Don't understand how the program knows what to do if the answer is no. Can someone explain the code very simply???

console.printf("I do not understand: %s", question); anyQuestions = console.readLine("Are there any more questions %n ");

This specific part doesn't make sense to me.

The first line will print out "I do not understand: " then it will print the contents of the variable question (if it has been declared). The second line will take input from the user after prompting: "Are there any more questions" and it will store the input in variable anyQuestions if this variable has been declared.

The %s is a String place holder for the variable listed After the following comma. The %n is a new line character, (kind of like hitting enter after typing a sentence).

If "no" is input by the user then it will go into variable anyQuestions. The only way for the program to respond to an input of "no" is to run a conditional statement to test if anyQuestions is equal to no.

Like this:


  //run this code


  // then run this code instead
