im making a program that uses an array to store a guestlist. One of the options in the menu is to add a guest, but when i try this option it doesnt wait for user to make its name input and immedietly jumps to the next statement wich asks for the age. Please help!

    else if(choice==3){
      System.out.print("Name of guest: ");
      String name = input.nextLine();
      System.out.print("Age of guest: ");
      String age = input.nextLine();
      addGuest(name,age);
      }

output: Name of guest: Age of guest:

Update: I managed to solve the problem by adding input.nextLine(); after the first print. I dont really understand the explanation given here Scanner is skipping nextLine() after using next() or nextFoo()? but it worked.

Can you provide more of your code please? have you created a new Scanner object? – BeerusDev Oct 07 '20 at 18:59
How have you initialized the Scanner? Should be input = new Scanner(System.in); – A G Oct 07 '20 at 19:04
Right after all of the the nextFoo() line, please put a print statement showing what was input. This should answer your question – NomadMaker Oct 07 '20 at 20:10
