Question

I have a string which may or may not end with whitespace and I’m having trouble determining whether that’s the case.

The reason why I am asking this is because I need a good way to calculate the width of the android since my string auto corrects and goes to the next line.

In android it looks like something like this:

 The quick brown fox jumps over the lazy dog

 The quick brown fox jumps over the lazy d - my method substrings the data to fit on screen.

|The quick brown fox jumps over the lazy  | - this is how it would look like on android

|dog---------------(empty space)----------|

Now to rephrase my question I want to know what method do I need to use to check the last character in my string is whitespace?

Answer 1

In short:

boolean isSpace = yourString.charAt(yourString.length() – 1) == ‘ ‘;

EDIT:
After reading the great comment from MH bellow, you should instead use:

boolean isSpace = Character.isWhitespace(yourString.charAt(yourString.length() - 1));

But if you want only to remove the space at the end, you can use the trim() method on the String class:

yourString = yourString.trim();
