任意字符串转数字

    String s = "1234wfsdfsdf23()_&*(234785h \\n ufnjikedKL:JFL:>:\"?\":\" ";
    char[] charArray = s.toCharArray();
    StringBuilder n = new StringBuilder(s.length());
    for (char c : charArray) {
        int a = c;
        n.append(a);
    }
    String string = n.toString();
    // 如果可以转Long 太长就不能转
    // Long long1 = Long.valueOf(string);
    // System.out.println(long1);
    System.out.println(string);
