Anupama Ramanujan 13 How can we fetch the value from Map based on particular key?
Need to fetch the value from Map based on particular key and assign to a new variable.
If Map is defined like <Id,String> then, want to check if any particular Id is existing in the Map and if it is there in map. The String value for that Id should be assigned to a new String variable. Is it possible to do? If so, how to perform this action.

Lets say you have Map - Map<Id, String> AccountIdAndNameMap = new Map<Id, String>();
then you can check like - AccountIdAndNameMap.containsKey(Id) ;
It will give you whether perticular id exists in map or not.
if you get value then you can assign it to new String variable.
ex,
String Name ;
if(AccountIdAndNameMap.containsKey(Id)){
Name = AccountIdAndNameMap.get(Id);
}
I hope it helps you to resolve your query..
