如何拆分java字符串以獲得分隔符“，”上的5個子字符串

Question

我有一個 java 字符串作為服務器的響應["This is my "json response", "jshj" "," "sdjfh,sfjg" ",""Abs, "jshj" ",""Abs, "jshj" ",""Abs, "jshj"",""Abs, "jshj" "]. 我想在分隔符“,”上將字符串拆分為 5 個子字符串，以便我可以將結果存儲到數組中。

預期輸出是：

這是我的“json 響應”，“jshj”“sdjfh,sfjg”“Abs，“jshj”“Abs，“jshj”“Abs，“jshj”“Abs，“jshj”

以下是我的做法：

String arrayGenerated[] =result.replaceAll("[\\[\\]\"]", "").split(__________,5);
        return arrayGenerated;

請建議我應該在拆分部分提到什么。

Answer 1

您可以按照以下步驟進行操作：

public class Main {
    public static void main(String[] args) {
        String resString = "[\"This is my \"json response\", \"jshj\" \",\" \"sdjfh,sfjg\" \",\"\"Abs, \"jshj\" \",\"\"Abs, \"jshj\" \",\"\"Abs, \"jshj\"\",\"\"Abs, \"jshj\" \"]";

        String str = resString.replaceAll("\\[", "").replaceAll("\\]", ""); // Remove [ and ]

        String substrs[] = str.split("\",\""); // Split at ","
        for(int i=0;i<substrs.length;i++)
            substrs[i]=substrs[i].trim(); // Trim each substring
        int li=substrs.length-1; //Index of last substring in the array
        substrs[li]=substrs[li].substring(0,substrs[li].lastIndexOf("\"")).trim(); // In the last String, remove extra " from the end

        for(String substr:substrs)
            System.out.println(substr);
    }
}

輸出：

"This is my "json response", "jshj"
"sdjfh,sfjg"
"Abs, "jshj"
"Abs, "jshj"
"Abs, "jshj"
"Abs, "jshj"

Answer 2

解析服務器響應后，可以使用String.split（“ regular expression”）方法拆分響應。

String a = "[\"This is my \"json response\", \"jshj\" \",\" \"sdjfh,sfjg\" \",\"\"Abs, \"jshj\" \",\"\"Abs, \"jshj\" \",\"\"Abs, \"jshj\"\",\"\"Abs, \"jshj\" \"]";
String arr[] = a.split("\",\"");

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;
import java.util.stream.Stream;

public class Test1222 {
    public static void main(String[]args)
    {
        String fileName = "C:\\\filepath";
        List<String> list = null;
        try (Stream<String> stream = Files.lines(Paths.get(fileName))) {
            list = stream.collect(Collectors.toList()); 
        } catch (IOException e) {
            e.printStackTrace();
        }
        String str = list.get(0);
        String str1 = str.replaceAll("\\[", "").replaceAll("\\]","");

        String[] strArr = str1.split(",");
        List<String> resultArr = Arrays.asList(strArr);
        List<String> result = resultArr.stream().collect(Collectors.toList());

        result.forEach(System.out::println);

    }

}

您可以傳遞服務器響應，然后按如下所示拆分響應，

String str = "[\"This is my \"json response\", \"jshj\" \",\" \"sdjfh,sfjg\" \",\"\"Abs, \"jshj\" \",\"\"Abs, \"jshj\" \",\"\"Abs, \"jshj\"\",\"\"Abs, \"jshj\" \"]";

str = str.replaceAll("\\[", "").replaceAll("\\]", ""); // To remove []

List<String> list = Arrays.asList(str.split(",")); // Simply separate words by comma to a list that you can iterate

for (Iterator<String> iterator = list.iterator(); iterator.hasNext();) {
    String next = iterator.next();
    System.out.println(next);
}

如果您需要從服務器響應中刪除雙引號，則可以使用以下語句，

str.replaceAll("\"", "")
