Check if an Edit Text that only accepts number is not empty and the number is equal or less than 100

I'm building an application for receiving grades and I want to make sure that the Edit Texts are not empty and the values are less or equal to 100 I wrote this line but it crashes the application

if(Integer.parseInt(editText.gettext().toString()) > 100 || editText.getText().toString().trim().length() == 0)
{
//Error message for example
} 

and this is the logCat

In your xml where you have declared edittext make sure that you put the following attribute in edittext element

android:inputType="number"

And change above code to this :

 if(editText.getText().toString().trim().isEmpty() || Integer.parseInt(editText.gettext().toString()) > 100 )
    {
    //Error message for example
    } 

you first need to check if text is not empty
