Get Recordtype Id by Name and Get Recordtype name by Id

Try the below:-

Get Recordtype Id by Name:-

 Id devRecordTypeId=

Schema.SObjectType.Account.getRecordTypeInfosByName().get(‘Development’).getRecordTypeId();

 Here, ‘Development’ is the record type’s name. You shuld use ‘someone’. Also, you will have to specify your SObject type, here I have mentioned Account.

Get Recordtype name by Id:-

for(opportunity opp : trigger.new){

 string recordtypename =

Schema.SObjectType.Opportunity.getRecordTypeInfosById().get(opp.recordtypeid).getname();

}
