I get this error when I try to save my batch apex test class:

Error: Compile Error: Final member variables can only be assigned in their declaration statement or inside a constructor at line 88 column 16

Any suggestions or help would greatly help me out!

Below is my test class:

@isTest
public class Enrollment_MainProcess_TEST{
 static testMethod void testBatch(){


         /* create user */
         User salesUser =
           [SELECT Name, Lead_Rep_Number__c
            FROM User WHERE Lead_Rep_Number__c != null Limit 1];
            
        /* create account */  
         Account testacct1 = new Account();
         testacct1.Name = 'TestAccount4';
         testacct1.Type = 'Customer';
         insert testacct1;    
            
        /* create opportunity */
         Opportunity testOpp1 = new Opportunity();
         Date closedDate = date.newinstance(1950, 15, 1);
         Date EffectiveDate = date.newinstance(2050, 10, 9);            
         testOpp1.Name = 'Test Opportunity1';
         testopp1.AccountId = testacct1.Id;
         testOpp1.StageName ='Sold';
         testOpp1.CloseDate = closedDate;
         testOpp1.Effective_Date__c =  EffectiveDate;
         testOpp1.SBU__c = 'Small/Medium';
         testopp1.Market_Segment_New__c = '51-199';
         testopp1.Business_type__c = 'Renewal';
         testopp1.Division__c = '51-199 Renewals';   
         testopp1.Underwriting_Entity__c = 'MD';
         testopp1.Lead_Rep_Name_User__c = salesUser.Id;
         testOpp1.GeneralProducer__c = 'Direct';
         testOpp1.System__c = 'NASCO';    
         testOpp1.NASCO_Acct_ID__c = '12234';      
         insert testOpp1;
               
        /* create Product */
         Product2 testProd1 = new Product2();
         testProd1.id = '01t60000002wbRd';
         testProd1.name = 'BC Advantage';
         testProd1.IsActive = True;
         insert testProd1;
         
        /* create Enrollment Import */
         List <Enrollment_Import__c> EnImpts = new List<Enrollment_Import__c>();
         for(integer i = 0; i<200; i++){
         Enrollment_Import__c EnImp = new Enrollment_Import__c(
        
        Account_Name__c = 'TestAccount'+'i',
        Account_Number__c = '1223'+'i',             
        System__c = 'NASCO',
        Contracts__c = 50,
        Processed__c = FALSE,
        Risk__c = 'Non-Risk',
        Rpt_dt__c = '201301',
        Run_Dt__c = '02/09/2013 13:37:21',
        SFDC_Product__c = 'BC Advantage' );
        EnImpts.add(EnImp);
      }
      insert EnImpts;
           

Test.StartTest();
 Enrollment_MainProcess enmp = new Enrollment_MainProcess();
88  enmp.query = 'SELECT id, Rpt_Dt__c, Run_Dt__c, Account_Name__c, Account_Number__c, SFDC_Product__c, Contracts__c, System__c, Risk__c' +
               'FROM Enrollment_Import__c' +
               'WHERE Processed__c = FALSE' +
                'LIMIT 200';
  ID batchprocessId = Database.executeBatch(enmp);
  Test.StopTest();

}

}

Thanks!
