排序高分。 分拣时间输入的差异

我有分类输入的困难，我希望它先按最低时间排序。 我是java的新手，所以我不知道这么多，我已经做了一个猜数字游戏，但我无法在最低时间排序高分，这是我到目前为止所做的。

import java.io.*; import java.util.*; public class teeeeeeeeeeeeeeeeeeeeeeeeeeeeeeest { private static void start() throws IOException { int number = (int) (Math.random() * 1001); BufferedReader reader; reader = new BufferedReader(new InputStreamReader(System.in)); Scanner input = new Scanner(System.in); String scorefile = "p-lista_java"; int försök = 0; int gissning = 0; String namn; String line = null; String y; String n; String val ; String quit = "quit"; System.out.println("Hello and welcome to this guessing game" + "\nStart guessing it's a number between 1 and 1000:"); long startTime = System.currentTimeMillis(); while (true){ 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."); System.out.print("Please enter your name: "); namn = reader.readLine(); try { BufferedWriter outfile = new BufferedWriter(new FileWriter(scorefile, true)); outfile.write(namn + " " + försök +"\t" + (int)(gameTime/1000) + "\n"); outfile.close(); } catch (IOException exception) { } break; } if( gissning  1000 ){ System.out.println("Stupid guess! I wont count that..." ); --försök; } else if (gissning > number) System.out.println(" Your guess is too high"); else System.out.println("Your guess is too low"); } try { BufferedReader infile = new BufferedReader(new FileReader(scorefile)); while ((line = infile.readLine()) != null) { System.out.println(line); } infile.close(); } catch (IOException exception) { } System.out.println("Do you want to continue (Y/N)?"); val=reader.readLine(); if ((val.equals("y"))||(val.equals("Y"))){ teeeeeeeeeeeeeeeeeeeeeeeeeeeeeeest.start(); } else System.out.print("Thanks for playing"); System.exit(0); } }

创建一个值对象，其中包含您的所有评分，时间和其他详细信息。 创建一个比较器，比较其中两个持有者之间的组件。 可以通过使用比较器创建一组持有者来实现分类。

如果您希望按其他顺序排序其他属性，只需根据需要更新比较器。

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