        public static void main (String args[]){

                boolean guess = true;
                boolean reply = true;



                while (reply == true){
                       

                                Random random = new Random();

                                Scanner scanner = new Scanner(System.in);

                                while (guess == true){



                                        System.out.println("Enter a number 1-100");
                                        int getnum = scanner.nextInt();

                                                System.out.println("Too small");
                                                System.out.println(" ");

                                                System.out.println("Too Large");
                                                System.out.println(" ");
                                        }
                                        else if (getnum == ran_num){
                                                System.out.println("You guessed it! The number is " + ran_num);
                                                System.out.println(" ");

                                                System.out.println("Do you want to keep playing?");
                                                if (scanner.next().equalsIgnoreCase("Yes")){
                                                        reply = true;
                                                }
                                                else{
                                                        guess = false;
                                                }

                                        }

                                }
                        }
             }

}


I keep playing till the second round and so on, the secret number still remains the same.
How do I generate a new one?

code:
Random random = new Random();


Try moving that outside the loop.

Do you mean by that?
I tried it and it still doesn't work.

Oops, my bad.
code:
int ran_num = random.nextInt(100);


Try moving that line into the 2nd loop.

But that will changes the secret number every time i make a guess

When is 'reply' ever false?

But even if i change the guess == false to replay == false, it wont make any different

Oh, I found the actual problem at last.

code:
if (scanner.next().equalsIgnoreCase("Yes")){
    reply = true;
}
else{
    guess = false;
}


Have a good look at that code, and tell me when your loops exit.

i don't see anything there Sad
so when i type yes to replay the game and if i type no for the (guess = false / reply = false) it stops?

code:

program
        do replay game loop
                make random value
                contine choose loop = true
                replay game = false
               
                do continue choose loop
                        get choice
                        was choice to small?
                                if yes then
                                        say to small
                                else was to large?
                                        say to large
                                else
                                        you guessed it
                                        continue choose is false
                                       
                                        do you want to play again?
                                                replay game true?
                                        else
                                                replay game false!
                                        end if
                                end if
                while continue choose is true
        while replay game equal true

        print out "END OF GAME"
end program
