accepting value in edittext even if it has spaces

i have this code in my app. which accepts the value of the edittext

        if (ans.equalsIgnoreCase("bag")) {

                btnEnter.setEnabled(false);
            int a=Integer.parseInt(textView2.getText().toString());
            int b=a+10;
            String s1 = String.valueOf(b);
            textView2.setText(s1);  
            Toast.makeText(getApplicationContext(), "Correct",Toast.LENGTH_SHORT).show();

my problem is if the user puts a single space in the edittext then proceeds with the "bag" it still prompts wrong like this for example

" " = space

" " bag ----- wrong bag ----- correct

how can i set that with space it can accept

      String ans2 = ans.trim();
      if (ans2.equalsIgnoreCase("bag")) {

        btnEnter.setEnabled(false);
        int a=Integer.parseInt(textView2.getText().toString());
        int b=a+10;
        String s1 = String.valueOf(b);
        textView2.setText(s1);  
        Toast.makeText(getApplicationContext(), "Correct",Toast.LENGTH_SHORT).show();

trim() function

Returns a copy of the string, with leading and trailing whitespace omitted.

Since @ρяσѕρєя K deleted his answer before I got back to delete mine I will add his simplified edit. Change

if (ans2.equalsIgnoreCase("bag")) {

to 

if (ans.trim().equalsIgnoreCase("bag")) {

then no need for 

String ans2 = ans.trim();

But using a second variable may be better for readibility or functionality in certain situations

Edit To take care of in between spaces you might try

if (!ans.contains("") && ans.trim().equalsIgnoreCase("bag")) {

Not sure why that doesn't work but you can use the replace function for Strings

       String ans2 = ans.replace(" ", "");
       if (ans2.trim().equalsIgnoreCase("bag")) {
