 and 1000:");

      System.out.print("\nEnter your guess: "); 
      gissning = input.nextInt(); 
      försök++; 



      if (gissning == number){ 
       long endTime = System.currentTimeMillis(); 
       long gameTime = endTime - startTime; 
       System.out.println("Yes, the number is " + number + 
         "\nYou got it after " + försök + " guesses " + " times in " + (int)(gameTime/1000) + " seconds.");

      else

Answer 1

創建一個包含所有評分，時間和其他詳細信息的值對象。創建一個比較器，比較兩個持有者之間的組件。分類可以通過用比較器創建一套持有人來實現。

如果您希望按其他順序排列，請根據需要更新比較器。

Holder { 
    long time; 
    int score; 

    String name; 
} 

Comparator<Holder> { 
    int compare(Holder holder, Holder other){ 
     int result = holder.time - other.time; 
     if(0 == result){ 
      result = holder.score - other.score; 
     } 
     return result; 
    } 
}
