public class checktest

Work_Order__c work = new Work_Order__c();
String s, s1, s2, s3='';
String a = 'Hello. \n Welcome to salesforce, \n Name \n Asian Paints \n WO Number \n 12345678 \n Account Id \n 1547586597';
List<String> lst = a.split('\n');
for(integer i=0;i<lst.size();i++)
{
s=lst.get(i);
if(s.contains('Hello. \n Welcome to salesforce, \n Name \n Asian Paints \n WO Number \n 12345678 \n Account Id \n 1547586597'))

On a general note, if we attempt to access an element at row 0, the code will throw an error if no data exist at row 0.
To fix this, check whether there are records in the list you have defined in your code before accessing it.
Sample code
List lstAccount = [Select Id, Name from Account Limit 10]; // Before processing the list check if its empty or not // It will go inside the loop only if the List is having values in it. if(lstAccount.size() > 0) { // Do something with lstAccount[0].Name } // If you try to access lstAccount[0] without empty check then it will obviously throw that error!!Reference: https://help.salesforce.com/articleView?id=000329067&type=1&mode=1

Try Below Code Changes Are In Bold =lst[i];
public class checktest { public static void force() { Work_Order__c work = new Work_Order__c(); String s, s1, s2, s3=''; String a = 'Hello. \n Welcome to salesforce, \n Name \n Asian Paints \n WO Number \n 12345678 \n Account Id \n 1547586597'; List<String> lst = a.split('\n'); for(integer i=0;i<lst.size();i++) { s=lst.get(i); if(s.contains('Hello. \n Welcome to salesforce, \n Name \n Asian Paints \n WO Number \n 12345678 \n Account Id \n 1547586597')) { work.Email_Body__c=lst[i]; } if(s.contains('Asian Paints')) { i = i+3; s1=lst[i]; work.Name = s1; } if(s.contains('12345678')) { i = i+5; s2=lst[i]; work.WO_Number__c =double.valueOf(s2) ; } if(s.contains('1547586597')) { i = i+7; s3=lst[i]; work.Account_Id__c =double.valueOf(s3); } } insert work; } }Please Mark It As Best Answer If It HelpsThank You!
