Question

I WANT TO IMPLEMENT THIS IN JAVA PLEASE I want to create a small user input system for a university student, where they put the season and year of when they started their uni course. For example the system will ask "What year did you start your degree?", the user will input "Autumn/2022" as a string. Now from a string format as shown, it should take that user input and calculate for example +2 or +3 years to the date. Also it needs to be able to change from Autumn, to another season depending on the amount of years it takes. So if the course will take 3 years, the student will finish "Summer/2025". How can I implement this?

Code:

package Test;

import java.util.Scanner;

public class CourseTerm {

   public static void main(String[] args) {
       Scanner input=new Scanner(System.in);
       String seasonAndYear,season;
       int year ;
       while(true){ //loop until proper input is given
           System.out.print("What season and year did you start your degree? (eg. Autumn/2022) :");//asking for input
           seasonAndYear=input.nextLine();
           //checking for proper input
           if(seasonAndYear.contains("/")) {
               String[] arrOfStr = seasonAndYear.split("/");
               if(arrOfStr.length==2) {//checking for proper input
                   try
                   {
                       year=Integer.parseInt(arrOfStr[1]);
                       season=arrOfStr[0];
                       //checking for proper input
                       if(season.equalsIgnoreCase("Autumn") || season.equalsIgnoreCase("Summer")||season.equalsIgnoreCase("Spring")||season.equalsIgnoreCase("Winter")) {
                           season=getEndSeason(season); //calling function to get end of the season
                           System.out.println("For 2 year course you will end in :"+(year+2)+"/"+season);//Printing for 2 year course
                           System.out.println("For 3 year course you will end in :"+(year+3)+"/"+season);//Printing for 3 year course
                           break;
                       }else {//Printing error message
                           System.out.println("Invlaid Input. Please give again... Format is Autumn/2022");
                       }
                   }catch(Exception e) {//Printing error message
                       System.out.println("Invlaid Input. Please give again... Format is Autumn/2022");  
                   }
                      
               }else {//Printing error message
                   System.out.println("Invlaid Input. Please give again... Format is Autumn/2022");
               }
           }else {//Printing error message
               System.out.println("Invlaid Input. Please give again... Format is Autumn/2022");
           }
       }
       input.close();
   }

   private static String getEndSeason(String season) {
       season=season.toLowerCase();
       //returning season based on start season
       if(season.equalsIgnoreCase("autumn")) {
           return "Summer";
       }else if(season.equalsIgnoreCase("summer")) {
           return "Spring";
       }else if(season.equalsIgnoreCase("spring")) {
           return "Winter";
       }else if(season.equalsIgnoreCase("winter")) {
           return "Autumn";
       }
       return null;
   }

}
