I'm trying to create an APEX Batch Class on custom object, but getting an error

Question

Getting an error when trying to create this batch class. Could you advise what I'm doing wrong?

Error: Compile Error: Class LocationProcessorBatch must implement the method: void Database.Batchable.execute(Database.BatchableContext, List) at line 1 column 14

global class LocationProcessorBatch implements Database.Batchable<sObject> {

global Integer count = 0;

global Database.QueryLocator start(Database.BatchableContext bc){
    return Database.getQueryLocator('Select Id, Next_Inspection_Date__c FROM SVMXC_Site__c');
}

global void execute(Database.BatchableContext bc, List<SVMXC_Site__c> l_list){        
    List<SVMXC_Site__c> l_list_new = new List<SVMXC_Site__c>();
    for(SVMXC_Site__c l:l_list){
        l.Next_Inspection_Date= Month()+'/15/'+Year();
        l_list_new.add(l);
        count+=1;
    }
    update l_list_new;
}

global void finish(Database.BatchableContext bc){
    System.debug('Count='+count);
   }
}

Answer 1

Your issue is on this line:

l.Next_Inspection_Date= Month()+'/15/'+Year();

You have missing __c in the field name.

It should be written as one or other as below.

1. Assuming you are using month() and year() methods from Date class on a date variable:

   Date myDate = date.newInstance(2019, 10, 29);
   l.Next_Inspection_Date__c = myDate.month() + '/15/' + myDate.year();
   

   OR

2. Assuming you already have a Month(), and Year() methods defined in your class.

   l.Next_Inspection_Date__c = Month() + '/15/' + Year();
