how would you code a user input scanner to respond with a set line?

This will probably sound confusing because I'm not entirely sure how to phrase this question, but how would you code a user input scanner to have a set response when someone inputs something, instead of just spitting the line they typed in back out again?

The program doesn't actually spit it back out unless you tell it to in the System.out.println method. When you're taking in user input, assign it to a variable. So Scanner input = new Scanner(System.in); then, String wordEntered = input.nextLine(); this way, you now have their input stored in a variable that you can use throughout your program. To test conditions, you can use either an if statement or switch. When comparing strings, never use ==, always use .equals(). Example: if(wordEntered.equals("Pickles")){ System.out.println("Strange thing to input, but whatever"); Other method switch(wordEntered){ case "hello": System.out.println("something something"); break; case "Rawr": System.out.println("what are you, a dinosaur?"); break; With switch you just use the variable, the switch automatically uses .equals with Strings.

i would use playerAnswer.equalsIgnoreCase(" "){ } just so they can put the word in any case, but what ever is easy for you. :)

Could do that, I could also do (wordEntered.toLowerCase()) or Upper in the switch as well. But that's extra stuff that I didn't feel like writing a paragraph about
