How to get RecordType Id in apex without SOQL

Basically to avoid SOQL Limit we can use dynamic apex to get RecordTypeId . So we can get a particular record type Id of a particulat Sobject or we can get all recordType id of one sobejct in map .
Here I have created one util class which has two methods .One will give you Id of particular recordType , however we need to pass the Sobejct Name and recordType Name as parameter .

Second method will return you a map of all recordType name and related Id ,where we need to pass only sobject name .

public class RecordTypeUtil {

     //Method to get the  recordTypeId 
     Public static Id recordTypeId(string obj,string recName){
        Id recTypeId;
        if(obj!= null && recName != null){
            recTypeId= Schema.getGlobalDescribe().get(obj).getDescribe().getRecordTypeInfosByName().get(recName).getRecordTypeId();
        }  
        return recTypeId;  
     }

    //Method to get the map of recordType Name as key and recordTypeId as value 
     Public static Map<String,Id> recordTypeMap(string obj){
        Map<String,Id> recTypeNameWithIdMap=new Map<String,Id>();
        if(obj!= null){
            for(Schema.RecordTypeInfo recInfo : Schema.getGlobalDescribe().get(obj).getDescribe().getRecordTypeInfosByName().values()){
                recTypeNameWithIdMap.put(recInfo.getName(),recInfo.getRecordTypeId());
            }
        }
        return recTypeNameWithIdMap;
    } 
}

Both are static methods you can call with class name like below .

Example 1.

Id recId=RecordTypeUtil.recordTypeId('Account','Draft');

Example 2.

Map<String,Id> recTypeIdMap=RecordTypeUtil.recordTypeMap('Account');

If you want only single record type Id then you can also use below code which 

 will give you particular record type id of a object . Just replace object name/record type 

Name of your desired .

Id recordTypeId = Schema.SObjectType.OBJECT NAME.getRecordTypeInfosByName().get('RecordType Name').getRecordTypeId(); 

I think this will help please suggest to improve .
