1、单词分析

找出单词字符串中出现次数最多的字母

import java.util.Scanner;
// 1:无需package
// 2: 类名必须Main, 不可修改

public class Main {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        //在此输入您的代码...
        String input = scan.nextLine();
        int[] letters = new int['z'-'a'+1];
        
        for(int i = 0; i < input.length(); i++) {
          ++letters[input.charAt(i) - 'a'];
        }
        int max = 0;
        int index = 0;
        for(int i = 0; i < letters.length; i++) {
          if(max < letters[i]) {
            max = letters[i];
            index = i;
          }
        }
        System.out.println((char)('a' + index));
        System.out.println(max);
        scan.close();
    }
}
