How to use class as member variable with arduino

_keypad.begin() gets called in the constructor. I don't believe there is a reason to call it twice. Thank you for the note about using begin()...I will switch.

So the test script worked perfectly...all I am doing currently is

void Keyblock::getKey() {
  char key = _keypad.getKey();
  if (key != NO_KEY){
    _debug.write("Key Pressed : ").line(key);
  }
}

So maybe the issue is actually something do with my debug class?

class Debug {
  private:
    bool _state = false;
  public:
    void init();
    Debug& line(const char *str);
    Debug& line(int);
    Debug& write(const char *str);
    Debug& write(int);
    void newline();
};


void Debug::init(){
  if (!_state){
    Serial.begin(9600);
    delay(1000);
    _state = true;
    line("Debug Started");
  }
}
Debug& Debug::line(const char *messageChar) {
  if (_state){
    const char *p;
    p = messageChar;
    while (*p) {
        Serial.print(*p);
        p++;
    }
    newline();
  }
  return *this;
}
Debug& Debug::line(int messageInt) {
  if (_state){
    Serial.print(messageInt);
    newline();
  }
  return *this;
}
Debug& Debug::write(const char *messageChar) {
  if (_state){
    const char *p;
    p = messageChar;
    while (*p) {
        Serial.print(*p);
        p++;
    } 
  }
  return *this;
}
Debug& Debug::write(int messageInt) {
  if (_state){
    Serial.print(messageInt);
  }
  return *this;
}
void Debug::newline() {
  if (_state){
    Serial.println();
  }
}
