從字符串中獲取引號之間的值 - Java

Question

如何從下面的字符串中獲取引號之間的值：

實際上，在下面每個字符串的末尾，都會在引號中附加不同的參數：

Connect to Database to get data of student severity "low" priority "minor"

Connect to System API to get details severity "moderate" priority "medium"

結果必須是：

severity = low
priority = minor

severity = moderate
priority = medium

Answer 1

您可以使用正則表達式，如下所示：

String string = "Connect to Database to get data of student severity \"low\" priority \"minor\"";
Pattern pattern = Pattern.compile("severity \"(.*)\" priority \"(.*)\"");
Matcher matcher = pattern.matcher(string);
if (matcher.find()) {
    String severity = matcher.group(1);
    String priority = matcher.group(2);
}

Answer 2

簡芯java：

         String word =  "Connect to Database to get data of student severity \"low\" priority \"minor\"";
         String [] wordArray = word.split(" ");
         
         String severity = "", priority = "";
         for(int i=0; i<wordArray.length; i++) {
             if(wordArray[i].contains("severity")) {
                 severity = wordArray[i+1];
             }
             
             if(wordArray[i].contains("priority")) {
                 priority = wordArray[i+1];
             }
         }
         System.out.println(severity +" "+priority);

Answer 3

實現這一目標的最簡單方法是在每個"處拆分文本並獲取第二項和第四項：

String string = "Connect to Database to get data of student severity \"low\" priority \"minor\"";
String[] arr = string.split("\"");
String severity = arr[1];
String priority = arr[3];

請注意，這種方式不能防止錯誤輸入。
