Code after while loop not accepting input [Java] -


so, in program when while loop ends, displays "you win!" , execute code asking if user wants view credits. however, scanner/input isn't being accepted after question , program ends without accepting input. 

scanner scan = new scanner(system.in);          system.out.println("would play game called threes? y/n");         string answer = scan.nextline();        //simple yes or no          if (answer.contains("y") || (answer.contains("y"))) {             system.out.println("ok, want know how works? y/n");             string answer2 = scan.nextline();             if (answer2.contains("n") || (answer2.contains("n"))) {                 system.out.println("ok, enter single number.");                  int mistake = 0;    //used counter number of division mistakes made                 int numstart = scan.nextint();  //first number input                 int current = numstart;     //current number displayed - starts first number                  system.out.println("enter 1 or -1 if you're adding or subtracting, , 0 divide.");                 system.out.println(numstart);       //displays first number input                 int input = scan.nextint();     //first function performed user                  while (current != 1) {      //the game run until number '1' reached                     if (input == 1) {       //if '1' input, add 1 number, , display new number                         current++;                         system.out.println(current);                         input = scan.nextint();                     }                     if (input == -1) {      //if '-1' input, subtract 1 number, , display new number                         current--;                         system.out.println(current);                         input = scan.nextint();                     }                     if (input == 0) {       //if '0' input, try divide                         if (current % 3 != 0 && current != 1) {     //if can't divide three, try again                             system.out.println("try again.");                             mistake++;                             input = scan.nextint();                         }                         if (current % 3 == 0) {     //if can divide, , display new number                             current = current / 3;                             system.out.println(current);                             input = scan.nextint();                         }                     }                     if (input == 69 || input == 666)     //cheat code! if input 69 or 666, automatically win                         break;                     if (((input > 1) && (input != 69) && (input != 666)) || input < -1) {        //if input not valid, try again , display error                         system.out.println("error - wrong input.");                         input = scan.nextint();                     }                 }                 system.out.println("you win! mistakes: " + mistake + "\n");        //will display win condition, , amount of division errors                 system.out.println("thank playing threes \n - chris burbach");             }             system.out.println("credits? y/n");             string credits = scan.nextline();              if(credits.contains("y")||credits.contains("y"))             {                 system.out.println("\n***********************************************************************");                 system.out.println("*threes: game of dividing 3 - inspired boredom in class*");                 system.out.println("***********************************************************************");             }             else                 system.out.println("ok, have nice day.");             if (answer2.contains("y") || answer2.contains("y")) {                 system.out.println("ok, first enter number, , either enter '1' or '-1' add or subtract 1 respectively.

sorry confusion, figured out. after each instance of "you win!", outside of nested if statement, needed addscan.nextline(); because of returning newline character , terminating program due empty input.
