Get sObject Name from Record ID.....!!!!

Sometimes there are scenarios when we use

string urlID = ApexPages.currentPage().getParameters().get('id');

and develop the functionality based on urlID .

What should we do, if sometimes urlID gives ID of Object 'X' and sometimes it gives

ID of 'Y' based on business requirement?

Here is what I did....

urlId=ApexPages.currentPage().getParameters().get('id');

Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe();

Map<String,String> keyPrefixMap = new Map<String,String>{};

Set<String> keyPrefixSet = gd.keySet();

for(String sObj : keyPrefixSet){

Schema.DescribeSObjectResult r = gd.get(sObj).getDescribe();

String tempName = r.getName();

String tempPrefix = r.getKeyPrefix();

keyPrefixMap.put(tempPrefix,tempName);

}

string objtempPrefix =urlId.subString(0,3);

string objname =keyPrefixMap.get(objtempPrefix );

system.debug('object name--------------->'+objname );

The first three chars of a record id refer to the sobject the record is based on.

IF urlId is ID of X , objname will be 'X'

IF urlId is ID of Y , objname will be 'y'
