Sai,

 

You can use containsAll method of set only if you are comparing two sets equality.

 

use contains instead

 

if(sub2.Contains(rec.Substring__c))

 

Eg:

set<string> mySet = new Set<String>{'abc', 'efg'};

system.debug('Test>>>> '+mySet.contains('abc'));

To do that you will have to loop through the set and use a flag to determine if any value was not matched in the string

 

Boolean noMatch = false;

For(String s : sub2){

 if(!rec.substring__c.contains(s))

    noMatch = true;

}

 

if(noMatch = false){

   //all values matched process here

}
