How to set a default value using getter and setter

Hi I am trying to set a default value 00 for a field in domain file that contains getters and setters.

When no data is inserted, it should have a value of 00.

private String tapeStartHour;

public String getTapeStartHour() {
return tapeStartHour;
}

public void setTapeStartHour(String tapeStartHour) {
this.tapeStartHour = tapeStartHour;
}

But I dont know where I should put 

set value='00'

Can anyone help?

Try this-

private String tapeStartHour;

public String getTapeStartHour() {
 if(tapeStartHour == null)
     setDefault(); 

return tapeStartHour;
}

public void setTapeStartHour(String tapeStartHour) {
      if(tapeStartHour == null)
           setDefault();
this.tapeStartHour = tapeStartHour;
}

private void setDefault() {
  tapeStartHour = '00';
}

Simply using:

private String tapeStartHour ="00";

public String getTapeStartHour() {
return tapeStartHour;
}

public void setTapeStartHour(String tapeStartHour) {
this.tapeStartHour = tapeStartHour;
}

P.S. You cannot use '' notation. It is used for char. For String you have to use "" notation.

Set the value on the declaration:

    private String tapeStartHour = "00";

Or, on your getter:

    public String getTapeStartHour() {
        return tapeStartHour.equals("") ? "00" : tapeStartHour;
    }
