那你試試？看起來'String.replaceAll（「\\ [\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'）」可以幫助你。或者更簡單的方法來做到這一點：這是JSON數據，所以使用JSON解析器。 –

你只想要雷雨「」和[] ..爲什麼不嘗試替換（）？ – TheLostMind

@ArnaudDenoyelle：我試過它不起作用 – Giridharan

您可以使用下面的代碼

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

您可以通過刪除括號來獲得輸出。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);

輸出此代碼

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

@asmalinidi：我需要從字符串中刪除引號 – Giridharan

@Giridharan你也可以刪除引號String output3 = output2.replace（「\」「，」「）;使用此代碼 – asmalindi

：它工作。感謝您的迴應 – Giridharan

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));
