import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;


public class URLCleaning {
    public static void main(String[] args) throws IOException {
        String ur1;
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        System.out.print("输入原始ur1：");
        ur1 = br.readLine();
        
        // 清洗网址的空格字符
        ur1 = ur1.replace(" ","");
        // 清洗网址中的$符号
        ur1 = ur1.replace("$","");
        // 清洗网址中的%符号
        ur1 = ur1.replace("%","");
        // 清洗网址中的#符号
        ur1 = ur1.replace("#","");

        System.out.println("清洗后的ur1：" + ur1);
