I know how to remove vowels from a String,but how do I remove certain spaces from a string

Question

The code bellow removes the vowels form the string but it does not remove the spaces that corresponds before or after the "_".

public static String removeVowels(String str) {
    str = str.replaceAll("[aeiouAEIOU]",""); 


    return str;

}

public static void main(String[] args) {
    System.out.println("__" + removeVowels(" The Lion king ") + "__");

}
}

Console Output:

__ Th Ln kng __

What the console output should be:

__Th Ln kng__

Not really sure how I would go about doing this without going into the main method and manually removing the spaces.

You're question title is "removing spaces from a string" -- but it sounds like you want a much more specific case - of removing spaces after the first two `_` and before the last two `_`?. From your code it looks like you've created the bug in your test cases: `" Snowboarding school "` has a leading and a trailing space... — Don Cheadle, May 10 '16 at 19:26

Not sure what you're asking, but perhaps you want to trim() your String. This removes white space from the front and back ends of the String:

str = str.replaceAll("[aeiouAEIOU]","").trim();

Use:

str = str.replaceAll("\s*__\s*","");
