Answer 1

You can also do

String person1 = "Joe Smith"; // contains "Joe"
String person2 = "Jasha Thompson"; // contains "Jasha"
String person3 = "Jasha Joesephson"; // contains "Joe" and "Jasha"
String person4 = "Steve Smith"; // contains neither

public boolean containsJoeOrJasha(String stringToCheck) {
  return !Collections.disjoint(
    Arrays.asList(stringToCheck.split(" ")),
    Arrays.asList("Joe", "Jasha"));
}

Collections.disjoint returns true if the two collections are disjoint, meaning that they have no elements in common. So...

jshell> containsJoeOrJasha(person1)
$33 ==> true

jshell> containsJoeOrJasha(person2)
$34 ==> true

jshell> containsJoeOrJasha(person3)
$35 ==> true

jshell> containsJoeOrJasha(person4)
$36 ==> false
