How can I make this code shorter? The code I am using is so long. Just making one simple level is taking about 100 lines of code.public class Sister_age_guesser {    public static void main(String[] args) {         Scanner input = new Scanner(System.in);         System.out.println(Sherlock holmes - The game);          System.out.println( This is a mystery game where you have to find clues after solving math sums);          System.out.println(Write your name );              String name = input.nextLine();              System.out.println(------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------);           System.out.println(Instructions);            System.out.println(1.This game has 1 level );            System.out.println(2.Clues will be given before you write down the answer.Writing the correct answer will unlock the next clue );            System.out.println(------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------   );           System.out.println(  FLORENTINES MURDER );           System.out.println(   );           int SisterBirthday = 1997;           System.out.println(FIND THE MURDER WEAPON);           System.out.println( );           System.out.println(Clues :-);           System.out.println(  );           System.out.println( 1. This number is 1000 added to itself. 2. cut 6 into 2 pieces and take half of it and subtract it from the result from the previous clue );           int number = input.nextInt();            if(number < SisterBirthday)            {                   System.out.println(name +  , you need more practice + name);                 System.exit(0);             }             else if(number > SisterBirthday)            {                System.out.println( cant u solve this simple clue  + name +  ?);               System.exit(0);              }            else                 System.out.println(Good thing you found out the murder weapon.We found some fingerprints on the weapon .
