Answer 1

您可以使用以下代码

   states = states.replace("[","").replace("]","").replace("\"", "");

Answer 2

你可以通过删除括号来获得输出。例如

 String input = "[[\"<Select>\"],[\"Andaman and Nicobar\"],[\"Andhra Pradesh\"],[\"Arunachal Pradesh\"],[\"Assam\"],[\"Bihar\"],[\"Chandigarh\"],[\"Chattishgarh\"],[\"CHO Region\"],[\"Dadra & Nagar Haveli\"],[\"Daman & Diu\"],[\"Goa\"],[\"Gujarat\"],[\"Haryana\"],[\"Himachal Pradesh\"],[\"Jammu and Kashmir\"],[\"Jharkhand\"],[\"Karnataka\"],[\"Karnataka Chit\"],[\"Kerala\"],[\"Lakshadweep\"],[\"Madhya Pradesh\"],[\"Maharashtra\"],[\"Maharashtra Chit\"],[\"Manipur\"],[\"Meghalaya\"],[\"Mizoram\"],[\"Nagaland\"],[\"New Delhi\"],[\"NORTH\"],[\"Orissa\"],[\"Pondichery\"],[\"Punjab\"],[\"Rajasthan\"],[\"Sikkim\"],[\"Tamil Nadu\"],[\"Tripura\"],[\"Uttar Pradesh\"],[\"Uttaranchal\"],[\"WEST\"],[\"West Bengal\"],null]";
    String output1 =  input.replace("[", "");
    String output2 =   output1.replace("]", "");
    System.out.println("output :"+output2);

此代码的输出

output :"<Select>","Andaman and Nicobar","Andhra Pradesh","Arunachal Pradesh","Assam","Bihar","Chandigarh","Chattishgarh","CHO Region","Dadra & Nagar Haveli","Daman & Diu","Goa","Gujarat","Haryana","Himachal Pradesh","Jammu and Kashmir","Jharkhand","Karnataka","Karnataka Chit","Kerala","Lakshadweep","Madhya Pradesh","Maharashtra","Maharashtra Chit","Manipur","Meghalaya","Mizoram","Nagaland","New Delhi","NORTH","Orissa","Pondichery","Punjab","Rajasthan","Sikkim","Tamil Nadu","Tripura","Uttar Pradesh","Uttaranchal","WEST","West Bengal",null

Answer 3

您可以使用模式：

StringBuilder myFinalString = new StringBuilder();

String myString = "[[\"<Select>\"],[\"Andaman and Nicobar\"],[\"Andhra Pradesh\"],[\"Arunachal Pradesh\"],[\"Assam\"],[\"Bihar\"],[\"Chandigarh\"],[\"Chattishgarh\"],[\"CHO Region\"],[\"Dadra & Nagar Haveli\"],[\"Daman & Diu\"],[\"Goa\"],[\"Gujarat\"],[\"Haryana\"],[\"Himachal Pradesh\"],[\"Jammu and Kashmir\"],[\"Jharkhand\"],[\"Karnataka\"],[\"Karnataka Chit\"],[\"Kerala\"],[\"Lakshadweep\"],[\"Madhya Pradesh\"],[\"Maharashtra\"],[\"Maharashtra Chit\"],[\"Manipur\"],[\"Meghalaya\"],[\"Mizoram\"],[\"Nagaland\"],[\"New Delhi\"],[\"NORTH\"],[\"Orissa\"],[\"Pondichery\"],[\"Punjab\"],[\"Rajasthan\"],[\"Sikkim\"],[\"Tamil Nadu\"],[\"Tripura\"],[\"Uttar Pradesh\"],[\"Uttaranchal\"],[\"WEST\"],[\"West Bengal\"],null]";
Pattern stringPattern = Pattern.compile("\"[^\"]*\"|null");
Matcher matcher = stringPattern.matcher(myString);

while(matcher.find()) {
    myFinalString.append(',').append(matcher.group());
}

System.out.println(myFinalString.toString().substring(1));
