Map contains key is case sensitive

 Here is my previous post related to map contains method. 

How contains key method works ? Does it allow partial matches or exact matches ?

We know map contains key method is case sensitive. if you are create a key using First Name , Last Name and DOB to find unique Account record then system will consider 2 different record for below scenario.

1. First Name - "Capital"  Last Name- "Testing" DOB- 01/01/1989

2. First Name - "CAPITAL" Last Name - "TESTING" DOB- 01/01/1989

The work wound is 

map<String,Account> map_Name_Acc = new map<String,Account>();

String sKey = '';

for(Account acc:[SELECT firstname,Lastname,DOB__c from Account limit 10]{

    sKey = acc.FirstName+'_'+ acc.LastName+'_'+acc.DOB__c; // this will create duplicate records since key is case sensitive

 sKey = acc.FirstName.toLowercase()+'_'+ acc.LastName.toLowercase()+'_'+acc.DOB__c; 

}

toLowercase() - convert name to lower case, "CAPITAL" and "Capital" will be "capital"

How to split String from the character '*' ?

 This is a bug in split function, it does not work for '*'  or '+'.  We will get runtime error.

System.StringException: Invalid regex: Dangling meta character '*' near index 0 * 

String sBody = '*   Building Name:Brookwood Gardens  *   Is your unit isolated with barrier systems in place?Yes  *   Does your unit have its own supplies?Yes  *   Does your unit have any additional infection control equipment?HVAC filters: YesUVC lights: Yes';

List<String> strList = sBody.split('*'); // This will throw error.

system.debug('strList '+strList);

Solutions: List<String> strList =sBody.split('\\*'); // This will solve.
