simple conditional in java (unexpected issue)

Question

I have an unexpected issue when using a conditional operator in java. The code is supposed to check if the ArrayList contains a specific string, then it returns tru

Answer 1

Your List does not contain the String that equals ".". You have a String that contains a . but that is not the same thing. You can do that with String.contains(CharSequence),

public boolean isDone() {
  List al = new ArrayList(); // <-- I would use the Interface type
  al.add(d1.getText());
  al.add(d2.getText());   
  al.add(d3.getText());    
  al.add(d4.getText());   
  al.add(d5.getText());

  // If any String in al contains a '.' return false, else true.
  for (String str : al) {
    if (str.contains(".")) {
      return false;
    }
  }
  return true;
}
