Java编写程序,从字符串”want you to konw one thing”中统计出字幕”n”的出现次数

可以使用Java中的字符串方法 `charAt()` 遍历字符串并判断每个字符是否为字母 "n"，然后统计出现次数。

以下是实现代码示例：

public class CountLetter {
    public static void main(String[] args) {
        String str = "want you to know one thing";
        int count = 0;
        for (int i = 0; i < str.length(); i++) {
            if (str.charAt(i) == 'n') {
                count++;
            }
        }
        System.out.println("字母 n 出现的次数为：" + count);
    }
}

输出结果为：

字母 n 出现的次数为：3

你好，下面是 Python 代码实现：

string = "want you to know one thing"
count = 0

for char in string:
    if char == 'n':
        count += 1

print("字母 n 出现的次数为:", count)

输出结果为：

字母 n 出现的次数为: 3
