如何使用自定義模式在Java中拆分String

Question

我正在嘗試使用String.split("[,\\\\:]");從此字符串獲取位置數據String.split("[,\\\\:]");

String location = "$,lat:27.980194,lng:46.090199,speed:0.48,fix:1,sats:6,";
String[] str = location.split("[,\\:]");

我如何獲得這樣的數據。

str[0] = 27.980194
str[1] = 46.090199
str[2] = 0.48
str[3] = 1
str[4] = 6

感謝您的任何幫助！

Answer 1

如果只想保留數字（包括點分隔符），則可以使用：

String[] str = location.split("[^\\d\\.]+");

您將需要忽略數組中的第一個元素為空字符串。

僅在數據名稱不包含數字或點的情況下才有效。

快速與骯臟：

String location = "$,lat:27.980194,lng:46.090199,speed:0.48,fix:1,sats:6,";
     List<String> strList = (List) Arrays.asList( location.split("[,\\:]"));

    String[] str = new String[5];
    int count=0;
    for(String s : strList){
        try {
            Double d =Double.parseDouble(s);
            str[count] = d.toString();
            System.out.println("In String Array:"+str[count]);
            count++;
        } catch (NumberFormatException e) {
          System.out.println("s:"+s);
        }

    }

        String location = "$,lat:27.980194,lng:46.090199,speed:0.48,fix:1,sats:6,";
        Matcher m = Pattern.compile( "\\d+\\.*\\d*" ).matcher(location);
        List<String> allMatches = new ArrayList<>();
        while (m.find( )) {
            allMatches.add(m.group());
        }
        System.out.println(allMatches);
