   The purpose of this is to convert a string to an integer so I can later then process it in for loops.
   
   Say that I had a String made from an args,
   String s = args[0].toString();
   
   How would I check if s is an integer and how would I convert it to integer form?

   int value = Integer.parseInt(String);

   stormneo7 Add this method into your class
   

   Code:java

   public boolean isInteger(String input) {
   try {
   Integer.parseInt(input);
   return true;
   }
   catch(NumberFormatException e) {
   return false;
   }
   }

   
   And simply do this
   

   Code:java

   if(isInteger(s)){
   // if string is integer
   int value = Integer.parseInt(s);
   // converts the string into int.
   }else{
   // if string is not integer
   }
