How do I replace an inputted string word to a set of one character: For example: The string is: Hello Word The output should be: aaaaa aaaa
I've encountered an interesting scenario. For some reason strip() against blank string (contains whitespaces only) significantly faster than trim() in Java 11.
So I know that you should declare char arrays to be one element bigger than the word you want to put there because of the /0 that has to be at the end, but what about char arrays that I don't want to use as words?
I want to find if given String "99999999999999999999999999" or any massive number which would not fit in any datatype.I would like to find if that number is bigger than Integer.MAX_VALUE
I am trying to remove the last "," of a string however i am getting an error stating that System.ArgumentOutOfRangeException: 'StartIndex cannot be less than zero.
I was trying to separate the elements from a multiline string:My aim is to get a list lst such that:My attempt so far is this:
