Java中的清洗网站中的乱码

 

代码如下： public class URL {
    public static void main(String[] args)throws IOException {
        String url;
        String strGarbage;//垃圾字符串
        BufferedReader br =new BufferedReader(new InputStreamReader(System.in));         System.out.print("输入原始url:");
        url = br.readLine();
        System.out.println("输入垃圾字符串：");
        strGarbage = br.readLine();         //遍历垃圾字符串
        for (int i = 0; i < strGarbage.length(); i++){
            //逐个清洗垃圾字符串里的每个字符
            url = url.replace(String.valueOf(strGarbage.charAt(i)),"");
        }
        System.out.println("清洗后的url:" + url);         //清洗网址的空格字符
        url = url.replace("","");
        //清洗网址中的$符号
        url = url.replace("$","");
        //清洗网址中的&符号
        url = url.replace("&","");
        //清洗网址中的#符号
        url = url.replace("#","");         System.out.println(("清洗后的url:" + url));     } }
