[编程入门]自定义函数之字符串拷贝-Java

解题思路:都写在注释里了...........

注意事项:

参考代码:

public static void main(String[] args) {  

Scanner in = new Scanner(System.in);

int n = in.nextInt();      //输入字符串的长度n

String x = in.nextLine(); //清除缓冲区的字符(详情引用此博客https://blog.csdn.net/include_645829461/article/details/88045961)

String a = in.nextLine();//读取字符串

int m = in.nextInt(); //从第m个之后开始读取

if(a.length()==n) {

System.out.println(a.substring(m-1));   // 题目要求第m个开始读起,故而m-1.

}

}

}
