代碼如下:

@Test
    public void test33() {
        String phoneString = "哈哈,13888889999";
        // 提取數字
        // 1
        Pattern pattern = Pattern.compile("[^0-9]");
        Matcher matcher = pattern.matcher(phoneString);
        String all = matcher.replaceAll("");
        System.out.println("phone:" + all);
        // 2
        Pattern.compile("[^0-9]").matcher(phoneString).replaceAll("");
    }

 提取張三，去除數字

復制代碼代碼如下:

@Test
    public void test() {
        // 提取張三 去除數字
        String r_name3 = "張三 13599998888 000000";
        Pattern pattern = Pattern.compile("[\\d]");
        Matcher matcher = pattern.matcher(r_name3);
        System.out.println(matcher.replaceAll("").trim());
    }
