如何将CSV数据高效转换成Java HashMap的键值对？

本文共计278个文字，预计阅读时间需要2分钟。

javapublic class Example { public static void main(String[] args) { String csvFile=test.csv; try (BufferedReader br=new BufferedReader(new FileReader(csvFile))) { String line; while ((line=br.readLine()) !=null) { String[] values=line.split(,); for (String value : values) { int key=Integer.parseInt(value); System.out.println(key); } } } catch (IOException e) { e.printStackTrace(); } }}

嗨我有一个csv叫做test.csv。我试图逐行读取csv并将值转换为哈希键值对。这是代码-publicclassExample{publicsta

嗨我有一个csv叫做test.csv。我试图逐行读取csv并将值转换为哈希键值对。这是代码-

public class Example {

public static void main(String[] args) throws ParseException, IOException {

// TODO Auto-generated method stub

BufferedReader br new BufferedReader(new FileReader("test.csv"));

String line null;

HashMap map new HashMap();

while((linebr.readLine())!null){

String str[] line.split(",");

for(int i0;i

String arr[] str[i].split(":");

map.put(arr[0], arr[1]);

}

}

System.out.println(map);

}

}

csv文件如下-

1,"testCaseName":"ACLTest","group":"All_Int","projectType":"GEN","vtName":"NEW_VT","status":"ACTIVE","canOrder":"Yes","expectedResult":"duplicateacltrue"

2,"testCaseName":"DCLAddTest","group":"India_Int","projectType":"GEN_NEW","vtName":"OLD_VT","status":"ACTIVE","canOrder":"Yes","expectedResult":"invalidfeaturesacltrue"

当我运行此代码时出现此错误-

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1

Example.main(Example.java:33)

谁能帮助我修复代码并找出程序中的错误
