从用户处获取一个字符，并在Java中查找用户给定的字符串中该字符出现的次数

import java.util.Scanner;

public class CharacterCount {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入一个字符串：");
        String inputString = scanner.nextLine();
        System.out.println("请输入要查找的字符：");
        char searchChar = scanner.next().charAt(0);

        int count = countCharacter(inputString, searchChar);
        System.out.println("字符 '" + searchChar + "' 在字符串中出现了 " + count + " 次。");
    }

    public static int countCharacter(String str, char ch) {
        int count = 0;
        for (int i = 0; i < str.length(); i++) {
            if (str.charAt(i) == ch) {
                count++;
            }
        }
        return count;
    }
}
