I would like to hear someone explain void methods and return types if they have a chance. Thanks!

void methods, return types

It's simple! The return type is the kind of variable that the method returns. A return type of void means that the method won't return anything at all.

private static void doSomething() {
  // this method doesn't return anything, but it can still do useful things!
}

private static String getHello() {
  // this method returns a String!
  return "Hello!";
}

// Let's call the methods! Imagine that we are in a relevant place in the code.
// The first one doesn't return anything.
doSomething();
// But this method does! Store it in a variable.
String example = getHello();
