Ways of checking text in the filling form

Question

Hi!
Please tell me, which option to check the presence of text in the filling view is more preferable:

String s = editText.getText().toString();

// 1 option

If(s.equalsIgnoreCase("")) { // some code}

// 2 option

If(s.matches("")) { // some code}

Answer 1

Best way to check edittext was filled or not is using TextUtils class.
In that class use static method isEmpty()

Example
String a = editText.getText().toString();

if(!TextUtils.isEmpty(a)){}
