String personFields is read from input. personFields contains values delimited by spaces $(\text{'}\text{'}).$ Assign thirdSpace with the index of the third occurrence of a space $(\text{'}\text{'})$ in personFields. Ex: If the input is Hania Harry Ron Maite Rhys Vicente, then the output is: First three fields: Hania Harry Ron import java.util.Scanner; public class FirstThreeFields $\{$ public static void main$($String$[]$ args$)\{$ Scanner scnr $=$ new Scanner$($System$.$in$)$; String personFields; int i; int numOccurrences $=0$; int thirdSpace $=-1$; personFields $=$ scnr$.$nextLine$()$; System.out.println$("$First three fields: $"+$ personFields.substring$(0,$ thirdSpace$))$; $\}\}$
