.length() vs .getText().length() vs .getText().toString().length()
<p>For example in the code below <code>a</code> and <code>b</code> and <code>c</code> are equal.</p>

<pre><code>EditText editText;
editText = (EditText) findViewById(R.id.edttxt);

editText.setText("1234");

int a, b, c;
a = editText.length();
b = editText.getText().length();
c = editText.getText().toString().length();
</code></pre>

<p>What is difference between <code>length()</code> and <code>getText().length()</code> and <code>getText().toString().length()</code>?</p>
