求一个java编程高手帮忙啊

实现一个输入程序 接受从键盘读入的字符串 当字符串中所含字符个数少于程序设定的上限时 输出这个字符串 否则抛出mystringexceptionl异常 在异常处理中要求重新输入新的字符串或中断程序运行

Answer 1

import java.util.Scanner;

public class Du {

public static void main(String[] args) throws MyStringException {
Scanner scanner = new Scanner(System.in);
final int limit = 15;//上限

do{
System.out.print("Please input some string less than " + limit + ":");
String input = scanner.nextLine();

if(input.length() > limit){
throw new MyStringException("Too long!The string should be less than " + limit);
}else{
System.out.println(input);
}

}while(true);

}

}

class MyStringException extends Exception{

public MyStringException(String string) {
super(string);
}

}

Please input some string no less than 15:01234567890123456
Exception in thread "main" MyStringException: Too long! The string should be less than 15
at Du.main(Du.java:14)

追问
