while循环中的最后一行在第二个循环的每次迭代后打印。如何在收到给定命令后打印一次？ package toto.com； 导入java.util.Scanner； 公共类编校者{ 公共静态void main（字符串[]args）{ 扫描仪=新的扫描仪（System.in）； String=scanner.nextLine（）； 双赢=0； 双失=0； 双插座=0； //输入 //芭蕾舞演员 //3 //87 //63 //56 //65 //75 //64 //鲨鱼 //4 //64 //76 //65 //86 //68 //99 //45 //78 //比赛结束 //输出在底部 而（！锦标赛.equals（“锦标赛结束”））{ int matches=Integer.parseInt（scanner.nextLine（））； 插座+=火柴； 对于（int i=0；i点2）{ 韩元++； System.out.printf（“%n比赛%s的名称%d：以%d点获胜。”，i，比赛，点1-点2）； }否则{ 丢失的++； System.out.printf（“%n比赛%s的名称%d：因%d点而丢失。”，i，比赛，点2-点1）； } } System.out.printf（“%n%.2f%%匹配赢%n”+ “%.2f%%matches lost”、（won/receptor）*100、（lost/receptor）*100）；//就我而言，在循环外使用if语句打印它似乎不起作用，因为其中的条件始终为真。 锦标赛=scanner.nextLine（）； } } } //期望输出 //锦标赛芭蕾选手第一场：以24分获胜。 //芭蕾锦标赛第二场：以9分输掉。 //锦标赛芭蕾选手第三场：以11分获胜。 //鲨鱼锦标赛第一场：以12分输掉。 //鲨鱼锦标赛第二场：以21分输掉。 //鲨鱼锦标赛第三场：以31分输掉。 //鲨鱼锦标赛第四场：以33分输掉。 //28.57%的比赛获胜 //71.43%的比赛失败

我把你的问题理解为询问如何在比赛结束后才打印输赢数字。要完成此操作，请在while循环后移动最后的printf语句。那么它只会在你的比赛结束后运行一次

它在for循环中打印统计数据，然后程序继续进行到结束。我更新了我的答案，使游戏统计数据和锦标赛赢/输统计数据之间的区别更加明确。你能确认我的答案中的输出符合你的期望吗？它是无效的。它不会像我上面提到的那样打印最终统计数据（锦标赛赢/输）。还有其他建议吗？这很奇怪，因为它会在我这边打印赢/输统计数据。您能否提供包含上述建议的代码的更新版本？

while (!tournament.equals("End of tournaments")) {
    int matches = Integer.parseInt(scanner.nextLine());
    receptacle += matches;

    for (int i = 0; i < matches; i++) {//TODO redact of needed to 0 and <
        int points1 = Integer.parseInt(scanner.nextLine());
        int points2 = Integer.parseInt(scanner.nextLine());

        if (points1 > points2) {
            won++;
            System.out.printf("%nGame %d of tournament %s: win with %d points.", i, tournament, points1 - points2);
        } else {
            lost++;
            System.out.printf("%nGame %d of tournament %s: lost with %d points.", i, tournament, points2 - points1);
        }

    }

    // Location of line to move from
    tournament = scanner.nextLine();

}
// Location of print statment to move to
System.out.printf("%n%.2f%% matches win%n" +
        "%.2f%% matches lost", (won / receptacle) * 100, (lost / receptacle) * 100); // As far as I'm concerned printing it outside of the loop using if statement doesnt't seem to work because the condition within is always true.
