帮我用java和Typescript设计一个游戏经验等级匹配方法最高100级

下面是一个使用Java和TypeScript设计游戏经验等级匹配方法的示例：

Java代码：

public class GameExperienceMatcher {
    public static int getMatchingLevel(int playerLevel, int opponentLevel) {
        int levelDifference = Math.abs(playerLevel - opponentLevel);
        if (levelDifference <= 5) {
            return 100;
        } else if (levelDifference <= 10) {
            return 90;
        } else if (levelDifference <= 20) {
            return 80;
        } else if (levelDifference <= 30) {
            return 70;
        } else if (levelDifference <= 40) {
            return 60;
        } else if (levelDifference <= 50) {
            return 50;
        } else if (levelDifference <= 60) {
            return 40;
        } else if (levelDifference <= 70) {
            return 30;
        } else if (levelDifference <= 80) {
            return 20;
        } else if (levelDifference <= 90) {
            return 10;
        } else {
            return 0;
        }
    }
}

TypeScript代码：

function getMatchingLevel(playerLevel: number, opponentLevel: number): number {
  const levelDifference: number = Math.abs(playerLevel - opponentLevel);
  if (levelDifference <= 5) {
    return 100;
  } else if (levelDifference <= 10) {
    return 90;
  } else if (levelDifference <= 20) {
    return 80;
  } else if (levelDifference <= 30) {
    return 70;
  } else if (levelDifference <= 40) {
    return 60;
  } else if (levelDifference <= 50) {
    return 50;
  } else if (levelDifference <= 60) {
    return 40;
  } else if (levelDifference <= 70) {
    return 30;
  } else if (levelDifference <= 80) {
    return 20;
  } else if (levelDifference <= 90) {
    return 10;
  } else {
    return 0;
  }
}

这个方法根据玩家和对手的等级差异，返回一个匹配级别（从0到100）。如果等级差异在5之内，返回100级匹配级别，依此类推
