Converting for each loop to for loop java while reading csv data java

Question

I have the following code:

    try (CSVReader reader = new CSVReader(new FileReader(file))) {
            List<String[]> r = reader.readAll();
            r.forEach(x -> System.out.println(Arrays.toString(x)));
        }

@Husseinfo this likely has *nothing* to do with android or any of it's SDKs though. could be a plain java "question" too. — Shark, Apr 07 '21 at 14:00
@Shark Yes it could be a simple java program too, why did you get that offended! I had a similar experience when I wasn't able to use Collections' forEach. Keep relaxed dude. — Husseinfo, Apr 08 '21 at 07:46
@Husseinfo there was no offense, i was just stating that as it is, this question looks nothing like it has anything to do with android. — Shark, Apr 08 '21 at 08:25

    try (CSVReader reader = new CSVReader(new FileReader(file))) {
       List<String[]> r = reader.readAll();
       for(int i =0;i< r.size() ; i++){
           System.out.println(Arrays.toString(r.get(i));
       }
    }

Another Solution :

try (CSVReader reader = new CSVReader(new FileReader(file))) {
   List<String[]> r = reader.readAll();
   for(String[] x : r){
       System.out.println(Arrays.toString(x));
   }
}
