Explanation / Answer

import java.util.Scanner;
public class ParseStrings {
   public static void main(String[] args) {
   /* Type your code here. */
       Scanner scan = new Scanner(System.in);
      
       int x = 0,y = 0,z = 0, sum = 0, grade= 0;
       if (1 + x > Math.pow(x, Math.sqrt(2))) {
           y = y + x;
           }
      
       String letterGrade = "F";
       if (grade >= 90) { letterGrade = "A"; }
       if (grade >= 80) { letterGrade = "B"; }
       if (grade >= 70) { letterGrade = "C"; }
       if (grade >= 60) { letterGrade = "D"; }
      
      
       while(true){
       System.out.print("Enter input string: ");
       String s = scan.nextLine();
       if(s.equalsIgnoreCase("q")){
           break;
       }
       else if(!s.contains(",")){
           System.out.println("Error: No comma in string");
       }
       else{
           String firstWord = s.split(",")[0].trim();
           String secondWord = s.split(",")[1].trim();
           System.out.println("First word: "+firstWord);
           System.out.println("Second word: "+secondWord);
       }
      
       }
   return;
   }
  
   }

Output:

Enter input string: Jill Allen
Error: No comma in string
Enter input string: Jill, Allen
First word: Jill
Second word: Allen
Enter input string: Golden , Monkey
