for each loop

hi i want two compare two values in a loop for ex my code is 
for(String sr : uniqueData){
        list<String> dr = sr.split('~',2); 
        agm = dr[0];
        dvr = dr[1];
}

Hi,

Please try below code. 
List<List<String>> dr;
int i=0;
for(String sr : uniqueData){
        //list<String> dr = sr.split('~',2); 
		dr.add(sr.split('~',2));
		if(i>0){
			String agmPrevious = dr[i-1];
			String dvrPrevious = dr[i-1];
			
			String agmCurrent = dr[i];
			String dvrCurrent= dr[i];
			
			//if(agmPrevious ==agmCurrent){
				//YOUR LOGIC
			}
		}
		i++;
        
}

Hi,

   If you are using uniqueData as Set<String> it won't accept duplicate records.So no need to compare it.If you are using List<String> you need to compare.


Thanks,
