If statement is not excuting the statements in the correct order

I am trying to validate my android Edit text box so that when the button is pressed if the Edit Text box is empty a message will appear, i am also validating the Edit text box to make sure that the value entered is a number, if the text box is empty the error message will appear saying that the value must be a number, I think it has something to do with the structure of my if statements but im not sure what. the code below is what i have tried already.

TextView Display;
EditText Input;

Display = (TextView) findViewById(R.id.tvOutput);
Input = (EditText) findViewById(R.id.eName);

try{
    String UserInput = Input.getText().toString();
    int number = Integer.parseInt(UserInput);

    if(!UserInput.isEmpty()){
        if(number == (int) number){
            Display.setText(UserInput);
        }
    }else{
        Display.setText("Please enter a value into the text box");
    }
}catch(Exception  e){
    Display.setText("Please enter a number");
}
