How to add and remove values from Picklist Value sets (Global Pick list) ?

Hi Team,
 
I have created a Picklist Value set and I referred this to a custom picklist field. Now the requirement is I need to update the Picklist value set through apex on the batch run. Help me. 

Thank you
Sandeep.

Hi Sandeep,
To access picklist values from a trigger or server controller in Apex, you can use dynamic Apex. It lets you analyze objects and fields programmatically with methods from the Schema namespace. (https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_namespace_Schema.htm) 
The following code sample shows how you can retrieve picklist values for the “Industry” field of the “Account” object as a list of Schema.PicklistEntry (https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_class_Schema_PicklistEntry.htm) using getDescribe() and getPicklistValues(): 
// Describe the Account.Industry field
Schema.DescribeFieldResult fieldDescription = Account.Industry.getDescribe();
// Get picklist values from field description
List entries = fieldDescription.getPicklistValues();
// Do something with entries
for (Schema.PicklistEntry entry : entries) {
/*
entry.getValue()
entry.getLabel()
entry.isActive()
entry.isDefaultValue()
*/
}
