How to schedule a batch class without scheduler class in salesforce?

Hello ,

you can get help from this code below:-

public class keepTruckInBatchForVehicleUpadte implements database.Batchable<decimal>, Database.AllowsCallouts, database.stateful, schedulable

{

public  List<decimal> pageList;

public  boolean executeNext;

public  List<Vehicle_Update__c> lastvehicleUpdates;

public keepTruckInBatchForVehicleUpadte()

{

executeNext=false;

pageList = new List<decimal>();

}

public keepTruckInBatchForVehicleUpadte(List<decimal> counts, boolean bool)

{

executeNext = bool;

pageList = new List<decimal>();

pageList.addAll(counts) ;

}

public iterable<decimal> start(Database.BatchableContext BC)

{

return pageList;

}

public void execute(Database.BatchableContext BC, List<decimal> scope)

{

decimal count = scope[0];

keepTruckInApiCallouts.getVehicleLocations(count);

string returnResponse = keepTruckInApiCallouts.getVehicleLocations(count);

keepTruckInApiCallouts.keepTruckVehicleUpdate(returnResponse);

// Deserializes the returnResponse JSON string into collections of primitive data types.

Map<String, Object> jsonObjects = (Map<String, Object>) JSON.deserializeUntyped(returnResponse);

Map<String, Object> paginationobjs = (Map<String, Object>)jsonObjects.get(‘pagination’);

decimal totalRecords = integer.valueof(paginationobjs.get(‘total’));

decimal perPageRecs = integer.valueof(paginationobjs.get(‘per_page’));

decimal totalPages = math.ceil(totalRecords/perPageRecs);

if(totalRecords > perPageRecs && executeNext == true)

{

pageList.clear();

for(count = 2; count <= totalPages; count++)

{

pageList.add(count);

}

}

else

{

executeNext = false;

}

}

public void finish(Database.BatchableContext BC)

{

if(executeNext == true)

{

database.executeBatch((new keepTruckInBatchForVehicleUpadte(pageList, false)),1);

}

}

public void execute(SchedulableContext SC)

{

lastVehicleUpdates = [select id from Vehicle_Update__c];

delete lastVehicleUpdates;

database.executebatch((new keepTruckInBatchForVehicleUpadte(new List<decimal>{1}, true)),1);

}

}
