How to get the default picklist value using Apex Class?
Its possible to get the default picklist value using apex class and doesn’t require the SOQL Query and its not against the SOQL Limits as well.
Apex Code Code:
String defaultVal;
Schema.DescribeFieldResult F = Lead.Status.getDescribe();
List <Schema.PicklistEntry> pickVals = F.getPicklistValues();
for (Schema.PicklistEntry av: pickVals) {
if (av.isDefaultValue()) {
defaultVal = av.getValue();
}
}
system.debug(‘Default value is’ + defaultVal);
isDefaultValue – using the keyword we can achieve the default picklist values using apex class/apex triggers.

statusOptions = new List<SelectOption>();
// Use DescribeFieldResult object to retrieve status field.
Schema.DescribeFieldResult statusFieldDescription = Lead. Status.getDescribe();
// For each picklist value, create a new select option
for (Schema.Picklistentry picklistEntry: statusFieldDescription.getPicklistValues())
