java - 我的Java程序正在创建27个无效错误

Question

当我运行这些行的Java代码时，它给了我27条错误，但不是实际错误

for(int counter = 0;counter<teamName.size();counter++)
  {
  System.out.print((counter + 1) + "   " +  teamName.get(counter) + "   " + (aLeaderboard.get(counter)).getGamesPlayed() + "   " + (aLeaderboard.get(counter)).getHomeWins() + "   " +  (aLeaderboard.get(counter)).getHomeDraws() + "   ");
  System.out.println();
  }

aLeaderboard是一个带有自定义类Leaderboard的ArrayList。它是20长，teamName也是一个ArrayList，它是20长。

ArrayList<Leaderboard> aLeaderboard = new ArrayList<Leaderboard>();

它产生这些错误:

teamName包含20个都是单个单词的字符串。

Answer 1

这段代码在方法之外吗？

尝试用以下代码替换当前代码:

public static test() {
for(int counter = 0;counter<teamName.size();counter++)
  {
  System.out.print((counter + 1) + "   " +  teamName.get(counter) + "   " + (aLeaderboard.get(counter)).getGamesPlayed() + "   " + (aLeaderboard.get(counter)).getHomeWins() + "   " +  (aLeaderboard.get(counter)).getHomeDraws() + "   ");
  System.out.println();
  }
}
